The Static Elimination Effect of Antistatic Clothing
Antistatic clothing fabric is made of special polyester filament and high-performance permanent conductive fibers, with a 5mm spacing between the conductive fibers, featuring stripes, and woven using a special process. It has the following three main static elimination effects:
1. Antistatic Function: Static electricity attracts dust, making it difficult for the attracted dust to be blown away during air showers. Therefore, the primary characteristic of antistatic cleanroom fabric is its antistatic properties. Furthermore, this antistatic property must be durable and highly efficient, not significantly diminished by daily washing and friction.
2. Excellent Dust Filtration: Dust in cleanrooms mainly comes from the airflow and the human body moving within the room. Given fixed equipment conditions, improving cleanliness means maximizing the containment of tiny dust particles generated by the human body within the antistatic clothing, preventing them from penetrating the fabric and entering the air. This is what is meant by a high dust filtration rate for the fabric. Increasing the dust filtration rate comes at the cost of fabric breathability; therefore, knitted fabrics and loosely woven woven fabrics are unsuitable for making antistatic clothing.
3. Antistatic cleanroom fabrics themselves do not generate dust: Since they are worn in cleanrooms, the fabric must not be a source of dust in the cleanroom. This dictates that cleanroom fabrics can only be produced using chemically synthesized long fibers. Natural short fibers such as cotton, linen, and silk cannot be used in cleanroom fabrics, even though these materials can improve the fabric's wearability. At the same time, the amount of dust generated by the selected chemical fiber filaments must be strictly controlled. Generally speaking, fully matte polyester filaments are not suitable for weaving antistatic ultra-clean fabrics because the matting agent added during polyester production-titanium dioxide-can become a source of contamination.
