Cleaning and Process
Clean clothing is special work clothing with dust-free and anti-static properties suitable for industries such as electronics, optical instruments, pharmaceuticals, microbial engineering, precision instruments, etc. The clothing material is generally synthetic fiber fabric with conductive yarn embedded in it. .
The most important part of the management of clean clothes is cleaning. Although the fiber itself is a clean fiber that is difficult to get dirty, how to maintain it is an important factor, that is, the cleaning method. Of course, if you use ordinary washing methods, it will get stained. So special methods must be used. In terms of clean compliance management, cleaning and packaging must also be done in a clean room during cleaning.
Under normal circumstances, clean work clothes are washed at least once a week, and some demanding types of work are even washed once a day.
Newly sewn clean work clothes can be washed directly, but if oil stains are found in recycled clean work clothes, the oil stains should be carefully removed before washing.
Before washing, check for scratches, damage, buckles and other accessories, and repair, replace or scrap any defective items.
Washing, drying, and packaging must be done in a clean room that is cleaner than the clean room where work clothes are used.
The water used for wet and dry cleaning must be filtered, and the solvent must be distilled before using a filter membrane smaller than the pore size at the point of use. Filter it more than once as needed.
In order to remove water-soluble contaminants, after washing with clean water, use distilled solvent for final washing to remove oily contaminants.
The water temperature for wet washing is as follows
Polyester cloth

During the final rinse and water penetration, an antistatic agent can be used to improve the antistatic properties, but the antistatic agent selected should be well combined with the fiber and no dust will fall off.
Work clothes with buckles should be washed in the buckled state.
Dry in a clean air circulation system dedicated to washing.
After drying, fold it up in a clean room dedicated to washing and put it into a clean polyester bag or nylon bag. It can be double-packed or vacuum-sealed according to requirements. It is best to use packaging materials with good antistatic properties. s material. Since the folding process is most likely to generate dust, the folding process must be carried out in a higher-level purified space. For example, the folding and packaging of class 1 clean work clothes should be carried out in a class 1 environment.
