AI Technical Summary

Benefits of technology

This patented technology describes an anti-bacterial fabric that contains certain types of polymers called hydroxypropyltrimethylammonium chloride (HPMA). These compounds help absorb water vapors from human body while also promoting their release over time through various mechanisms such as diffusion or chemical reactions between them. By combining these different materials into one material, this new type of fabric becomes better at killing germs without causing any harmful side effects like adding extra ingredients for added functionality.

Problems solved by technology

This patented technology describes how certain types of polymers (such as thermoplastics) absorb humidity while keeping them wet but cannot effectively release moistened liquid during wear. To solve this problem, an antiwax coating called Teflon® may be added onto some surfaces of the material's yarns. These coatings help prevent condensation caused by excessive heat buckling between adjacent threads. By doing this, they improve resistance against wearing and provide lubricant benefits like reducing friction. Additionally, the inventors found that specific combinations of different chemical substances were able to create various fibrous structures containing both moieties and antimicrobons. Overall, these technical means aim to enhance performance and comfort level of clothing products.

Embodiment 1

[0016] After polyester A, hydrophilic modified polyester masterbatch B and antibacterial polyester masterbatch C raw materials are sliced ​​and dried, they are fed into the screw for blending and melting at a mass percentage of 60:20:20, in which silver, copper, and zinc ionophores are antibacterial The weight of the agent accounts for 6% of the total weight of the fiber. After being metered by a metering pump, it is input into the spinning box (295° C. of spinning temperature), extruded by a special-shaped spinneret with a three-lobed plate hole, blown and cooled, and drawn ( Drawing temperature 90 ℃, drafting ratio 3.0 times), setting (temperature 120 ℃), winding (speed 5000m / min), made hydrophilic trilobal polyester FDY filament with antibacterial function.

Embodiment 2

[0018] After the raw materials of polyester A, hydrophilic modified polyester masterbatch B and antibacterial polyester masterbatch C are sliced ​​and dried, they are input into the screw for blending and melting according to the mass percentage of 93:5:2, and the silver, copper, and zinc ionophores are antibacterial The weight of the agent accounts for 1% of the total weight of the fiber. After being metered by a metering pump, it is input into the spinning box (spinning temperature 295 ° C), extruded from a special-shaped spinneret with cross-shaped plate holes, blown and cooled, and wound (speed 1200m / min). The winding POY yarn is stretched and stretched (drawing temperature 170°C, drafting ratio 1.6 times), and the hydrophilic cross-shaped polyester DTY filament with antibacterial function is obtained.

Embodiment 3

[0020] After the raw materials of polyester A, hydrophilic modified polyester masterbatch B and antibacterial polyester masterbatch C are sliced ​​and dried, they are input into the screw for blending and melting at a mass percentage of 80:15:5, and the silver, copper, and zinc ionophores are antibacterial The weight of the agent accounts for 2% of the total weight of the fiber. After being metered by the metering pump, it is input into the spinning box (spinning temperature 280 ° C), extruded from the special-shaped spinneret with the I-shaped plate hole, blown and cooled, and wound (speed 1000m / min), falling into the drum, the yarn bundled in the falling drum, and then through two stages of drafting: the first stage of drafting (drawing temperature 80°C, drafting multiple 3.5 times), the second stage of drafting (drawing temperature 110°C, drafting elongation 1.1 times), the fiber is crimped, and subjected to a relaxation heat setting treatment at 120°C for 60 minutes, then s...

Abstract

The invention relates to an antibacterial, hydroscopic and perspiratory polyester fiber with self-hydrophilicity, which comprises filaments and chopped fibers. A preparation process comprises the following steps of: blending, fusing and spinning polyesters (including copolyesters), hydrophilic modified polyester master batches (hydrophilic modified polyester is obtained by grafting a hydrophilic group) and antibacterial polyester master batches (including but not limited to carrier antibacterial polyesters of silver, copper and zinc ions) according to a certain proportion; extruding with a special-shaped spinneret plate; and performing an after-treatment process to obtain an antibacterial, hydroscopic and perspiratory polyester filament or chopped fiber. A textile made from the fiber has an excellent antibacterial effect and hydroscopic and perspiratory functions, and can be widely applied to sporting goods brands, socks, underwear and the like.
