Its technical requirements are divided into three parts, the appearance of the fabric, the point-to-point resistance of the fabric and the physical and chemical indicators of the anti-static work clothes fabric. Today, Qingdao Meian Apparel Editor and everyone Let's learn about the physical and chemical indexes of anti-static work clothes fabrics.
The physical and chemical indicators of anti-static work clothes fabrics include eight aspects, namely the formaldehyde content (mg/kg), PH value, dimensional change rate (%), air permeability (mm/s), and water fastness/grade of anti-static work clothes fabrics. (Discoloration, staining), dry rubbing fastness/grade (discoloration, staining), light fastness/grade (discoloration, staining) and breaking strength (N).
Different physical and chemical indicators have different test methods and correspond to different national standards. It can be seen that qualified anti-static work clothes have quite strict requirements. Only when they meet the corresponding requirements can they be qualified anti-static work clothes.
