Antibacterial regenerated polyester fiber lining cloth and production process thereof

Abstract

The invention relates to antibacterial regenerated polyester fiber lining cloth and a production process thereof. The lining cloth is weaving lining cloth, and warp yarns and weft yarns of the liningcloth contains antibacterial modified regenerated polyester fiber low stretch yarns. The production process comprises the following steps: preparing regenerated polyester fibers by virtue of a physical regeneration method or a chemical regeneration method, modifying the surfaces of the regenerated polyester fibers to generate functional groups capable of adsorbing silver ions on the surfaces of the regenerated polyester fibers, wherein the functional groups service as the nucleation growth foundation of reduced nano-silver particles, are continuously accumulated with a reducing agent to generate silver atoms, and the nano-silver particles are grown; and carrying out high-temperature preheating on silver-loaded regenerated polyester fibers so as to softening the surfaces of the regeneratedpolyester fibers, embedding the nano-silver particles into the surfaces of the regenerated polyester fibers under a negative pressure, and carrying out rapid cooling and formation, so as to embed thenano-silver particles into the surfaces of the regenerated polyester fibers. According to the production process, the problems that the antibacterial effect of the lining cloth is poor, the productioncost is high, and the antibacterial property is difficult to be guaranteed in the prior art are solved; and the antibacterial modified regenerated polyester fiber low stretch yarns have the antibacterial performance, and the antibacterial property is not degraded after the antibacterial modified regenerated polyester fiber low stretch yarns are washed for several times.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an antibacterial regenerated 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 ef...

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 increasing the antibacterial substance in the dye of the spun base cloth, thereby further increasing the antibacterial property of the present utility model; the production cost of this invention is high, and the durability of the best antibacterial performance is limited

[0012] Chinese patent CN207535426U discloses a kind of antibacterial breathable adhesive interlining cloth, comprises base cloth, and the top and bottom of base cloth are brushed with coating, and 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
