Color fastness rating

- Nov 02, 2018-

According to the color fastness test, the discoloration degree of dyed fabrics and the staining degree of lining fabrics, the color fastness properties of textiles are graded. Except for light fastness grade 8 (except AATCC standard light fastness), the others are grade 5. The higher the series, the better the fastness. In the color fastness test, the standard grey sample card used to evaluate the staining degree of the dyed fabrics to the lining fabrics is generally called staining sample card.
