What is a Clean room waste cloth?

A waste cloth for a clean room is a waste cloth developed for use in a clean environment including a clean room. A clean environment is an environment in which the number of particles per unit volume (dust, dust, etc.) is set and the cleanliness is controlled. Ordinary waste cloths such as those made of rayon have the property of easily generating dust and dirt (toughness), and cannot be used in such a highly clean environment. A special fiber material and manufacturing method are used for the clean room waste cloth, and the toughness is suppressed compared to the normal waste cloth. Many of them have resistance to chemicals and solvents, high liquid absorption, and few impurities, and are suitable for use under harsh conditions such as manufacturing processes.

Application of Clean room waste cloth

The most important feature of clean room waste is its low toughness. Therefore, it is used in fields where contamination and scratches caused by a small amount of dust and dirt are greatly affected. Specific application fields include the electronics industry field including semiconductors and disks, and the medical field. For example, in the case of a disc, if foreign matter such as fiber waste is mixed in during manufacturing, it may cause a recording error of the disc. By using a clean room wipe for wiping work in the manufacturing process, it is possible to prevent such problems from occurring.
