Characteristic analysis of anti-static fabrics
Fabric material, or fabric fiber, is an electrical insulating material, and its specific resistance is generally very high. Especially polyester, polyacrylonitrile fiber, chlorine fiber and other synthetic fibers with low hygroscopicity. The main cause of static electricity in fabric materials is that during the fabric finishing process, due to the close contact and friction between fibers and fibers, fibers and machine parts, the charge is transferred on the surface of the object, resulting in static electricity. Fibers with the same charge repel each other, and fibers with different charges attract each other. As a result, the hairiness of the sliver will increase, the hairiness of the spinning yarn will increase, the package formation will be poor, the fiber will stick to the machine parts, and the yarn will break. , and the formation of dispersed stripes on the cloth surface. When clothing is charged with static electricity, it will absorb a large amount of dust and is prone to contamination;
When work clothes are charged, they will absorb a large amount of dust and become easily contaminated. In addition, the work clothes and the human body, work clothes and work clothes will also become entangled or generate electricity. spark. Therefore, static interference affects the smooth progress of finishing, affects the quality of products and the wearing performance of fabrics. When the static electricity phenomenon is serious, the static voltage can reach several thousand volts, which can cause sparks due to discharge and cause fires, causing serious consequences. Anti-static fabric is a fabric that has been treated with anti-static finishing. After being washed 100 times in an environment with a temperature of 20±5°C and a humidity of 30-40%, the average surface charge density of the anti-static fabric is ≤7.0 μc/m2. The coloring requirement for anti-static fabrics is light silk finish and no sanding. Please control the oxygen bleach at 80% of the dosage. There are usually several finishing methods for anti-static fabrics: first, the fabric is finished with an antistatic finishing agent; second, fiber graft-modified and hydrophilic fiber blended chemical fiber fabrics are used for the purpose of improving the fabric’s hygroscopicity. and interleaving; third, blended chemical fiber fabrics or inlaid conductive fibers; the first two types of methods have the mechanism of increasing fabric moisture regain, reducing insulation, and accelerating electrostatic leakage. Therefore, if the finishing effect is not durable or not significant in a dry environment or after multiple cleanings, it is usually used on general workwear fabrics. Only the third method can permanently and efficiently solve the static problem of fabrics, so it is widely used in the production of anti-static workwear. The fabric is finished with an antistatic finishing agent. The types of anti-static fabrics include: anti-static silk (conductive silk) and anti-static ultra-clean fabrics, TC anti-static fabrics, CVC anti-static fabrics, anti-static Cotton fabrics, etc. It is worth mentioning that organic conductive fibers play an effective role in removing static electricity from static workwear fabrics and general civilian fabrics. However, compared with conventional fabrics, the electrostatic performance test of fabrics containing conductive fibers has to be accurately tested. Sexual and sexual approach significantly worsened. Choosing reasonable testing methods and correctly evaluating the electrostatic properties of conductive fiber-containing fabrics are basic work necessary to conduct in-depth research on the finishing technology of organic conductive fibers, the production process of conductive fiber-containing fabrics, and to guide the rational application of such fabrics. We analyze the adaptability of my country’s current relevant test method standards to the antistatic performance testing of fabrics containing conductive fibers. Work clothes made of anti-static fabrics mostly use stainless steel fibers, sub-conductive fibers, anti-static synthetic fibers and polyester-cotton blended chemical fiber fabrics or blended fabrics. They can automatically discharge corona discharge or leakage discharge, and can remove electricity from clothing and the human body while providing electricity. Anti-static hats, socks, and shoes. Among them, anti-static work clothes can prevent the accumulation of static electricity in clothing. Work clothes sewn from anti-static fabrics. Anti-static fabrics can prevent the accumulation of static electricity in clothing. When fabrics are made, conductive fibers are mixed into the fabric at roughly intervals or evenly.
