Do you know the main fabrics of anti-static clothing
Anti-static clothing refers to work clothes sewn with anti-static fabric as the fabric to prevent the accumulation of static electricity on the clothing. It has high-efficiency anti-static, dust-proof performance, thin and smooth, and clear texture. Anti-static clothing fabrics on the market now include anti-static ultra-clean fabrics and ordinary anti-static fabrics, and anti-static ultra-clean fabrics are usually called "conductive silk", but only conductive silk suitable for clean rooms can be called It is an anti-static ultra-clean fabric.
What is the difference between anti-static ultra-clean fabric and ordinary anti-static fabric? The main difference lies in the word "super clean". Since our country has not formulated corresponding anti-static ultra-clean fabrics and anti-static fabric testing standards, the selection of anti-static ultra-clean fabrics can only be made by the application units based on experience according to the requirements of the operating environment. When we choose anti-static ultra-clean fabrics, we must first understand some basic knowledge about fabrics. When purchasing, we can use a surface resistance tester to measure the resistance values of the warp and weft conductive threads of the fabrics and compare them. If The resistance in the two directions is the same, which means that this kind of fabric may use anti-static agent, and the performance cannot be maintained for a long time. Then the measured resistance can not be used as a reference; if the resistance in the two directions is different, our comparison principle is: choose The resistance is relatively small; at the same time, the ultra-clean fabric of anti-static clothing must have the following three functions:
1. With anti-static function
The anti-static performance must be durable and efficient, and will not be significantly attenuated due to daily washing and friction.
2. The fabric itself does not generate dust
Because it is worn in a dust-free clean room, it is required that the fabric cannot be the source of dust in the dust-free clean room, which determines that the ultra-clean fabric can only
Use chemically synthesized long fibers to produce, and at the same time strictly control the amount of dust generated by the selected chemical fiber filaments. Although these raw materials such as cotton, linen and silk
Natural can make the fabric more wearable, but these short fiber raw materials cannot be used in ultra-clean fabrics.
3. The fabric should have good dust filterability
The dust in the clean room mainly comes from the air flowing in the room and the human body moving in the room. Improving the cleanliness is also required to maximize
Keep the tiny dust generated by the human body inside the clothes, and don't let it pass through the fabric into the air.
