“A COMPOSITION AND A PROCESS TO OBTAIN WATER AND OIL REPELLING-WRINKLE FREE GARMENT”
Name and address of the applicant: ADITYA BIRLA NUVO LIMITED; Indian Rayon Compound, 362 266 Veraval, Gujarat, India.
Nationality: Indian
The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD
The present disclosure relates to a composition comprising DMDHEU based resin, resin catalyst, polyalkyne, Fluorocarbon which renders the property of water and oil repellency, and Fluorocarbon extender. The present disclosure also relates to a method of obtaining said composition along with a process for obtaining a water and oil repelling, wrinkle free garment, which can withstand up to 50 washes of home laundering. Also, the present disclosure provides for water and oil repelling wrinkle-free garments.
BACK GROUND AND PRIOR ART
The art of making wrinkle free cotton garments is age old, however the aspect of sustainability has always been an issue. The maximum amount of sustainability that is presently offered in the textile industry is about 10-15 washes of the cotton garment. The Finishing or curing treatment of garments to achieve permanent press properties was first presented in the year 1987 at the international AATCC conference in charlotte, NC, USA. The two options that were discussed was firstly vapour phase finishing of cotton garments with gaseous formaldehyde and secondly the DMDHEU immersion finishing. Further, at least one garment manufacturer had begun immersion finishing of cotton garments at that time. However, the trend of ‘finishing treatment’ was established by the mid 1990's. Today, it is observed that there is a wide spread consumer interest in the latest version of permanent press, popularly known as “wrinkle free effect”.
However, several problems have been associated with such garments, even though they have the desired wrinkle free finish, some of these are attracting grease, oil and many water based stains. Hence, arriving at water and oil repellency property has been one of the major targets in textile industry, specifically with respect to fibers.
Nature has already developed an elegant approach that combines chemistry and physics to create surfaces like lotus leaves. The conventional paraffin or silicone based repellent finishing agents are not sufficient to protect the textiles from grease and oil stains and hence fluorocarbon polymers are used. Fluorocarbon polymers commonly known as Fluorocarbons today represent an indefensible part of technology for oil and water

repellent finish. The principle involved in this is very similar to that of non-stick frying pans, wherein the fluoro polymer act like plastic sheet on top of the fabrics, but it would be breathable.

b. treating the sprayed garment to obtain the wrinkle free garment.
In an embodiment of the present disclosure, the spraying is carried out after pre-treatment of the cotton garment.
In another embodiment of the present disclosure, the pre-treatment comprises steps of washing in dispersing and soaping agents for a time duration ranging from about 10 minutes to about 20 minutes, preferably about 15 minutes at a temperature ranging from about 70°C to about 90°C, preferably about 80°C, and hot washing in acetic acid for a time duration ranging from about 5 minutes to about 10 minutes, preferably about 5 minutes at a temperature ranging from about 55°C to about 70°C, preferably about 60°C.

ranging from about 155°C to about 165°C, preferably about 160 °C, for a time duration
ranging from about 10 minutes to about 15 minutes, preferably about 12 minutes.
In still another embodiment of the present disclosure, the garment is wrinkle free for
atleast 50 washes.
The present disclosure relates to a water and oil repelling-wrinkle free cotton garment
obtained by spraying a garment with the composition.
In an embodiment of the present disclosure, the garment is wrinkle free for atleast 50
washes.
In an embodiment of the present disclosure, to overcome the limitations observed in the
currently available technology, the instant study makes efforts to combine along with
wrinkle free effect, the oil and water repelling property in the garments, to get rid of these
problems.
In an embodiment of the present disclosure, the raw fabric is initially processed to convert
the fabric to a desired garment by conventionally known industrial methods. The garment
is further processed to obtain a hydrophobic material free garment. The fabric processing
involves the following steps: singing, desizing, scouring, bleaching, mercerization, Fabric
dyeing and finishing with suebility softener (should not contain any silicon) and finally
sanforising. The treatment with suebility softener prevents the fabric from becoming harsh
which otherwise would restrict the smooth movement of the fabric at the time of sewing.
The end result of this processing is a garment which is silicon free. The processed garment
is thereafter pre-treated additionally by washing with dispersing and soaping agents at a
temperature from about 70°C to about 90°C, preferably about 80 °C for time duration of
about 10 minutes to about 20 minutes, preferably about 15 minutes. This is followed by
hot washing in acetic acid at a temperature from about 55°C to about 70°C, preferably

about 60°C for time duration of about 5 minutes to about 10 minutes, preferably about 5 minutes. These pre-treatment steps are done in order to get rid of any hydrophobic materials like oil or silicon present in the garment and which can badly affect the oil and water repellent ratings of the garment.
In another embodiment of the present disclosure, the fabric which is initially processed and converted to a hydrophobic material free garment is further subjected to the prepared chemical composition comprising the following constituents: DMDHEU resin, resin catalyst, fluorocarbon, fluorocarbon extender and polyalkyne. Once the prepared chemical composition is sprayed on to the garment using a spraying machine, the garment is dried in a drying machine and thereafter the dried garment is subjected to steam pressing. For the required crease setting and to obtain the desired wrinkle free feel and oil and water repelling property, this treated garment is subjected to curing. The treated garment is further cooled to obtain the oil and water repelling, wrinkle free garment.
In an embodiment of the present disclosure, the resin used in the instant composition is modified dimethylol, dihydroxy, ethylene urea (DMDHEU) as given in figure 1. DMDHEU and modified DMDHEU are compounds which mainly contain N-alkoxymethyl and N-methylol groups as illustrated in figure 1. DMDHEU resins are extensively used in the textile industry. During the (finishing or curing) treatment process the N-methylol compounds react with hydroxyl groups of cellulose, which is the most important reaction in the instant disclosure. Further, they also react among themselves or with reactive NH groups. Thus, this modified resin reduces the formaldehyde release, the value of which is below 75 ppm. In other words, the reaction begins at the time of spraying the garment and finally ends at the curing stage.
In another embodiment of the present disclosure, the resin catalyst used in the instant disclosure is a salt of metal, like MgCl2 which accelerates rate of the reaction between resin and cellulose. Alternatively, MnCl2 is also used. The polyalkyne used in the present disclosure is selected from a group comprising polyethylene or polypropylene. The

polyethylene reacts with cellulose to give better stability in terms of wrinkle recovery and shape of the garment.
In another embodiment of the present disclosure, fluorocarbon is fluorine containing acrylic polymer. The fluorocarbon chemical repellents are unique in that they confer both oil and water repellency to fabrics. The ability of fluoro chemicals to repel oils is related to their low surface energy which depends on the surface of fluorocarbon segments of the molecule, the orientation of fluorocarbon tail, the distribution and amount of fluorocarbon moiety on cellulose.
In another embodiment of the present disclosure, commercial fluoro chemical repellents are fluorine-containing acrylic polymers. This is a convenient method of affixing per fluoro side chains to fibre surfaces that orients air-ward and gives a reasonably close packed surface of -CF2- and -CF3- groups. For example, acrylic acid reacts with perfluoro alcohol to form the corresponding acrylic ester. This aspect is illustrated in the figure 2. The acrylate monomer polymerizes to form a high molecular weight polymer that is converted to an emulsion. The emulsion dries to a continuous film covering the fibre surface. The process of Heating/Curing facilitates the orientation by increasing molecular motion. For maximum repellency, the side chain must have Ten fully fluorinated carbons. The critical surface tension reaches a minimum when the side chain number increases to ten.
In another embodiment of the present disclosure, the fluorocarbon extender is a modified polyurethane specifically a dispersion of polyisocyanate, and improves the wash durability of the fluorocarbons by keeping them intact with cellulose.
In an embodiment of the present disclosure, the resin DMDHEU cross links with the cellulose -OH -bond and due to the extended and permanent (after curing) chain molecules of cellulose, it resists the breaking of chains due to external force and acts to render the wrinkle free property. Further, all the above stated chemicals act simultaneously at the

same time during treatment to result in the final property of wrinkle freeness along with the oil and water repelling property.
In another embodiment of the present disclosure, as the resin used is very high in percentage, the strength loss will be approximately 50-60%. Hence, while choosing the fabric for this specific finish the strength parameters should be taken care of. The minimum tensile strength for warp and weft should be about 35 kg to about 40 kg, and the minimum tear strength should be at the range of about 3200 grams to about 3800 grams for both warp and weft.
In an embodiment of the present disclosure, the Fabric requirement is as follows:
• The treatment can be subjected on any cotton based fabric.
• The fabric that is taken for treatment should be pure finished, i.e it should not contain any finishing material which can make the fabric hydrophobic.
• The water drop absorbency of the fabric should be less than about 5 seconds.
• Lastly, the strength of the fabric should be good enough to sustain the strength drop during the process.
In another embodiment of the present disclosure, by using optimum quantity of DMDHEU resin along with catalyst the present disclosure offers 50 wash sustainability of wrinkle free property on garments. The oil-water repelling property along with the wrinkle free nature will give the garment an extra edge making it safe from outside attack of water and oil based stain till about 50 washes sustainability.
The present disclosure enables uses woven products (Trouser) made of 100% cotton, treated and tested in BVQI singapore. For the instant composition treated garment of the present disclosure, the Durable Press (DP) & Crease Retention (CR) ratings are 4 and 3.5 after 50 washes. The average value after 50 washes is 3.7 as per AATCC143 standards. Similarly, for the water and oil repellency test report is excellent for the treated garment of the instant disclosure. As per AATCC 118 standards the initial oil repellency of the treated garment is 6.5 grade and after 30 washes it is 5 grade. Further, the water repellency

property of the treated garment as per the AATCC 193 standard is 7 grade and after 30 washes it is 6.5 grade. After 50 washes the oil repellency is 4.5 and water repellency is 6 grade.
The examples elaborated below, make use of the applicable terminologies, such as Smoothness appearance (SA), Seam smoothness and the Crease retention (CR), Durable Press Rating (DP), water and oil repellency used by persons skilled in the art to define wrinkle free-oil and water repellent nature of a fabric.
The composition of instant disclosure is synergistic in nature. The composition shows extraordinary activity in obtaining wrinkle free garment. The activity of the composition is well beyond the expectations of the inventors and is also significantly more than the additive effects of the individual components namely DMDHEU resin, resin catalyst, flurocarbon, flurocarbon extender and polyalkyne. Thus, the activity is surprising/ extraordinary, synergistic in nature when combined together and is thus both novel and inventive in nature. Lastly, the Industrial Application of the composition is also well-established. Therefore, the instant composition is a leap forward in the textile industry.
The present disclosure is further described with the help of the following examples and figures. However, these examples should not be construed to limit the scope of the disclosure.
EXAMPLE 1
A treated cotton fabric is taken and converted into a desired garment by industrially known methods. This garment is further subjected to the instant treatment to obtain the desired water and oil repelling wrinkle free effect on the garment.
1. Pre-treatment of the desired garment
The desired garments is pretreated by washing the garment with dispersing and soaping agents like Erional-RN at a temperature from about 70°C to about 90°C, preferably about 80°C for a time duration of about 10 minutes to about 20 minutes, preferably about 15

minutes. Followed by hot washing in acetic acid at a temperature from about 55°C to about 70°C, preferably about 60°C for time duration of about 5 minutes to about 10 minutes, preferably about 5 minutes. This is done to remove all kinds of hydrophobic materials like oil, silicon etc. which affect badly the oil and water repellent ratings of the garment and is also done to make the garment more hydrophilic in nature.
1. Chemical Composition
This above pre-treated garment is taken and treated with the prepared chemical
composition comprising of the following constituents:
Water (about 25°C to about 30°C) : appx:13 ltr
DMDHEU resin : about 9 to about 11%
resin catalyst : about 20 to about 25% of
the concentration of resin.
flurocarbon : about 6 to about 7%
flurocarbon extender : about 1 to about 2%
polyalkyne : about 1 to about 4%
pH : about 5 to about 7
The above mentioned chemical constituents, in the mentioned concentrations when dissolved in water constitute the instant chemical composition.
In an embodiment of the present disclosure, the resin DMDHEU used is about 10% of the total volume of liquid, the resin catalyst is about 25% of resin used, the polyalkyne is about 2%, the flurocarbon is about 6.5% of the total volume of liquid and the Fluorocarbon extender is about 1.5% of the total volume of liquid.
In another embodiment of the present disclosure, the DMDHEU resin is chosen from Resil LFR (Low formaldehyde resin) and Acrofix VLF, the catalyst is selected from a group comprising MgCl2 and MnCl2, the flurocarbon is a Fluoro-acrylic polymer chosen from TG533 and Oilophobol C, the flurocarbon extender is a modified polyurethane and is a

dispersion of polyisocyanate in water and is chosen from Resil WDI (Wash Durable improver) and Hydrophobol XAN and the polyalkyne is selected from a group comprising polyethylene and polypropylene, and is chosen from Ultrafab RTS (Retaining Tear Strength) and Ultrafab CSLF of Resil.
2. Chemical Treatment and drying:
Once the chemical composition is prepared, spraying of the garments (inside out) is done in the spraying machine. The prepared instant composition is sprayed in a closed chamber for a time duration of about 5 minutes to about 15 minutes at a temperature ranging from about 25°C to about 35°C, preferably about 30°C in the rotating spraying machine through pump and sprayer. After about 10 minutes, the sprayed garments are subjected to tumble drying in a drying machine.
3. Steam Pressing of garment:
The next step involves steam pressing of the garment. A steam press, sometimes called a Hoffman press, of the type commonly used for pressing creases (for example imparting center crease in a trouser).
A typical press consists of an upper head and a lower buck which can be brought together to hold fabric under lateral compression while it is steamed. The head is a thinly padded, while the buck is covered with thick padding and is somewhat more resilient than the head. Steam can be introduced through either the head or buck and the buck can be connected to a vacuum pump.
The pressing operation consists of three basic steps:
a. The garment is compressed between the head and the buck and steam is passed through
the fabric, usually from head to buck (steaming cycle).
b. The steam is turned off while the press remains closed (baking cycle).
c. A vacuum is applied to the buck as the press is opened and the fabric is cooled by
drawing ambient air through it (vacuum cycle). Cycles may vary from a few seconds up to
one minute’s duration. A typical procedure is about 8- about 10 seconds steam, about 6 -

about 10 seconds bake and about 4- about 10 seconds vacuum. The process has a number of variables that are thought to contribute to its effectiveness:
• the temperature and relative humidity of the steam,
• the temperature of the buck,
• the thickness of the buck padding,
• the vacuum pressure,
• the steaming, baking and vacuuming times,
• the mechanical pressure between the head and the buck,
• the regain of the fabric.
4. Curing:
After steam pressing, the garments (as trousers) are subjected to curing for crease setting. Further, the garments are exposed to high temp in a closed chamber to get the water and oil repelling-wrinkle free effect in the cotton fabric of the garment. In the curing process the temperature is an important factor, wherein the best temperature range is found to be about 155°C to about 165°C, preferably about 160°C for time duration of about 10 minutes to about 15 minutes, preferably about 12 minutes. Once curing is completed, the cotton garments are subjected to cooling to obtain the oil and water repelling wrinkle free garments.
EXAMPLE 2
The following protocol is applicable in case of fabric which is not treated. Therefore initially the raw cotton fabric is subjected to a series of treatments that are conventionally available for treatment of fabrics briefly outlined below:
The fabric processing involves: singing, desizing, scouring, bleaching, mercerization, Fabric dyeing, finishing (without silicons and adding only suebility softer) and finally sanforising.
The fabric is then converted into a garment by conventionally known industrial methods and is subjected to the same treatment as described in Example 1, wherein the garment is

first pre-treated, then treated with the prepared chemical composition by spraying it inside out in a spraying machine. After 10 minutes, the garment is tumble dried in a drying machine.
The garment then undergoes steam pressing using the Hoffman press for imparting crease into the garment. The next step involves curing of the garment for crease setting in order to achieve the complete water and oil repelling-wrinkle free effect of the cotton garment and to obtain the ready to use garment.
EXAMPLE 3
The treated garment is checked for oil and water repellency using standard tests; the oil repellency test method is AATCC-118 and the water repellency test method is AATCC-193.
The oil repellency method is used to detect the presence of fluoro-chemicals or other compounds capable of imparting a low energy surface, on all types of fabric. This is done by evaluating the fabric resistance to wetting by selected series of liquid hydrocarbons of different surface tension.
Here, drops of standard test liquids consisting of a selected series of hydrocarbons with varying surface tensions are placed on the fabric surface and observed for wetting, wicking and contact angle. The oil repellency grade is the highest numbered in the test liquid which does not wet the fabric surface.
Similarly, the water /alcohol repellency is used to determine the efficiency of a protective finish that is capable of imparting a low energy surface on all types of fabric. This is done by evaluating the fabric resistance to wetting by a selected series of water /alcohol solutions of different surface tension by placing them on the fabric surface and observing for wetting, wicking and contact angle. The water/alcohol resistance grade is the highest numbered in the test liquid which does not wet the fabric surface.

A treated cotton fabric which is converted into a desired garment is checked for the above properties after the garment is subjected to the treatment with the instant chemical composition as depicted in example 1.
EXAMPLE 4
Laboratory tests are conducted on various cotton fabrics, wherein the treated fabric is converted into a desired garment, thereafter pre-treated using the dispersing and soaping agents and then subjected to the prepared instant composition comprising the following constituents in their specific concentrations. The chemical composition comprises of DMDHEU resin, resin catalyst, fluorocarbon, fluorocarbon extender and polyalkyne dissolved in distilled water.
The DMDHEU resin used in this example is Resil LFR, the resin catalyst used is MgCl2, fluorocarbon used is TG533, whereas the flurocarbon extender used is Resil WDI and the polyalkyne added is ultrafab RTS, a polyethylene. The pH of the chemical composition is maintained at a range from about 5 to about 7. The relative concentrations of the constituents used are represented in Table 1 below. The pre-treated cotton garment is sprayed inside out, with the chemical composition solution comprising the above mentioned constituents in their respective concentrations for 10 minutes and then tumble dried in a drying machine. The chemical treatment and drying of the garment is followed by the process of steam pressing using a Hoffman press (for example imparting center crease in a trouser, as mentioned in example 1) and thereafter curing for crease setting (as mentioned in the example 1). The garment is then tested for the specified parameters required to confirm the water and oil repelling wrinkle free nature of the garment. The various parameters taken into account for testing the garment’s wrinkle free nature are: Durable Press rating and the Crease retention rating.
Further more, apart from the specific constituents used above the DMDHEU resin can also be Acrofix VLF, the catalyst MnCl2, the flurocarbon Oilophobol C, the flurocarbon extender Hydrophobol XAN and the polyalkyne, Ultrafab CSLF of Resil.

Crease retention (CR): The visual impression of an inserted crease quantified by
comparison with a set of reference standards.
Durable Press (DP): The ability to retain substantially the initial shape, flat seams, pressed
in crease and unwrinkled appearance during use and after laundering or dry-cleaning.
Oil and water repellency: Drops of standard test liquids consisting of selected series of
hydrocarbons with varying surface tensions, are placed on the fabric surface and observed
for wetting, wicking and contact angle, the oil repellency grade is the highest numbered
test liquid which does not wet the fabric surface.
Drops of selected series of water/alcohol solution of different surface tension are placed on
fabric surface and observed for wetting, wicking and contact angle. The water repellency
grade is the highest numbered liquid which does not wet the fabric surface.
The Visual standards, CR and DP are available at a rating of 1 to 5, wherein 1 is the lowest and 5 is the highest rating and the oil and water repellency rating is available at a rating of 1 to 8, wherein 1 is the lowest and 8 is the highest.
The constituents and their respective concentrations are defined in table 1 below:
Table 1

CHEMICAL CONSTITUENTS TRADE NAME USED CONCENTRATION
DMDHEU resin Resil LFR 10%
resin catalyst MgCl2 2.5%
flurocarbon TG533 6.5%
flurocarbon extender Resil WDI 1.5%
polyalkyne-polyethylene ultrafab RTS 2%
Normal Water (about 25°C to about 30°C) Approx. 13 Litres
The percentages mentioned above are based on total volume of liquids. The testing of the cotton garment for the effectiveness of the present treatment is done in such a way that the efficiency of the treatment is checked after one wash and ten washes. The machine wash is

conducted for 12 minutes, at a temperature of about 41°C in 18 gallon of the water with standard detergent, followed by Tumble drying of the garment. The treatment is carried out as mentioned in example 1 and tested as provided in example 3.
The test results obtained are based on the parameters chosen as indications for determining the wrinkle free nature of the garment. These ratings of the parameters are tested over a scale of 1 to 5, wherein the rating of 4 provided for the high performing parameter and the lowest performing parameter attained a rating of 1. If a garment showed the value as 4 for all the parameters tested, then along with the soft hand feel and bounciness of the garment put together, it could be determined whether the treatment has been completely effective or not, and hence concluded if the garment has become permanently wrinkle free in nature.
With respect to the present example, the garment showed a Durable Press rating of 4 and the Crease retention rating of 3..5, after fifty washes of home laundering as per the AATCC-143 standards. Further, the initial oil repellency is 6.5 as per the AATCC-118 standards and initial water repellency of 7 as per AATCC-193 standards. The method followed to check the water and oil repellency is similar to the method provided in example 3. Hence, in the instant example, the treated garment depicts excellent water and oil repellency. Moreover, the treated garment has the desired hand feel and bounciness expected to establish it as wrinkle free in nature and is found to be maintaining the same parameters ratings even after 50 washes.
EXAMPLE 5
In another set of similar experiments, tests are conducted with the pre-treated garment, wherein the concentrations are varied to determine the most optimum and the most suitable working concentration ranges of the constituents. The instant chemical composition’s constituents are the same as mentioned in the previous example with a difference in the concentrations used, as elaborated in table 2 below. Specifically, the concentration of the DMDHEU resin is modified as represented in the table 2 below, while the concentration of the rest of the constituents remained the same. The DMDHEU resin used in this example is Resil LFR, the resin catalyst used is MgCl2, Fluorocarbon used is

TG533, whereas the flurocarbon extender used is Resil WDI and the polyalkyne added is ultrafab RTS, a polyethylene. The pH of the chemical composition is maintained at a range from about 5 to about 7. The relative concentrations of the constituents used are represented in Table 2 below.
Further more, apart from the specific constituents used above the DMDHEU resin can also comprise of Acrofix VLF, the catalyst MnCl2, the flurocarbon Oilophobol C, the flurocarbon extender Hydrophobol XAN and the polyalkyne Ultrafab CSLF of Resil.
The constituents and their respective concentrations are defined in table 2 below:
Table 2

CHEMICAL CONSTITUENTS TRADE NAME USED CONCENTRATION
DMDHEU resin Resil LFR 9.0%
resin catalyst MgCl2 2.5%
flurocarbon TG533 6.5%
flurocarbon extender Resil WDI 1.5%
polyalkyne-polyethylene ultrafab RTS 2%
Normal Water (about 25°C to about 30°C) Approx. 13 Litres
The percentages mentioned are based on total volume of liquids. The testing of the cotton garment for the effectiveness of the present treatment is done in such a way that the efficiency of the treatment is checked after one wash and fifty washes. The machine wash is conducted for 12 minutes, at a temperature of about 41°C in 18 gallon of water with standard detergent, followed by Tumble drying of the garment. The treatment is carried out as mentioned in example 1 and tested as provided in example 3.
With respect to the present example, the garment showed a Durable Press rating of 4 and the Crease retention rating of 3.5, after fifty washes of home laundering as per the AATCC-143 standards. Further, the initial oil repellency is 6.5 as per the AATCC-118 standards and initial water repellency is7 as per AATCC-193 standards. The method

followed to check the water and oil repellency is similar to the method provided in example 3. Hence, in the instant example, the treated garment depicts excellent water and oil repellency. Moreover, the treated garment has the desired hand feel and bounciness expected to establish it as wrinkle free in nature and is found to be maintaining the same parameters ratings even after 50 washes. Hence, it can be derived that the concentration of resin used in the instant example, works well in the concentration range of about 9% to about 11%.
EXAMPLE 6
Another experiment is conducted on similar lines, by changing the concentration values of the constituents. The concentration of the resin catalyst is modified as represented in table 3 below, while the concentration of rest of the constituents remained the same. The DMDHEU resin used in this example is Resil LFR, the resin catalyst used is MgCl2, Fluorocarbon used is TG533, whereas the flurocarbon extender used is Resil WDI and the polyalkyne added is ultrafab RTS, a polyethylene. The pH of the chemical composition is maintained at a range from about 5 to about 7. The relative concentrations of the constituents used are represented in Table 3 below.
Further more, apart from the specific constituents used below the DMDHEU resin can also comprise of Acrofix VLF, the catalyst MnCl2, the flurocarbon Oilophobol C, the flurocarbon extender Hydrophobol XAN and the polyalkyne Ultrafab CSLF of Resil.
The constituents and their respective concentrations are defined in table 3 below:

polyethylene
Normal Water (about 25°C to about 30°C) Approx. 13 Litres
The garment is sprayed inside out with the liquor solution, followed by drying and subjected to further treatments. The treatment is carried out as mentioned in example 1 and tested as provided in example 3. The testing is done on similar parameter lines as those mentioned in the previous examples and hence the garment is washed in a solution containing said the chemical composition. To check the efficiency of the composition, the garment is tested for the same parameters after more than one wash, specifically after fifty washes and the results obtained are recorded.
The results obtained confirmed that the working concentration range is 20-25% the concentration of the resin and the resin catalyst is effective at the said concentration level of 1.00%. The garment is seen to depict a Durable press rating of 3 and Crease retention rating of 3, after the first wash and fifty washes. Further, the initial oil repellency is 6.5 and initial water repellency is 7. Hence, the range of 20-25% the concentration of total resin used as mentioned above is the most workable range of the resin catalyst that would bring about effective wrinkle free nature of the garment.
EXAMPLE 7
In another set of experiments, the concentration of the fluorocarbon and the fluorocarbon extender is modified to determine the efficiency of the chemical composition of the present disclosure. The constituents used in this example are depicted below. The DMDHEU resin used in this example is Resil LFR, the resin catalyst used is MgCl2, Fluorocarbon used is TG533, whereas the flurocarbon extender used is Resil WDI and the polyalkyne added is ultrafab RTS, a polyethylene. The pH of the chemical composition is maintained at a range from about 5 to about 7. The relative concentrations of the constituents used are represented in Table 4 below. Further more, apart from the specific constituents used below the DMDHEU resin can also comprise of Acrofix VLF, the

catalyst MnCl2, the flurocarbon Oilophobol C, the fluorocarbon extender Hydrophobol XAN and the polyalkyne Ultrafab CSLF of Resil.
The constituents and their respective concentrations are defined in table 4 below:

Normal Water (about 25°C to about 30°C) Approx. 13 Litres
The composition used in the present example is such that the fluorocarbon used is TG533 but at a varied concentration value of 7% and the fluorocarbon extender has a concentration of 2%, together with the other constituents of the composition. The garment is sprayed with the chemical composition for 10 minutes and then dried and subjected to further treatments. The dried garment is then taken for steam pressing followed by curing to set the crease to obtain the garment which is ready to be dried and thereafter tested. The treatment is carried out as mentioned in example 1 and tested as provided in example 3.The garment so treated in tested on the various parameters like Durable Press rating and the Crease retention. The results obtained are recorded such that the garment is tested after fifty washes. The Durable press rating and the Crease Retention is found to have a value of 4 , and moreover the hand feel and the bounciness of the garment are seen to be excellent even after completion of fifty washes. The oil and water repelling property of the garment is found to be 4.5 and 6 after 50 washes. Hence, it can be established that the garment is able to retain the wrinkle free nature along with the oil and water repelling property permanently and is not restricted only to a single wash. Hence, the most workable range

for the fluorocarbon and fluorocarbon extender is about 6% to about 7% and about 1% to about 2%.
EXAMPLE 8
Experimentation is also done to determine the effect of change in concentration value of polyalkyne on the oil and water repellent property and wrinkle free nature of the garment. The pre-treated garment is sprayed with the chemical composition such that the resin is Resil LFR, along with catalyst MgCl2, the flurocarbon as TG533, the flurocarbon extender is Resil WDI and the polyalkyne is Ultrafab RTS. The respective concentrations of the constituents are represented in table 5 below. However the concentration of polyalkyne is different and is 3%.
Further more, apart from the specific constituents used below the DMDHEU resin can also comprise of Acrofix VLF, the catalyst MnCl2, the flurocarbon Oilophobol C, the flurocarbon extender Hydrophobol XAN and the polyalkyne Ultrafab CSLF of Resil.
The constituents and their respective concentrations are defined in table 5 below:

Normal Water (about 25°C to about 30°C) Approx. 13 Litres
As mentioned in the previous example the chemical composition is hence sprayed on the garment and this is dried, and steam pressed and cured for crease setting. The tests are

conducted based on the same parameters used in the previous examples. The tests are done after a single wash and after fifty washes. However the results are found to be the same at every stage of the testing. The Durable press rating and the Crease Retention are found to have a value of 4 and 3.5. Further, the oil and water repelling property is found to be 4.5 and 6 after 50 wash. Hence, the wrinkle free effect and oil and water repellent property is found to be permanent and as desired.
EXAMPLE 9
Similar experimentation is also conducted to determine the effect of change in concentration value of DMDHEU resin and resin catalyst on the oil and water repelling and wrinkle free nature property of the garment. This is done in such a way that the pre-treated garment is sprayed with the instant chemical composition. However, the concentration value of the resin used is higher than the concentration values tested in the above examples and mentioned in the effective range for this disclosure. Further, the concentration of the resin catalyst used is also lower than the catalyst concentration’s mentioned in the previous examples, specifically it is 1.00%.
The DMDHEU resin used in this example is Resil LFR, the resin catalyst used is MgCl2, Fluorocarbon used is TG533, whereas the fluorocarbon extender used is Resil WDI and the polyalkyne added is ultrafab RTS, a polyethylene. The pH of the chemical composition is maintained at a range from about 5 to about 7. The relative concentrations of the constituents used are represented in Table 6 below.
Further more, apart from the specific constituents used below the DMDHEU resin can also comprise of Acrofix VLF, the catalyst MnCl2, the flurocarbon Oilophobol C, the fluorocarbon extender Hydrophobol XAN and the polyalkyne Ultrafab CSLF of Resil.
The constituents and their respective concentrations are defined in table 6 below:
Table 6

DMDHEU resin Resil LFR 13.00%
resin catalyst MgCl2 1%
flurocarbon TG533 6.5%
flurocarbon extender Resil WDI 1.5%
polyalkyne-polyethylene ultrafab RTS 2%
Normal Water (about 25°C to about 30°C) Approx. 13 Litres
The chemical treatment is followed by the drying procedure, steam pressing and curing for crease retention. The garment is tested for 30 Machine washes and the results recorded. The Durable press rating and the Crease Retention are seen to produce the rating of 4 for both the parameters and the oil and water repellency rate is 5.5 and 6.5 after 30 wash. However, in the high resin concentration testing condition, after 30 washes the fabric got damaged due to the high percentage of resin, which makes the fabric loose its strength. Hence, these concentration values do not depict the desired wrinkle free nature and are not included in the range. It also establishes that the synergistic effect is depicted by the constituents when they are present at the specific concentration ranges and only at those respective concentration values the desired wrinkle freeness and oil and water repelling property is observed.
EXAMPLE 10
In another set of similar experiments, tests are conducted with the pre-treated cotton fabric converted into a desired garment, wherein the concentrations are varied to determine the most optimum and the most suitable working concentration ranges of the constituents. The chemical composition’s constituents are the same as mentioned in the previous example with a difference in the concentrations of fluorocarbon and fluorocarbon extender used, as elaborated in table 7 below.
The DMDHEU resin used in this example is Resil LFR, the resin catalyst used is MgCl2, Fluorocarbon used is TG533, whereas the fluorocarbon extender used is Resil WDI and

the polyalkyne added is ultrafab RTS, a polyethylene. The pH of the chemical composition is maintained at a range from about 5 to about 7. Further more, apart from the specific constituents used below the DMDHEU resin can also comprise of Acrofix VLF, the catalyst MnCl2, the flurocarbon Oilophobol C, the fluorocarbon extender Hydrophobol XAN and the polyalkyne Ultrafab CSLF of Resil.
The constituents and their respective concentrations are defined in table 7 below:
Table 7

CHEMICAL CONSTITUENTS TRADE NAME USED CONCENTRATION
DMDHEU resin Resil LFR 10%
resin catalyst MgCl2 2.5%

polyalkyne-polyethylene ultrafab RTS 2%
Normal Water (about 25°C to about 30°C) Approx. 13 Litres
The prepared instant chemical solution comprising the said constituents is sprayed on the pre-treated garment. The sprayed garment is subjected to further treatment of drying, steam pressing and curing for crease setting. The dried garment is then tested for the same parameters as those mentioned in the previous example for confirming the wrinkle free nature and oil and water repelling property of the garment. The treatment is carried out as mentioned in example 1 and tested as provided in example 3.The tests varied with change of the concentration value with respect to the fluorocarbon and fluorocarbon extender being used. Specifically, when the concentration value of the fluorocarbon used is 3% and the concentration of the fluorocarbon extender is within the desired concentration range (1%). Then, the results are found to be dis satisfactory in terms of the oil and water repelling property expected. The treated garment showed Durable press rating of 4.0 and

the Crease retention rating of 3.5 and the oil and water repelling rating of 4 and 5.0 after fiftieth wash.
When the concentration value of the fluorocarbon used is 3% and the concentration of the fluorocarbon extender is lower 0.5%. Then, the treated garment showed Durable press rating of 4.0 and the Crease retention rating of 4 and the initial oil and water repelling rating of 6.5 and 7.0. But the oil and water repelling rating reduced to 4.0 after the thirty washes respectively. Hence, it can be firmly concluded that the said concentration values used in this particular example are not efficient in bringing about the complete wrinkle free effect and the oil and water repelling property in the garment. Further, the fluorocarbon concentrations in the mentioned range of about 6% to about 7% and the fluorocarbon extender concentration of about 1% to about 2% are seen to bring about the best results in terms of the wrinkle free effect as well as the oil and water repelling property of the treated cotton garment.
EXAMPLE 11
In another set of experiments, the concentration of the polyalkyne is modified to determine the efficiency of the chemical composition of the present disclosure. The chemical composition’s constituents are the same as mentioned in the previous example with a difference in the concentrations of polyalkyne used, as elaborated in table 8 below.
The DMDHEU resin used in this example is Resil LFR, the resin catalyst used is MgCl2, Fluorocarbon used is TG533, whereas the flurocarbon extender used is Resil WDI and the polyalkyne added is ultrafab RTS, a polyethylene. The pH of the chemical composition is maintained at a range from about 5 to about 7. Further more, apart from the specific constituents used below the DMDHEU resin can also comprise of Acrofix VLF, the catalyst MnCl2, the flurocarbon Oilophobol C, the flurocarbon extender Hydrophobol XAN and the polyalkyne Ultrafab CSLF of Resil.
The constituents and their respective concentrations are defined in table 8 below:
Table 8

CHEMICAL CONSTITUENTS TRADE NAME USED CONCENTRATION
DMDHEU resin Resil LFR 10%
resin catalyst MgCl2 2.5%
flurocarbon TG533 6.5%
flurocarbon extender Resil WDI 1.5 %
polyalkyne-polyethylene ultrafab RTS 0.5%
Normal Water (about 25°C to about 30°C) Approx. 13 Litres
The garment is sprayed with the chemical composition for 10 minutes and then dried and subjected to further treatments. The dried garment is then taken for steam pressing followed by curing to set the crease and obtain the garment which is ready to be dried and thereafter tested. The garment so treated in tested on the various parameters like Smoothness appearance, Seam smoothness and the Crease retention. The results obtained are recorded such that the garment is tested after a single wash and fifty washes. The Durable press rating and the Crease Retention is found to have a value of 4 and 3.25, and the initial oil and water repelling property is found to be 6.5 and 7.0. Hence, it can be derived that the decrease in the concentration of the polyalkyne depicts a proportional decrease in the CR rating and it can be established that the garment is not able to depict the desired level of wrinkle free nature. Therefore, the concentration value of polyalkyne used in this example cannot be included in the range and the instant concentration range of about 2% to about 4% is the most workable concentration range for polyalkyne.
Hence, from the above examples it can be concluded that the said chemical preparation is most effective in the said concentration ranges and with the specified constituents. The synergistic effect of the chemical constituents brings about the wrinkle free effect and the oil and water repelling property of the cotton garment. The instant synergistic composition comprises of the DMDHEU resin, chosen from Resil LFR (Low formaldehyde resin) and Acrofix VLF and with a concentration ranging from about 9% to about 11%, the resin

catalyst is selected from a group comprising MgCl2 and MnCl2, with a concentration ranging from about 20% to about 25% of the concentration of the resin, the flurocarbon is a Fluoro-acrylic polymer chosen from TG533 and Oilophobol C, with a concentration ranging from about 6% to about 7%, the flurocarbon extender is a modified polyurethane and is a dispersion of polyisocyanate in water and is chosen from Resil WDI (Wash Durable improver) and Hydrophobol XAN, with a concentration ranging from about 1% to about 2% and the polyalkyne is selected from a group comprising polyethylene and polypropylene, and is chosen from Ultrafab RTS (Retaining Tear Strength) and Ultrafab CSLF of Resil, with a concentration ranging from about 2% to about 4%.
