What is the function of cleanroom garments?
Cleanroom garments are primarily used in workshops and cleanrooms with high cleanliness standards; consequently, the garments themselves must meet rigorous requirements regarding cleanliness. They offer excellent performance and effectiveness, specifically in the following areas:
A. Antistatic capability: This prevents the garments from attracting dust-which would make cleaning difficult-and ensures the antistatic properties remain durable and highly effective, without degrading due to daily washing or friction.
B. Non-dust-generating fabric: Since these garments are worn in cleanrooms, the fabric itself must not become a source of particulate contamination. This necessitates the use of long-staple synthetic fibers; natural fibers such as cotton, linen, and silk are unsuitable for ultra-clean fabrics.
C. Effective dust filtration: Dust particles in a cleanroom originate mainly from circulating air and the movement of personnel. Once equipment parameters are fixed, improving cleanliness levels requires containing the microscopic dust generated by the human body within the garment, preventing its release into the air-essentially maximizing the dust filtration rate. However, increasing filtration efficiency often comes at the cost of fabric breathability; therefore, loosely woven fabrics are not suitable for cleanroom use.
Cleanroom garments are subject to extremely high standards, not only regarding their own properties but also regarding their cleaning process. The cleaning standard must align with the specific cleanliness requirements of the work environment; otherwise, the garments are considered non-compliant.
