What are the characteristics of anti-static clothing fabrics?
Anti-static clothing is made of polyester filament and high-performance conductive fiber through a special process, which has a relatively long-lasting anti-static and dust-proof performance. It can effectively remove the static electricity generated by the human body. Anti-static clothing is widely used in aerospace, biopharmaceuticals, optoelectronic displays, scientific research laboratories, food and cosmetics and other industries.
Anti-static ultra-clean fabrics must have the following three characteristics at the same time: anti-static, no dust, high dust filtration rate
1. Static electricity will attract dust and make the adsorbed dust not easy to be blown away in the wind shower. Therefore, the primary feature of anti-static ultra-clean fabrics is to have anti-static properties. At the same time, this anti-static property must be durable, efficient, and not significantly degraded by daily washing and friction.
2. The fabric must have good dust filtering properties: the dust in the clean room mainly comes from the air flowing in the room and the human body moving indoors. When the equipment conditions are determined, to improve the cleanliness is to control the tiny dust generated by the human body in the clothes to the greatest extent, so as to prevent it from passing through the fabric and entering the air. This is called the high dust filtration rate of the fabric. Improving the dust filtration rate comes at the expense of the breathability of the fabric, so knitted fabrics and loosely woven woven fabrics are not suitable for cleanrooms.
3. The fabric itself does not generate dust: because it is worn in a clean room, it is required that the fabric cannot become a source of dust in the clean room, which determines that the ultra-clean fabric can only be produced with chemically synthesized long fibers. Natural staple fibers such as cotton, hemp, and silk cannot be used in ultra-clean fabrics, although these raw materials can make the fabrics more wearable. At the same time, the selected chemical fiber filaments are required to strictly control the amount of dust generation. Generally speaking, fully matte polyester filament is not suitable for weaving anti-static ultra-clean fabrics. Because the matting agent added in polyester production - titanium dioxide will become a source of pollution.
