Antistatic Performance of Workwear in Workshops
Antistatic workwear is widely used in electronics factories, pharmaceutical factories, and chemical plants. What are the principles and testing methods for the antistatic performance of antistatic workwear in workshops? The antistatic function of antistatic workwear is usually achieved through special finishing processes, such as coatings, surface metallization, and the use of conductive fiber materials (metal fibers, metal-plated fibers, conductive composite fibers, etc.) in pure spinning, blending, or interweaving.
The testing methods for antistatic workwear in workshops are selected based on the fabric. The evaluation of the antistatic performance of antistatic workwear should employ different methods depending on the fabric properties, and the test items will also vary depending on the method. Static electricity testing includes testing of hazardous static electricity parameters, testing of the static electricity properties of materials and products, and testing of the static electricity sensitivity of flammable and explosive materials. The main parameters of the static electricity performance of antistatic workwear in workshops include resistivity, leakage resistance, charge density and half-life, and triboelectric voltage and half-life. The evaluation of the electrostatic performance of antistatic work clothes in workshops mainly includes resistance indicators, electrostatic voltage and half-life, surface charge density, and simple, low-precision test indicators such as dust attraction test, sail tension test, and metal sheet adsorption test.
