Textile materials, especially synthetic fibers with low hygroscopicity, such as polyester, acrylic and chloroprene, have high specific resistance. Therefore, in the process of textile processing, due to the close contact and friction between fiber and fiber or between fiber and machine parts, static electricity is generated, resulting in sliver hairiness, increased yarn hairiness, poor package forming, fiber binding machine parts, increased yarn breakage, and scattered streaks on the cloth surface
when the clothing is charged, it will absorb a large amount of dust, which is easy to contaminate. Moreover, the clothing and human body, clothing and clothing will also be entangled or produce electric sparks. Therefore, electrostatic interference affects the smooth processing, product quality and fabric wearability. When the electrostatic phenomenon is serious, the static voltage is as high as several thousand volts, which will produce sparks due to discharge, causing fire and serious consequences. Anti static fabric is the fabric after anti-static processing, anti-static fabric in the temperature of 20 ℃ ± Under the condition of 5 ℃ and 30-40% humidity, after 100 times of washing, the average surface charge density of fabric is less than or equal to 7.0 μ c/m2. Anti static fabric dyeing requirements are light mercerization, no sanding. Oxygen bleaching agent should be controlled at 80% of the dosage
there are several processing methods of antistatic fabric: first, the fabric is finished with antistatic finishing agent; Second, to improve the hygroscopicity of the fabric, fiber grafting modification, hydrophilic fiber blending and interweaving; Third, blended or woven conductive fibers; The mechanism of the former two methods is to improve fabric moisture regain, reduce insulation and accelerate electrostatic leakage. Therefore, if the processing effect is not durable or significant in a dry environment or after repeated washing, it is usually applied to ordinary clothing fabrics. Only the third method can solve the problem of static electricity of textiles persistently and efficiently, so it is widely used in the production of anti-static overalls. The fabric is finished with antistatic finishing agent. The types of anti-static fabrics include: anti-static silk (conductive silk), anti-static super clean fabric, anti-static TC fabric, anti-static tr fabric, anti-static CVC fabric, anti-static cotton fabric, etc
it is worth mentioning that the organic conductive fiber has played an effective role in the electrostatic elimination of anti-static workwear fabrics and ordinary civil textiles. However, compared with conventional textiles, the correctness and importance of the electrostatic performance test of textiles containing conductive fiber have deteriorated significantly. Choosing reasonable testing methods and correctly evaluating the electrostatic properties of fabrics containing conductive fibers are the necessary basic work for further studying the processing technology of organic conductive fibers, the production technology of textiles containing conductive fibers and guiding the rational application of such textiles. We analyze the adaptability of the current test methods and standards in China to the test of antistatic properties of textiles containing conductive fibers
the clothes made of antistatic fabric are mostly made of stainless steel fiber, sub conductive fiber, antistatic synthetic fiber and polyester / cotton blended or blended fabric, which can automatically discharge corona or leakage discharge, eliminate the electrification of clothes and human body, and provide antistatic hats, socks and shoes. Among them, the anti-static work clothes can prevent the accumulation of static electricity in clothes, and the work clothes sewn with anti-static fabric as the fabric. The anti-static fabric can prevent the accumulation of static electricity in clothing. When weaving, the fabric of conductive fiber is mixed in roughly spaced or evenly
