4. DESCRIPTION:
Technical Field of the Invention
[0001] The subject matter of the present invention is directed towards a method of manufacturing melange textile. The present invention more particularly relates to a method of producing woven or knitted fabrics or garments with differential dyeing properties.
Background of the Invention
[0002] Conventional dyeing methods consists of certain shortcomings in commercial sense. Frequently faced shortcomings in the conventional dyeing methods include availability of textiles dyed in limited colors and in limited shades in any given pattern or style.
[0003] Yet another problem is, some conventionally dyed fabrics frequently undergo discoloration during washing if the dyes are not penetrated into the fibers through a sufficiently strong bond. The unbound dyes migrate during the wash. They may go on to other textiles and stain them. Further to this, these unbound dyes and stabilizing salts are released into aquatic bodies, thus contributing to water pollution and other environmental hazards.
[0004] Furthermore, the conventional textile coloring and shading processes are complex. Most of these methods involve using yarns of various colors produced from dyeing of yarn packages in pre-defined colors. So, the colors and patterns of textiles are quite a limited option for the fabric or garment manufacturer. In order to achieve multiple color effects, the fabric is knitted or woven either with pre-dyed yarns or with different types of yarns or with combinations thereof. The fabric is dyed with one or more dye stuffs in single or several dying steps.
[0005] In the manufacturing of traditional melange, the constituent fibers are dyed using a direct dye or fiber reactive dyes in different colors and are mixed with un-dyed fibers and they are spun to make the composite color yams, making melange or heather yarns used in weaving or knitting fabrics and garments.. This is rather a complex and time consuming process.
[0006] It is appreciated to design a process for manufacturing textiles having a heather or a melange look, wherein the process offers a complete flexibility in color selection, short lead-times, no limitations for special color shades, no surplus inventory of melange yarn and reduced time lapsed in producing textiles in seasonal colors even in small lots. Hence, it is an objective of the invention to replace the conventional melange yarns with cationic melange yarns in an effective method for manufacturing melange fabrics.

[0034] Referring to FIG.l is a flow diagram 100 illustrating a method of manufacturing the melange textile, in accordance with an exemplary embodiment of the present invention. The method of manufacturing the melange textile starts at step 102 depicting the selection a cellulose fiber material in a pre-determined ratio. The cellulose fiber material preferably includes a natural cellulose fiber, a re-generated cellulose fiber and a combination of the natural cellulose fiber and the re-generated cellulose fiber.
[0035] According to an exemplary aspect of the present invention, the natural fiber includes cotton, linen and the likes. The re-generated fibers include a viscose, rayon, modal and the like. Particularly, the cotton fibers having a prerequisite fiber length are used for the purpose of the invention, for example the cotton fiber ideally has a length of 10 mm to 65 mm.
[0036] In accordance with a non limiting exemplary aspect of the present invention, the regenerated cellulose fibers are from viscose, rayon and modal. Particularly, fibers having a prerequisite fiber length of about 10 mm to 65 mm in length.
[0037] From step 102, the flow diagram 100 continues with step 104 which describes about counter ionizing or cationizing the cellulose fiber material including a pre-determined percentage cationic concentration from 1% to 100%. The counter ionization or cationization is a method of introducing cationic reactive sites on to the surface of cotton cellulose fibers with anionic carboxyl groups.
[0038] In a preferred embodiment of the present invention, the counter ionization process of a selected batch of fiber is accomplished in a cationic reaction bath with a suitable cationizingn agent. The cationizing agent is a quaternary ammonium compound preferably includes a N (3- chloro-2-hydroxypropyl)-trimethylammonium chloride. More particularly, a trimethylammonium chloride is used in a pre-determined quantity or concentration ranging from 1% to 100%.
[0039] From step 104, the flow diagram 100 continues with step 106 which describes about processing the cationized fibers having different percentage cationic concentration ranging from 1% to 100%, wherein the processing refers to a cationized yarn preparation. According to an exemplary aspect of the present invention, the resultant cationized fibers are mixed or blended with un-treated fibers in any pre-determined ratio ranging from 1% to 99% for the manufacture of different cationic yarns with different cationic percentage strengths. The fibers used for blending comprises at least one of a natural cellulose fiber, a re-generated cellulose fiber and combination of natural and re-generated cellulose fiber. Where the at least one natural fiber is cotton or linen and the likes. The re-generated cellulose fiber includes one of a viscose, rayon, modal and the likes.
[0040] From step 106, the flow diagram 100 continues with step 108 which describes about the cationic fiber blends made into yarns of pre-determined count range. The cationic yarn can be spun using any available techniques which can be used for producing yarn. Typically, the yarn count ranges from Ne 2's to 140's and the invention can be achieved with any cationized yarn with a count range from Ne 2's to 140's and falls with in the scope of the invention.
[0041] From step 108, the flow diagram 100 continues with step 110, where multiple grades of cationized yarn are subjected to a pre-defined pattern of weaving or knitting fabrics or garments with differential dye ability. In one exemplary aspect of the present invention, the cationized yarn of pre-determined percentage cationic concentration is weaved with yarns of different cationic percentage or with un-cationized yarn in a pre-defined pattern. A warp made of either different grades of cationized yarn or un cationized yarn is weaved with a weft made of yarn either cationized yarn or a predominant proportion of un-cationized yarn in a manner such that the weave has pre-defined number of intermingling points per meter of the fabric and in a predetermined pattern. Any pre-defined pattern like stripes can be achieved on the knitted fabric by knitting the cationized yarn along with different yarns of different cationic percentage strength or by knitting the cationized yarn along with un-treated yarn and yarn of different cationic percentage strength to obtain stripes.
[0042] From step 110, the flow diagram 100 ends with step 112 which depicts the formation of melange textile either woven or knitted with differential dye ability.
[0043] Referring to FIG.2 is a flow diagram 200 illustrating the process of melange dyeing. From step 200, the flow diagram 200 starts with the step 202, this describes about washing the grey or pre-treated fabrics or garments with differential dye ability in a bath containing wetting agent. This is particularly done to improve the wet pick up or to increase the absorption rate of the fabric or garments during dyeing. The term pre-treated fabric includes the differentially dyeing fabric or garment either scoured or bleached.
[0044] From step 202, the flow diagram 200 continues with step 204 which illustrates the process of melange dyeing. In one exemplary aspect of the present invention, the fabric weave or fabric knit is first dyed in a dye bath which is free of salt and alkali and containing a dye solution having a pre-defined concentration of anionic dye of any pre-defined colours. In accordance with a non limiting exemplary aspect, the dyeing process involves dissolving a reactive anionic dye, taken in a weight ratio ranging from upto 1% to 2% of the total cationic sites on the fabric of the entire fabric, i.e. calculating the amount of dye stuff only to the cationic portions on the entire fabric which also contains non-cationic portions and not to the entire fabric. The at least one reactive dye or a direct dye is dissolved in water to make a dye bath which is relatively free of any salt and alkali comprising water to fabric ratio ranging from upto 1:10 to 1:30. The dyeing process is carried out in a salt and alkali free medium at the room temperature for about upto 20 minutes to 30 minutes. The melange textile with differential dye ability includes the cationic yarn, which contains positively charged cellulose fibers blended with un-treated fibers, which on dyeing attracts the dyes from the dye bath. The un-treated cellulose fibers don't attract dyes because of the absence of the salt and alkali in the dye bath thus giving a heather or melange look to the knitted or woven fabric or garment. Preferably fabric reactive dyes can be used for the purpose of dyeing the cationized fabric.
[0045] From step 204, the flow diagram 200 continues with step 206 where the temperature of the dye bath which is at room temperature is gradually raised about upto 60 degree Celsius to 70 degree Celsius at the rate of increase upto 2 degree Celsius per minute. The dyeing is carried out further for about upto 40 minutes to 50 minutes in a salt and alkali free medium.
[0046] From step 206, the flow diagram 200 continues with step 208, where the excess dye from the dye bath is drained out and the excess dye from the fabric or garment is removed in the hot water washing process followed by a cold water washing process. The multi pattern mélange textile is then washed with a soaping agent or washing agent or leveling agent to finally remove the un-attached dye molecules and get the fabrics or garments done ahead for finishing.
[0047] From step 208, the flow diagram 200 continues with step 210 which describes about finally obtaining the melange textile of different dyeability in different colors. The melange textile in different colors is obtained from the step of dyeing cationized fabric weaves and fabric knits from different grades of cationic yarn in a specified pattern. Often, the pattern on the cationized fabric, colors and shades of the melange textile can be in a manner as specified by a customer.
[0048] From step 210, the flow diagram 200 ends with step 212 which describes about a preferred embodiment of the melange fabrics or garments made from said melange textile woven or knitted in any colours.
[0049] Referring to FIG.3 is a flow diagram 300 illustrating the different methods or types available to process the melange dyeing. From step 300, the flow diagram 300 starts with the step 302 which describes about the manufacture of cationic yarn with different cationic percentage strength, with the yarns made from at least one of a natural cellulose fiber of predetermined fiber length or a re-generated cellulose fiber of pre-determined length or a combination of both natural and re-generated cellulose fiber in any blend ratio from 1 % to 99% and with pre-determined cationic concentration ranging from 1% to 100%. The natural cellulose fiber of pre-determined fiber length is selected from at least one of a cotton fiber, a linen fiber and the likes. The cotton fiber includes a length of about 10 mm to about 65 mm. The regenerated cellulose fiber of pre-determined length is selected from at least one of a viscose fiber, a rayon fiber and a modal fiber and the likes. The viscose fiber includes a length of about or from 10 mm to 65 mm. The cationic yarn includes a count range of Ne 2's to Ne 140s' in single or plied form.
[0050] From step 302, the flow diagram 300 continues with the step 304 and 306 which describes about weaving and knitting of the cationic yarns in any pre-defined pattern. The cationized yarn of pre-determined percentage cationic concentration is weaved with yarns different cationic percentage or with un-cationized yarn in a pre-defined pattern. A warp made of either different grades of cationized yarn or un cationized yarn is weaved with a weft made of yarn either cationized yarn or a predominant proportion of un-cationized yarn in a manner such that the weave has pre-defined number of intermingling points per meter of the fabric and in a pre-determined pattern. Any pre-defined pattern like stripes can be achieved on the knitted fabric by knitting the cationized yarn along with different yarns of different cationic percentage strength or by knitting the cationized yarn along with un-treated yarn and yarn of different cationic percentage strength to obtain stripes.
[0051] From step 304 and 306, the flow diagram 300 continues with the step 308, 310 and 312, 314 which illustrates about fabric and garments made from woven and knitted fabrics with differential dyeability. Once after weaving and knitting is completed, the end product can be taken in the resulting form of fabric or as in the form of garments made from the fabrics, depending on the end use for further process.
[0052] From step 308, 310, 312 and 314, the flow diagram 300 can be continued to the step 316 and 320 or to step 318 and 322. Here, step 316 and 320 illustrates the pre-treatment of the fabric and garments before melange dyeing process. Step 318 and 322 illustrates the process of dyeing the fabric or garment in grey form itself without any prior pre-treatment process. Here, the pre-treatment process includes scouring or RFD (Ready for dyeing) and bleaching of fabrics or garments.
[0053] From step 316 and 320, the flow diagram 300 continues to the step 324 where the pre-treated fabric or garment is dyed in the melange dyeing process. The fabric weave or fabric knit is first dyed in a dye bath which is free of salt and alkali and containing a reactive dye or a direct dye having a pre-defined concentration of anionic dye of any pre-defined colours. The dyeing process involves dissolving a reactive anionic dye, taken in a weight ratio ranging from upto 1% to 2% of the total cationic sites on the fabric of the entire fabric, i.e. calculating the amount of dye stuff only to the cationic portions on the entire fabric and not to the entire fabric which also contains non-cationic portions. The at least one reactive dye or direct dye is dissolved in water to make a dye bath which is relatively free of any salt and alkali comprising water to fabric ratio ranging from upto 1:10 to 1:30. The dyeing process is carried out in a salt and alkali free medium at the room temperature for about upto 20 minutes to 30 minutes. The temperature of the dye bath which is at room temperature is gradually raised about upto 60 degree Celsius to 70 degree Celsius at the rate of increase upto 2 degree Celsius per minute. The dyeing is carried out further for about upto 40 minutes to 50 minutes in a salt and alkali free medium. The melange textile with differential dye ability includes the cationic yarn, which contains positively charged cellulose fibers blended with un-treated fibers, which on dyeing attracts the dyes from the dye bath. The un-treated cellulose fibers don't attract dyes because of the absence of the salt and alkali in the dye bath thus giving a heather or melange look to the knitted or woven fabric or garment. Preferably fabric reactive dyes or direct dyes can be used for the purpose of dyeing the cationized fabric. The excess dye from the dye bath is drained out and the excess dye from the fabric or garment is removed in the hot water washing process followed by a cold water washing process. The multi pattern melange textile is then washed with a soaping agent or washing agent or leveling agent to finally remove the un-attached dye molecules and get the fabrics or garments done ahead for finishing and finally obtaining the melange textile of different dyeability in different colors. The melange textile in different colors is obtained from the step of dyeing cationized fabric weaves and fabric knits from different grades of cationic yarn in a specified pattern. Often, the pattern on the cationized fabric, colors and shades of the melange textile can be in a manner as specified by a customer.
[0054] From step 318, step 322 and step 324, the flow diagram 300 ends with the step 326 which describes about the different types of melange dyeing for differentially dyeing woven and knitted melange fabrics and garments.
[0055] While specific embodiments of the invention have been shown and described in detail to illustrate the inventive principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
