What should be the characteristics of clean room fabrics in clean rooms?
Since the clean clothes are worn in the clean room, it is necessary that the cloth cannot be used as a dust source in the clean room. This means that the ultra-clean cloth can only be produced by chemically synthesized long fibers. Natural short fibers such as cotton, hemp, silk, etc. cannot be applied to ultra-clean fabrics, although these materials can make the fabrics more pleasing. Therefore, the clean clothes use polyester filaments to reduce the amount of dusty polyester filaments.
Clean clothing fabrics must have excellent dust filtering. The dust in the clean room comes mainly from indoor air and indoors. When the condition of the equipment is judged, the forward cleanliness is also required to control the fine dust of the human body in the clothes with great limits, and let it pass through the cloth and enter the air. This is the so-called cloth filter with a high dust rate. The forward dust filter rate is at the expense of the breathability of the fabric, so knitted fabrics and woven fabrics that are relatively loosely woven are not suitable for use in clean rooms.
