The basic requirements of anti-static clothing and the requirements of fabric characteristics are to minimize the dust pollution of the human body, which requires that it cannot become a source of dust itself, and at the same time, it is necessary to take into account the prevention of spontaneous dust generation of the human body and the generation of anti-static. In order to achieve such a protective effect, there are special requirements for the fabrics used to manufacture clean clothes. Dust-free anti-static fabric is also called anti-static ultra-clean fabric, which is different from ordinary anti-static fabric.

It must have the following characteristics at the same time:

A. It has anti-static function to prevent clothes from being vacuumed and difficult to clean. At the same time, this anti-static performance must be durable and efficient, and will not be attenuated by daily washing and friction.

B. The fabric itself does not generate dust. Because it is worn in a clean room, it is required that the fabric cannot be the source of dust in the clean room. This determines that it can only be produced with chemically synthesized long fibers, while cotton, linen, silk, etc. Natural fibers cannot be used in ultra-clean fabrics.

C. It must have good dust filtering performance. The dust particles in the clean room mainly come from the indoor flowing air and the moving human body. When the equipment conditions are determined, to improve the cleanliness is to control the tiny dust generated by the human body in the clothes to the greatest extent, and prevent it from being released into the air. This is called the highest dust filter rate. However, improving the dust filtration rate comes at the expense of fabric and breathability, so loosely woven fabrics are not suitable for clean rooms.
