What characteristics of dust-free clothing can meet the needs of the microelectronics industry
Some production links in the microelectronics industry have very strict requirements on electrostatic voltage and cleanliness, and production operations need to be carried out in cleanrooms. Cleanroom clothing not only protects personnel but also protects processes and products. Therefore, the materials used must meet: comfortable to wear and at the same time Acts as a sufficient barrier between the wearer and the environment, washable and durable; contains anti-static fibers to reduce static hazards. the
Dust-free clothing must have the following characteristics at the same time:
A. It has anti-static function to prevent clothes from being dust-absorbed and difficult to clean. At the same time, this anti-static performance must be durable and efficient, and will not decay due to daily washing and friction.
B. Because it is worn in a clean room, it is required that the fabric cannot become a source of dust in the clean room, so it can only be produced with chemically synthesized long fibers. Polyester filament is currently the most common and widely used dust-free clothing Selection of fabrics.
C. To improve the cleanliness is to control the tiny dust produced by the human body in the clothes to the greatest extent, and prevent it from being distributed into the air. This requires that the dust-free clothing fabrics have good dust filtering properties. However, improving the dust filtration rate is at the expense of fabrics and air permeability, so loosely woven fabrics are not suitable for clean rooms.
