What kinds of esd fabrics are there for esd clothes
Anti-static fabrics are fabrics containing conductive threads.
Conventional optional fabrics: 5mm strip, 5mm grid, 2.5mm grid fabric conductive silk, in order, its anti-dust and anti-static effect is getting stronger and stronger; this is also selected according to the clean room level, generally CLASS10000 Clean rooms below (ten thousand zone) should use 5mm strip conductive silk, CLASS1000 (thousands zone) and 5mm grid should be used; CLASS100 (class 100) clean room should use 2.5mm grid fabric conductive silk.
1. The fabric itself does not emit dust: Because it is worn in a clean room, the fabric is required not to be a source of dust in the clean room, which determines that ultra-clean fabrics can only be produced with chemically synthesized long fibers. Natural short fibers such as cotton, linen, and silk cannot be used in ultra-clean fabrics, although these raw materials can make the fabrics more wearable. At the same time, it is required that the selected chemical fiber filaments must be strictly controlled to generate dust. Generally speaking, full-dull polyester filament is not suitable for weaving anti-static ultra-clean fabrics. Because the matting agent added in the production of polyester-titanium dioxide will become a source of pollution.
2. The fabric should have good dust filtering: 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, and let it pass through the fabric into the air. This is the so-called high dust filter rate of the fabric. Improving the dust filter rate is at the expense of the air permeability of the fabric. Therefore, knitted fabrics and loosely woven woven fabrics are not suitable for clean rooms.
