Analysis of the characteristics of antistatic fabrics

Fabric material or fabric fiber is an electrical insulating material, and its resistivity is generally high. Especially polyester with low hygroscopicity, polyacrylonitrile fiber, polyvinyl chloride and other synthetic fibers. The main reason for the generation of static electricity in fabric materials is that during the finishing process of fabric, due to the close contact and friction between fibers and fibers, fibers and machine parts, the transfer of charges to the surface of the object causes static electricity. . Fibers with the same charge repel each other, and fibers with different charges and machine parts attract; The result is fluffy sliver, increased yarn hairiness, poor bag formation, fiber sticking to machine parts and increased yarn breakage, as well as the formation of scattered stripes on the surface of the fabric, etc. Once the garment is charged with static electricity, it will absorb a large amount of amount of dust and easy to get dirty.
After charging the work clothes, a large amount of dust is absorbed, which is easy to become dirty, and the work clothes and the human body, work clothes and work clothes will also become entangled or generate electric sparks. Thus, electrostatic interference affects the smooth running of finishing, affects the quality of products and the wear resistance of fabrics, etc. will lead to fire and serious consequences. Antistatic fabrics are fabrics that have undergone antistatic finishing treatment. After {{0}} repeated washing of antistatic fabrics at a temperature of 20±5 degrees C and humidity 30-40%, the average surface charge density of the fabric is Less than or equal to 7.0 µC/m2. The color requirement for antistatic fabrics is a light, silky finish without sanding. Please control the amount of oxygen bleach at 80% of the dose.
There are usually several finishing methods for antistatic fabrics: the fabric is treated with an antistatic finishing agent; second, modification of fiber grafting to improve the hygroscopicity of fabric, chemical blend fabric of hydrophilic fibers and weave; third, mixed chemical fiber fabrics or embedded conductive fibers; The mechanism of action of the first two methods is to increase the moisture transfer of the fabric, reduce thermal insulation and accelerate the leakage of static electricity. Therefore, unless the finishing effect is durable or obvious in a dry environment or after repeated washing, it is usually applied to general workwear fabrics. Only the third method can permanently and effectively solve the problem of static electricity in fabrics, so it is widely used in the production of antistatic work clothes. The fabric is treated with antistatic agent. 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 noting that organic conductive fibers have played an effective role in removing static electricity from antistatic workwear fabrics and general civilian fabrics. The approach to sex and attention has deteriorated significantly. Selecting a reasonable test method and properly evaluating the electrostatic properties of fabrics containing conductive fibers is the main work required for in-depth research on the finishing technology of organic conductive fibers, the production process of fabrics containing conductive fibers, and guiding rational methods. Application of such fabrics. We are analyzing the applicability of the relevant test method standards in my country to testing the antistatic performance of fabrics containing conductive fibers.
Work clothes made of antistatic fabrics mainly use stainless steel fibers, semiconductive fibers, antistatic synthetic fibers and chemical fiber fabrics of polyester and cotton blend or mixed fabrics, which can automatically create corona discharge or leakage discharge, which can remove clothes and charges the human body, and at the same time provides antistatic protection for hats, socks, and shoes. Among them, anti-static work clothes can prevent the accumulation of static electricity in clothing and work clothes made of anti-static fabrics as fabrics. Anti-static fabric can prevent static electricity from accumulating on clothing. When fabrics, fabrics with conductive fibers are located approximately at a distance from each other or evenly mixed.
