This standard is a fundamental and general method in the field of textile color fastness testing, primarily evaluating the extent to which various textiles shed color or stain other objects under daily friction. The standard clearly includes two testing procedures: dry rubbing and wet rubbing, which assess color durability by simulating friction conditions encountered in actual use. The test requires the use of a professional rubbing fastness tester, which drives a specific rubbing head to perform reciprocating friction on the sample under specified pressure. After completing the friction, the staining level on the rubbing cloth is assessed by comparing it with the standard gray scale, thereby determining the color fastness grade of the textile. This method is applicable to yarns, fabrics, and textile products made from various types of fibers.
