Textile material is an electrical insulator material, the specific resistance is generally very high, especially the low moisture absorption performance of polyester, acrylic, chloroprene and other synthetic fibers. Therefore, in the textile process, due to the close contact and friction between fiber and fiber or fiber and machine parts. Cause the transfer of charge on the surface of the object, resulting in static electricity.
The fibers with the same charge repel each other, and the fibers with different charges are attracted to the machine parts, resulting in hairiness of sliver, increase of yarn hairiness, poor package forming, fiber sticking and wrapping machine parts, increase of yarn breakage, and formation of scattered strip shadow on the cloth surface. After the clothing is charged, a large amount of dust is adsorbed, which is easy to stain, and the clothing and the human body, clothing and clothing will also be entangled or spark. Therefore, electrostatic interference affects the smooth progress of processing, affects the quality of the product and the wearing performance of the fabric. When the electrostatic phenomenon is serious, the electrostatic voltage is as high as several thousand volts, which will generate sparks due to discharge, causing fire and causing serious consequences.
The use of stainless steel fiber, sub-conductive fiber, antistatic synthetic fiber and polyester cotton blended or mixed woven fabric, can automatically corona discharge or leakage discharge, can eliminate the clothes and the human body charged, at the same time for antistatic hats, socks, shoes. Its performance indicators meet the GB12014-89 standards:
Cloth charge density ≤ 5 μC/m2
Jacket with charge ≤ 0.5 μC/m2
anti static clothing ten standard:
1. Anti-static work clothes: In order to prevent the accumulation of static electricity on clothes, work clothes sewn with anti-static fabrics for fabrics.
2, antistatic fabric: to prevent the accumulation of static electricity in clothing, in the textile, roughly spaced or evenly mixed with conductive fiber fabric.
3. Conductive fiber: fiber made by composite spinning method using metal oxide or carbon black.
4, clothing appearance requirements: no damage, spots, dirt and other defects affecting the performance of clothing.
5. Antistatic fabric performance: under the environment of temperature 20±5 ℃ and humidity 30 ~ 40%, after washing for 100 times, the average surface charge density of the fabric is ≤ 7.0 μc/m2.
6. Anti-static clothing performance: the charged charge of each anti-static clothing is less than 0.6 μc/piece, and the washing resistance (Grade A ≥ 33.0 h, Grade B ≥ 16.5 h).
7, anti-static clothing inspection standards: People's Republic of China anti-static clothing national standard (GB12014-89).
8, anti-static clothing inspection basis: GB/T12703-1991 "textile electrostatic test method".
9. Anti-static fabric dyeing requirements: light mercerization, no sanding. Please try to control the oxygen bleach at 80% of the dose.
10. Requirements for wearing antistatic clothing: It is forbidden to wear and take off in flammable and explosive places; It is forbidden to wear any metal objects on antistatic clothing. Wear with antistatic shoes.
