About Color Fastness

Frequently asked questions about fabric color fastness:

1.The sun fastness is unqualified. During the wearing process, the parts exposed to sunlight are lighter or discolored (generally the back and shoulder parts), and the colors that are not irradiated or irradiated are not changed or lightly changed, resulting in a product with the same original color. The colors are different and can no longer be used.

2.The color fastness to washing, the color fastness to soaping and the fastness to dry cleaning were unqualified. Advanced silk clothing, wool clothing, and cotton clothing are the most prone to this problem.

3.The color fastness to rubbing is unqualified. During the use of the fabric, the degree of discoloration varies depending on the degree of friction of the different parts of the product. For example, the tops of the shirt, the elbows of the sleeves, the collar and the underarms are the easiest to fade. In addition, the hips and knees of the pants are also easy to fade.

4.The color fastness of perspiration was unqualified. Mainly summer clothes or close-fitting underwear are faded by the impregnation of sweat when worn.
