The anti-static ultra-clean fabric used in anti-static clothing is usually called "conductive silk." In fact, this statement is not strict. According to its own technical characteristics, conductive silk can be divided into anti-static (ESD) and clean room (CleanRoom). What kind of fabric should be used for anti-static dust-free clothing?
①It has anti-static function: static electricity will attract dust and make it difficult to be blown away when it is exposed to wind. Therefore, the primary feature of anti-static ultra-clean fabrics is anti-static properties. At the same time, this anti-static performance must be durable and efficient, and will not be significantly attenuated by daily washing and friction.
②The fabric itself does not emit 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, which determines that the ultra-clean fabric can only be produced with chemically synthesized long fibers. Natural short fibers such as cotton, linen, and silk cannot be used in ultra-clean fabrics, although these raw materials can make the fabrics more wearable. At the same time, it is required that the selected chemical fiber filaments must be strictly controlled to generate dust. Generally speaking, full-dull polyester filament is not suitable for weaving anti-static ultra-clean fabrics. Because the matting agent added in the production of polyester-titanium dioxide will become a source of pollution.
③Fabrics must have good dust filterability: the dust in the clean room mainly comes from the air flowing in the room and the human body moving indoors. When the equipment conditions are determined, to improve the cleanliness is to control the tiny dust generated by the human body to the maximum extent in the clothes, and let it pass through the fabric into the air.
Only conductive silk suitable for clean rooms can be called anti-static ultra-clean fabrics. The anti-static fabric can be woven fabric, such as conductive silk, anti-static T/C fabric, or knitted fabric, such as anti-static knitted glove cloth, anti-electric knitted underwear, etc. In addition to meeting the general technical standards of textiles, anti-static fabrics must also have good anti-static properties.
