Material orFabricFiber, is an electrical insulating material, the specific resistance is generally very high. Especially low moisture absorption of polyester, polyacrylonitrile fiber, chlorinated fiber and other synthetic fibers. The main reason for the generation of static electricity in fabric materials is that in the fabric finishing process, due to the close contact and friction between fibers and fibers, fibers and machine parts, the transfer of charge on the surface of the object, resulting in static electricity. Fibers with the same charge repel each other, and fibers with different charges and machine parts attract each other. As a result, sliver hair, yarn hairiness increase, poor package forming, fiber sticking and wrapping machine parts, yarn breakage increase, and scattered stripes formed on the cloth surface. Clothing with static electricity, will be a large number of adsorption of dust, easy to stain;
After the working clothes are charged, a large amount of dust will be adsorbed and contaminated, and the working clothes and human body, working clothes and working clothes will also be entangled or spark will be generated. Therefore, electrostatic interference affects the smooth progress of finishing and the quality of products.FabricTaking performance, etc. When the electrostatic phenomenon is severe, the electrostatic voltage is as high as several thousand parties, which will generate sparks due to discharge, causing fire and causing severe consequences. Anti-static fabric is a fabric anti-static fabric treated by anti-static finishing. After washing for 100 times under the environment of temperature 20±5 ℃ and humidity 30 ~ 40%, the average surface charge density of the fabric is ≤ 7.0 μc/m2. To the electrostatic fabric color requirements are light silk finish, not sanding. Please complete the dose of oxygen bleach at 80% of the dose. There are usually the following finishing methods for antistatic fabrics: fabrics are post-finished with antistatic finishing agents; Second, fiber graft modification, hydrophilic fiber blended chemical fiber fabric and interleaving for the purpose of improving the moisture absorption of fabrics; Third, blended chemical fiber fabric or embedded conductive fiber; The mechanism of the first two methods is to improve the moisture regain of the fabric, reduce insulation and accelerate electrostatic leakage. Therefore, if the finishing effect is not durable or significant in a dry environment or after repeated cleaning, it is usually applied on general workwear fabrics. Only the third method can solve the electrostatic problem of fabric products in a lasting and efficient manner, so it is widely used in the production of electrostatic working clothes. The fabric is post-finished with an antistatic post-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.
