Description

POLYMERIC YARN, COMPOSITION AND METHOD
FIELD OF THE DISCLOSURE
[0001] The present disclosure relates to textile industries, and, more particularly, to a polymeric yarn and composition having antimicrobial and/or antibacterial properties.
BACKGROUND OF THE DISCLOSURE

[0002] Textile industry has conventionally been using both natural and synthetic fibers for manufacture of various products. Each having their own advantages and shortcomings related to strength, comfort, softness, longevity and the like. With ever-increasing demand to provide enhanced quality fibers manufacturers apart from enhancing traditional properties, have started incorporating more functional elements to fibers to provide better comfort, freshness, and hygiene to users. In pursuit of meeting demands of modern hygienic lifestyle, there have been several attempts to add a variety of chemical agents to fabrics providing them with antimicrobial and antibacterial properties. These agents are normally applied on the surface to impart antimicrobial and antibacterial properties to the fabrics during finishing stage.

[0003] However, items made with such fabrics are unable to retain antimicrobial and antibacterial properties for long and as the compounds are washed-off during washings or ultra-violet exposure. A significant reason that these fibers are not able to provide long-term antimicrobial and antibacterial effects lies on the fact that these components are added to the fiber during the fabric finishing stage through the use of various finishing chemicals. Moreover, there is always a concern regarding use of such chemical agents and their potential after-effects on human body.

[0004] Therefore, there exists a need for innovation in relation to this technology to overcome the shortcomings prevalent in the market.

Furthermore, at 430 the herbal masterbatch and the base polymer are mixed together in desired ranges such as described above. Moreover, at 440, the mixture of the herbal masterbatch and the base polymer are melted and extruded at a temperature in a range of 175 C to 300 C; preferably in a range of 200 C to 290 C; more preferably in a range of 220 C to 280 C, to obtain the polymeric yarn having the herbal component in a range of 0.01% to 10%; preferably in the range of 1% to 8%; more preferably, greater than 1% to up to 6%, on weight of the polymeric yarn.

[0031] In one embodiment of the present disclosure, the polymeric yarn 100 may be formed by a single-step continuous process, on a single machine line, including the steps of: extruding, spinning, quenching, spin finish application, drawing, and/or texturing, cooling, intermingling and winding at the predetermined parameters. In such embodiment of the present disclosure, the mixture of the herbal masterbatch and the base polymer are melted and extruded at the gradual temperature having a range of 175 C to 300 C through a plurality of temperature zones, and at a pressure range of 60bars to 130bars. Further, the step of spinning is performed, followed by a gradual quenching, at the predetermined parameters, via, Date Recue/Date Received 2021-01-14 an air flow, having a quenching air flow temperature in a range of 10 C to 25 C, quenching air flow rate in a range of 0.1 mt/sec to 0.4 mt/sec, and quenching air flow pressure in a range of lbars to 4bars. After quenching, spin finish application is performed.
