Introduction to the characteristics of anti-static fabrics

Textile materials, especially those with low hygroscopicity, such as polyester, acrylic, and Kevlar, have high specific resistance. Therefore, during the textile processing, due to the close contact and friction between the fibers and the fibers or the fibers and the resulting static electricity, the hairiness of the slivers, the increase of the yarn hairiness, the defective package formation, the fiber-adhering components, and the yarn breakage Increased heads and the formation of dispersive shadows on the cloth.

After the clothes are charged, a large amount of dust is adsorbed on the clothes and it is easy to stain. Moreover, clothing and the human body, clothing and clothing can also be accompanied by phenomena or sparks. Therefore, electrostatic interference affects the smooth progress of processing, and affects the quality of the product and the performance of the fabric. When the electrostatic phenomenon is serious, the static voltage is as high as several kilovolts. Sparks may be generated by the discharge, causing fire and serious consequences. Anti-static fabrics are made of anti-static fabrics. Anti-static fabrics have an average surface area of ​​≤ 7.0 μc/m2 after being washed 100 times in a temperature of 20±5°C and a humidity of 30 to 40%. Anti-static fabric dyeing requirements are light mercerized, not brushed. Oxygen bleach should try to control 80% of the dose.

Anti-static fabrics are generally processed in several ways: first, fabrics are treated with an antistatic finish; second, fiber graft modification, hydrophilic fiber blending, and interweaving for the purpose of improving the fabric's moisture absorption Third, blended or inlaid conductive fibers; the first two methods of action mechanism are to increase the fabric moisture regain, reduce insulation, and accelerate electrostatic discharge. Therefore, if the processing effect is not durable or insignificant in a dry environment or after multiple washings, it is usually applied to ordinary clothing fabrics. Only the third method can solve the electrostatic problem of textiles in a lasting and efficient manner, so it is widely used in the production of anti-static work clothes. The fabric is finished with an antistatic finish. The types of anti-static fabrics include: anti-static silk (conductive silk) and anti-static ultra-clean fabrics, anti-static tc fabrics, anti-static tr fabrics, anti-static cvc fabrics, anti-static cotton fabrics.

It is worth mentioning that organic conductive fibers play an effective role in static elimination of anti-static overalls fabrics and ordinary civilian textiles, but compared with conventional textiles, electrostatic properties testing of textiles containing conductive fibers is correct and important. The method deteriorated significantly. Choosing a reasonable test method and correctly evaluating the electrostatic properties of fabrics containing conductive fibers is a fundamental work necessary to thoroughly study the processing technology of organic conductive fibers, the production process of textiles containing conductive fibers, and the rational application of such textiles. We analyze the adaptability of China's current relevant test method standards for the testing of antistatic performance of fabrics containing conductive fibers.

The clothing made of anti-static fabrics mostly uses stainless steel fibers, sub-conductive fibers, anti-static synthetic fibers and polyester/cotton blended or mixed weaving fabrics. It can automatically corona discharge or leak discharge, eliminating clothes and human body, and also providing anti-static electricity. Hats, socks, shoes. Among them, anti-static overalls can prevent electrostatic accumulation of clothes, and work clothes made of anti-static fabrics for sewing fabrics. Antistatic fabrics, on the other hand, can prevent static electricity from accumulating in the fabric. In the case of textiles, fabrics of electrically conductive fibers are roughly spaced or evenly mixed.
