Color fastness refers to the resistance of a textile's color to various effects during processing and use, that is, the product's wash-fastness and rubbing resistance. The color fastness is good and bad, and it is directly related to the health and safety of the human body. If the product with poor color fastness encounters rain or sweat during wear, it will cause the pigment on the fabric to fall off and fade. Dye molecules and heavy metal ions may be absorbed by the human body through the skin and endanger human health. On the other hand, it may affect other clothing worn on the body to be stained, or stain other clothes when washing with other clothes. Button detection standards are:
