What is the fabric of the anti-static clothing?
The human body is a serious source of pollution. The surface of human skin emits particles, and the divergence intensity varies and varies with different people over time. The average surface area of a person is 1.75 square meters. The skin metabolism of the outer skin is updated every time. Once in a few days. Therefore, people emit hundreds of thousands of particles every minute, millions of particles with a diameter of 0.5 microns and above, and the total amount of particles emitted every day and night reaches 10 grams.
Most of the pollution comes from human skin and non-clean room clothing, but the surface of clean clothing fabrics will also spread pollution. The production of clean fabrics should not increase the pollution burden.
People emit inert and microbe-carrying particles when they sneeze, cough and talk. When people touch the surface, they spread the contamination from their hands to the surface of the clean room. Depending on the level of the clean room, it may be necessary to wear masks, clean shawl caps and dust-free gloves to minimize the spread of such pollution.
The best-designed cleansing clothes cover the whole body of the person, and have a good seal at the wrists, necks and ankles. Although it is selected according to the level of the clean room, the clean room standard with higher cleanliness requires the use of one-piece full-body suits, sleeve boots and hooded one-piece clean suits. The higher the technical requirements of the clean room, the greater the degree of restriction or discomfort for people. Therefore, we should consider what is needed according to the cleanliness standard of the room. As long as the cleanliness and process requirements allow, work clothes with a lower coverage rate can be accepted. Some enhanced devices are equipped with a built-in clean air system, and the required clean clothes can be simplified.
There are two categories of clean room clothing: disposable (or restricted use) and reusable. In general, disposable or restricted-use garments are made of non-woven materials and used only once or several times, and then discarded. Reusable clothing is treated regularly. Clean clothing is usually made of ultra-fine polyester filament + conductive fiber. This kind of fabric has the characteristics of: the fabric itself does not generate dust, does not absorb dust, has no dust removal, and has good barrier properties. High density, high strength, high temperature resistance and other properties. Optional fabrics: 5mm strip, 5mm grid, 2.5mm grid fabric conductive silk, its dust-proof and anti-static effect is getting stronger and stronger.
