Dust-free clothing is widely used in clean workshops in industries such as electronics, pharmaceuticals, food, bioengineering, optics, aerospace, semiconductors, precision machinery, plastics, spray painting, hospitals, and environmental protection. It has two major characteristics:

1. The ESD fabric used in the dust-free clothing does not emit dust. Since cleanroom clothing is mainly used in cleanrooms, this determines that cleanroom clothing fabrics can only be produced with chemically synthesized long fibers, while natural short fibers such as cotton, linen, and silk cannot be used in ultra-cleanroom clothing fabrics. At the same time, the selected filaments should also strictly control the amount of dust generated. Generally speaking, full-dull polyester filaments are not suitable for weaving anti-static and dust-free clothes, because titanium dioxide, a matting agent added in polyester production, will become a source of pollution. Consider this series of material selection and whether it will cause pollution to ensure that the dust-free clothing itself does not become a source of dust and effectively ensures a clean environment in the dust-free workshop.

2. Dust-free clothing has good dust filtering performance. The dust in the dust-free workshop mainly comes from the air flowing indoors and the staff working in the dust-free room. Under the condition that the relevant equipment for controlling indoor air cleanliness is perfect, improving the cleanliness of the dust-free workshop must maximize the The tiny dust produced by the human body is controlled in the clean suit, preventing it from passing through the clean suit and flowing into the air. This requires the dust-filtration performance of the dust-free clothing to be better, relatively speaking, the air permeability of the dust-free clothing must be sacrificed. For this point, ordinary knitted fabrics and relatively loose woven clothing are not suitable for dust-free workshops. .
