Cleanroom wiper, also known as dust-free wiping cloth, is made of 100% polyester fiber double woven. It has a soft surface, can be used to wipe sensitive surfaces, and does not take off fiber after friction. It has good water absorption and cleaning efficiency. Cleanroom wiper is often used in semiconductor assembly, aviation manufacturing and maintenance, computer assembly, laboratory and other places. How can we reuse the cleanroom wiper and reduce the cost?
