[0047] The present invention discloses a method of manufacturing a non-woven fabric. Fig. 1 illustrates a method (100) that comprises of melting granules of thermoplastic polymer to form a molten polymer (102), forming a web from a molten polymer (104), calendaring the web at a predetermined temperature and a predetermined bonding area bonding to form a bonded web (106), impregnating the bonded web with an organic botanical extract solution developed using an organic botanical extract solution (108), wherein the organic botanical extract solution in the impregnated nonwoven is in a range of 0.5-10% and drying the impregnated bonded web to form the non-woven fabric (110), drying the fabric (112) and slitting the fabric (114).
[0048] At step (102), the polypropylene granules are to be taken as raw material in a range of 25-100 MFI for spun bond fibers and 1000-1800 MFI for melt-blown fibers. The MFI is the melt flow index of the polymer.
[0049] At step (104), the web formation from spun bond beams and melt flow beams: Web formation from Spun bond beams (min. 2 and max. 3 beams) and Melt flow beams (min. 2 and max. 3 beams), such that min. 2 and max. 6 layers of web layers are formed. The web layers are aligned in such a way that the outside layers are spun bond layers and the middle layers are melt-blown layers, such that the gsm range is 10-100gms and the web width is up to 1600- 3400mm.
[0050] Web formation from the spun bond beams (min. 2 and max. 3 beams) and the melt flow beams (min. 2 and max. 3 beams), is such that min. 2 and max. 6 layers of web layers are formed. The layers are aligned in such a way that the outside layers are spun bond layers and the middle layers are melt-blown layers, such that the gsm range is 10-100gms. Web width up to 1600-3400mm. Spunbond is a type of fabric or material that is made from polypropylene fibers that are spun into a continuously distributed fabric. Meltblown nonwoven fabric production technology is to extrude, melt and plasticize polymer resin through a screw extruder, and then accurately measure it by a metering pump and deliver it to the melt-blown die head through a melt pipeline. The melt-blown fabrics consist of smaller diameter filaments, including sub-micron filaments, and have superior filtration properties, while conventional spun bond fabrics contain coarser fibres and have much greater tensile strength and smaller pressure drop.
[0051] The web formation process can be done by dry-laid technology-based nonwovens. The dry-laid web-forming process is referred here to as carding: a web-forming process that separates small tufts into individual staple fibers, to begin the process of parallelization, and delivers the fibers in the form of a web.
[0052] The raw materials are natural staple fibres (Cotton, Silk, Wool, Jute, Hemp, Ramie) Or Regenerated man-made fibres like Viscose, Bamboo, Modal, Tencel, Cellulose Acetate, PLA, PVA Or Synthetic Staple fibres (PET, PP, PVA, Nylon) Or Blends in any % of any of the above fibres having staple length 20-120mm and fibre denier of 0.9-4 D.
[0053] The web formation process for wet-laid technology-based nonwovens and the principle of wetlaying is similar to paper manufacturing. The difference lies in the amount of synthetic fibres present in a wet laid nonwoven. A dilute slurry of water and fibres is deposited on a moving wire screen, where the water is drained and the fibres form a web.
[0054] Raw materials Pulp fibres with length up to 5mm and cellulosic staple fibres with length up to 12mm.
[0055] The web formation process for the spun melt technology-based nonwovens where the spunmelt-type of non-woven fabric is processed as follows: extrude and stretch the polymer to form a continuous filament, lay the filament into the web, then process the web into nonwoven fabric through their bonding, thermal bonding, chemical bonding, or mechanical reinforcement methods.
[0056] Polymer granules are extruded of PP, PE, PET, PVA, PLA and Nylon wherein the molten polymer is formed with a melt flow index of 1-100 MFI for spun bond fibers and 1000-1800 MFI for melt blown fibers.
[0057] At step (106), the web laid (randomly) from spun bond and melt-blown beams are calendared at high temperatures (100-150 degrees Celsius) and pressure. The bond density of the calendared melt-blown beams may be around 10-25%, such that the gsm range is 10-100gms. The speed of the web bonding may be done at around 100-400 m/min, which changes as per the gsm. The Web width of the non-woven fabric ranges from 1600-3400 mm.
[0058] Calendaring at high temperatures and pressure improves the bonding between the spunbond and melt-blown layers, creating a strong and cohesive non-woven fabric thereby ensuring that the layers remain intact during use, reducing the chances of delamination or structural failure. The calendaring process helps achieve uniform thickness and consistency across the non-woven fabric, ensuring that the non-woven fabric has consistent absorbency and enhanced performance characteristics including improved absorbency, strength and bonding.
[0059] The controlled bond density of the non-woven fabric ranging from 10-25% allows for an optimum balance between absorbency and permeability. The controlled bond density ensures that the non-woven fabric may effectively absorb fluids while maintaining breathability, enhancing the overall comfort for the user.
[0060] The ability to achieve a GSM range of 10-100 gms provides flexibility in tailoring the weight of the non-woven fabric and thickness according to specific product requirements, catering to different absorbency needs for various types of sanitary napkins.
[0061] The high-speed web bonding process, ranging from 100-400 m/min, ensures efficient production of the non-woven fabric. The speed may be adjusted based on the GSM range, optimizing the manufacturing process and reducing production time.
[0062] The wide web width range of 1600-3400mm allows for the production of various sizes and types of sanitary napkins. This scalability and versatility enable manufacturers to cater to different market demands and product specifications.
[0063] The web bonding for dry-laid technology-based nonwovens can be done using hydro-entanglement needle punch or air-through technology. The web bonding process for wet-laid technology-based nonwovens can be done using the hydro-entanglement technology. The web bonding for the spun melt technology-based nonwovens can be done using thermal bonding / with hot calenders.
[0064] At step (108), the organic botanical tropical treatment is done on the fabric. The bonded fabric is impregnated with an organic solution developed using the botanical extracts of lemon grass. The organic solution has a concentration of lemon grass around 0.5-10%, which changes with the gsm (10-100gms) and speed of the manufacturing process. The Web width of the non-woven fabric ranges from 1600-3400 mm. The concentration range of 0.5-10% achieves the desired benefits without overpowering the fabric with excessive botanical extracts, ensuring that the organic solution effectively imparts its properties, such as odor control and antibacterial effects.
[0065] At step (110), the impregnated nonwoven (with organic botanical extract) is dried at a temperature ranging from 50-80 degrees Celsius, which changes with the gsm (10-100gms) and speed of the manufacturing process. The dried impregnated nonwoven is a non-contact-type drier for contactless drying of the non-woven. The web width of the non-woven fabric ranges from 1600-3400 mm.
[0066] Drying the impregnated nonwoven at the specified temperature range ensures a controlled drying process. The drying of the non-woven is essential to prevent overheating or under-drying, which could adversely affect the properties and performance of the fabric. Impregnating the bonded web with an organic botanical extract, wherein the organic botanical extract solution in the impregnated nonwoven is in a range of 0.5-10% (108); and drying the impregnated bonded web to form the non-woven fabric (110).
[0067] At step (112), the dried nonwoven is wound on 3” or 6” inch cores, and jumbo rolls are packed.
[0068] At step (114), the slitting is done in narrow widths starting from 60mm to 1600mm. It enables efficient storage, customization, production scalability, waste reduction, and improved handling for downstream processing, contributing to the overall effectiveness and cost-efficiency of the manufacturing process.
[0069] A non-woven fabric comprises a plurality of spunbond fibers, derived from thermoplastic polymer granules with a Melt Flow Index (MFI) in a range of 1-100, a plurality of melt-blown fibers originating from the thermoplastic polymer granules having MFI in a range of 1000-1800 and a botanical extract infused into the fabric wherein the botanical extract is in a range with a 0.5-10% concentration.
[0070] The fabric is made up of several spunbond fibers, derived from thermoplastic polymer granules with a Melt Flow Index (MFI) ranging from 1 to 100. Additionally, the fabric contains melt-blown fibers also originating from thermoplastic polymer granules, but with an MFI in the range of 1000 to 1800. The fabric has a botanical extract infused into it, with a concentration ranging from 0.5% to 10%.
[0071] The thermoplastic polymer used in the fabric may include one or more compatible polymers, their copolymers, or blends and composites. Polypropylene is one example of such a polymer.
[0072] The fabric undergoes calendaring procedures at temperatures between 50 to 150 degrees Celsius, resulting in a bond density ranging from 10% to 30%. Calendaring is a process that enhances the strength of the fabric and durability by applying heat and pressure.
[0073] Further, the fabric comprises a botanical extract derived from lemongrass. Providing the antibacterial and anti-inflammatory properties. The dimensions of the fabric may vary in web width from 1600mm to 3400mm. This versatility in width makes the fabric adaptable for various uses, allowing it to be customized to fit different applications. The GSM range of 10-100gsm of the non-woven fabric may be manufactured with varying thicknesses, making it suitable for a wide range of applications where different levels of fabric thickness are required.
[0074] Further, the fabric may be effectively employed in a variety of applications, including but not limited to dry wipes, sanitary napkins, medical textiles, tablecloths, curtains, and hygiene products. Furthermore, the fabric is engineered to impart its unique properties, such as antibacterial, antimicrobial, odor control, anti-inflammatory, and antioxidant attributes, to these applications. This versatility makes the fabric a valuable innovation in multiple industries, improving product performance and potentially enhancing user experience.
