The invention relates to a dacron conductive lining cloth and a production process thereof. The production process includes the following steps that polyester chips, carbon black powder and graphene powder are adopted, and double-component polyester skin core conductive composite filaments are prepared; common polyester fiber low stretch yarn is subjected to surface treatment, and antibacterial conductive polyester fiber low stretch yarn is prepared; the prepared double-component polyester skin core conductive composite filaments and the prepared antibacterial conductive polyester fiber low stretch yarn are subjected to doubling and double-twisting compounding, and composite conductive filaments are prepared; the composite conductive filaments are used for weaving the lining cloth. The defects such as poor conductivity, poor softness, washing intolerance and the complex processing process of conductive fibers in the prior art are overcome, the dacron conductive lining cloth has excellent washing resistance, dyeing performance and conductivity, is resistant to abrasion and bending and soft in hand feeling, still can keep good conductivity after being machine-washed multiple times, is good in strength, soft and not crispy, and meets the comprehensive requirements of the strength, softness and conductivity of high-grade antistatic clothing on antistatic lining cloths.

Description

technical field [0001] The invention relates to the technical field of textile interlining, in particular to a polyester conductive 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; [0...

AI Technical Summary

Problems solved by technology

[0011] The antistatic principle of the existing antistatic interlining is the same as that of the antistatic fabric, which mainly includes the insertion of conductive fibers in the weaving process of the fabric to make the fabric antistatic or the chemical modification of the fiber material or the surface coating treatment of the fabric, etc. Among them, the conductive fiber insertion method is one of the most commonly used methods to make the fabric fabric antistatic. For this reason, the conductive fiber has also experienced the development from metal fiber, carbon fiber, conductive material wrapped fiber to composite conductive fiber. The metal fiber Good electrical conductivity, but it is difficult to blend with ordinary fibers, and embedded in the fabric will reduce the softness and feel of the fabric, and even cause itching; carbon fiber has low resistivity, but lacks toughness, and the bending degree is low; wrapped conductive fiber is not good. It is resistant to friction and repeated washing, and the conductive material is easy to fall off; although the existing composite conductive fiber can maintain good conductivity and durability to a certain extent, and the feel and softness of the conductive thread have been improved, but it is still It is difficult to meet the comprehensive requirements of high-end anti-static clothing for the strength, softness and conductivity of anti-static interlinings, and the process is complicated and the manufacturing cost is expensive. The monomers of some conductive polymers are toxic and suspected to be carcinogens and are restricted.

[0012] Chinese patent application CN101349007A discloses a conductive fiber and a preparation method thereof. In the method, the fiber is first warped, and plasma treatment is performed on the warped rows of fibers to form a physical metal coating on the surface of the fiber. Then electroplating the metal layer, the conductive fiber prepared by the above invention has certain conductive properties, but there are problems in the fiber's adsorption firmness to the metal coating, fiber water resistance, breakage resistance and softness.

[0013] Chinese patent CN202045885Y discloses an antistatic interlining, including a base fabric, both sides of the base fabric are coated with an antistatic composite layer, and the antistatic composite layer contains a resin finishing agent, a catalyst, a softener, an antistatic agent and a water repellent. The antistatic interlining has a certain conductivity, but the conductivity is limited, and the antistatic composite layer is easy to fall off the base cloth, not resistant to washing, and the firmness of the composite layer is limited
