Physical and chemical properties include breaking strength, breaking strength variation coefficient, elongation at break, line density deviation rate, line density variation coefficient, evenness of thread uniformity, hundred-meter thread defects, twist variation coefficient, 2mm fuzz index, color fastness to soap washing, color fastness to wet friction, allowable deviation rate of length, and the number of knots. Appearance quality includes six items: surface knots, stains, color deviation, color bleeding, loose threads, and spider webs. Safety performance includes formaldehyde content, pH value, color fastness to dry friction, color fastness to water, color fastness to sweat stains, color fastness to saliva (for infants and young children), and degradable carcinogenic aromatic amine dyes, and odor.
