  • Patent number: 11952690
    Abstract: A breathable and waterproof non-woven fabric is manufactured by a manufacturing method including the following steps. Performing a kneading process on 87 to 91 parts by weight of a polyester, 5 to 7 parts by weight of a water repellent, and 3 to 6 parts by weight of a flow promoter to form a mixture, in which the polyester has a melt index between 350 g/10 min and 1310 g/10 min at a temperature of 270° C., and the mixture has a melt index between 530 g/10 min and 1540 g/10 min at a temperature of 270° C. Performing a melt-blowing process on the mixture, such that the flow promoter is volatilized and a melt-blown fiber is formed, in which the melt-blown fiber has a fiber body and the water repellent disposed on the fiber body with a particle size (D90) between 350 nm and 450 nm.

  • Publication number: 20240100511
    Abstract: A manufacture method of a deodorization fiber includes: a mixing step including mixing zirconium phosphate and a first dispersant including an amine-group compound in a solvent to form a mixture; a grinding step including grinding the mixture until a D90 particle size of zirconium phosphate is 0.1 ?m to 1.5 ?m to form a grinded mixture; a heating and stirring step including heating and stirring the grinded mixture to uniformly distribute zirconium phosphate and the first dispersant in the solvent to form a deodorant; a blending and pelletizing step including blending and pelletizing the deodorant and polyester to form a fiber masterbatch; and a melt spinning step including melt spinning the fiber masterbatch to form the deodorization fiber. A deodorization fiber is further provided.

  • Patent number: 11746285
    Abstract: An intrinsic fluorescent green fiber includes 98.00 to 99.00 parts by weight of a carrier, 0.10 to 0.20 parts by weight of a yellow colorant, 0.08 to 0.20 parts by weight of a blue colorant, and 1.00 to 1.50 parts by weight of a titanium dioxide. When a content of 0.10 wt % to 0.20 wt % of the yellow colorant and a balance of the carrier are mixed to form a yellow fiber, the L*, a*, and b* values of the yellow fiber are respectively between 101.27 and 101.72, between ?17.61 and ?13.47, and between 89.84 and 108.79. When a content of 0.08 wt % to 0.20 wt % of the blue colorant and a balance of the carrier are mixed to form a blue fiber, the L*, a*, and b* values of the blue fiber are respectively between 55.60 and 66.80, between ?22.69 and ?22.70, and between ?37.50 and ?31.80.
