A kind of antibacterial polyester fiber lining cloth and its production process

Abstract

The invention relates to an antibacterial polyester fiber interlining and a production process thereof. The interlining is a woven interlining, including warp yarns and weft yarns, and the warp yarns and weft yarns include antibacterial modified polyester fiber low-elastic yarns; The surface is modified to produce functional groups such as hydroxyl and carboxyl groups on the surface, which can absorb a large amount of silver ions and serve as the basis for the nucleation and growth of reduced silver nanoparticles. After encountering the reducing agent, this growth continues to accumulate into silver atoms, and finally grow into nano-silver particles, and then preheat the silver-loaded polyester fiber at high temperature to soften the surface of the polyester fiber, and embed it on the surface of the fiber under a certain negative pressure. After rapid cooling and molding, the nano-silver particles grow embedded in the polyester fiber Fiber surface; the present invention solves the problems of poor antibacterial effect, high production cost, and difficulty in guaranteeing antibacterial durability of the interlining in the prior art. not weakened.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an antibacterial polyester fiber interlining and a production process thereof. Background technique [0002] The interlining is based on woven fabrics, knitted fabrics and non-woven fabrics, and is made of thermoplastic polymer compounds. After special finishing and processing by special machinery, it is used for reinforcing and stiffening the inner layer of clothing, and is bonded to the fabric. special clothing accessories. Interlining is the skeleton of clothing, and good interlining is the essence of clothing, especially the application of modern interlining, which makes clothing modeling and sewing technology get unexpected effects. The function of interlining can be roughly summarized as the following aspects: [0003] 1. Give the clothing a good curve and shape; [0004] 2. Enhance the stiffness and elasticity of clothing and enhance the three-dimensional effect; [00...

AI Technical Summary

Problems solved by technology

Existing antibacterial method mainly comprises: 1, directly adopt natural or regenerated antibacterial fiber (bamboo fiber, hemp fiber, chitin fiber), high cost; 2, add antibacterial agent in spinning solution during chemical fiber spinning, in order to guarantee Spinnability and spinning uniformity, the addition amount is limited, and the antibacterial effect is not good; 3. After conventional antibacterial finishing of the fabric, it is difficult to ensure long-lasting antibacterial, and the durability is poor

[0011] Chinese patent CN204930484U discloses an antibacterial and breathable adhesive interlining. By replacing the polyester fiber and cotton fiber of the traditional interlining with a mixed fiber of polyester fiber, cotton fiber and chitin fiber, the traditional interlining has antibacterial properties. And by adding antibacterial substances in the dye of the woven base fabric, thereby further increasing the antibacterial properties of the interlining; the invention has high production costs, and the durability of the best antibacterial properties is limited

[0012] Chinese patent CN207535426U discloses an antibacterial and breathable adhesive interlining, including a base cloth, the top and bottom of the base cloth are coated with a coating, and the coating is added with TiO 2 , when it is irradiated by the sun or ultraviolet rays, it will form active oxygen with oxygen or moisture in the air, and active OH will be produced on the surface - , O 2 It has a strong oxidation effect, which makes the bacteria decompose and sterilizes. The base fabric is composed of an upper base fabric and a lower base fabric. There are elastic fibers between the upper base fabric and the lower base fabric. The elastic fibers are coated with antibacterial agents. Antibacterial ability, the invention can achieve better antibacterial effect in the early stage, but the antibacterial persistence is limited

[0013] Chinese patent CN204682609U discloses a kind of bamboo fiber bonding antibacterial interlining, which adopts low-melting point polyester fiber and natural bamboo fiber blended yarn, and the mass ratio of low-melting point polyester fiber to natural bamboo fiber is 3%-70%. The number is 6-80, the production cost of this invention is high, and the antibacterial effect is limited, and the antibacterial effect is restricted by the cost
