Reference standard for anti-static clothing
Many friends want to know what the national standard of anti-static clothing is and how the reference standard of anti-static clothing is defined. Let ’s take a look below.
1. Anti-static work clothes: In order to prevent the electrostatic accumulation of clothes, work clothes sewed with anti-static fabric for the fabric.
2. Anti-static fabric: To prevent static electricity from accumulating in the clothes. When weaving, the fabric is mixed with conductive fibers at intervals or evenly.
3. Conductive fiber: Fiber made by composite spinning method using metal oxide or carbon black.
4. Apparel appearance requirements: no damage, spots, dirt and other defects that affect the performance of the garment.
5. Antistatic fabric performance: Under the environment of temperature of 20 ± 5 ℃ and humidity of 30 ～ 40%, after washing 100 times with water, the average value of charge surface density of the fabric is ≤7.0μc / m2.
6. Anti-static clothing performance: the charged charge of each anti-static clothing is less than 0.6μc / piece, and the washing resistance (A grade ≥33.0 h, B grade ≥16.5 h)
7. Anti-static clothing inspection standard: National Standard for Anti-static Clothing of the People's Republic of China (GB12014-2009).
8. Antistatic clothing inspection basis: GB / T12703-1991 "Test methods for static electricity of textiles".
9, anti-static fabric dyeing requirements: light mercerizing, not frayed. Please control the oxygen bleaching agent at 80% of the dose.
10. Anti-static clothing wearing requirements: It is forbidden to put on and take off in flammable and explosive places; it is forbidden to wear any metal objects on anti-static clothing; it is to be worn with anti-static shoes.
