In daily use and consumer feedback, it has been found that the most common issues with textile color fastness are as follows:

1. Unqualified color fastness to friction

During daily use, textiles may experience varying degrees of color fading due to different degrees of friction. For example, the sleeves of clothes, the hips, and knees of pants are all parts of our clothing that are prone to color fading. Therefore, we usually use a friction tester Crockmeter to test the fabric's resistance to friction.

2. Color fastness to perspiration is unqualified

In the hot summer, clothes, especially underwear, often fade due to the sweat stains from our body when worn. Therefore, we usually use Perspiration Tester sweat stain tester to test the friction resistance of fabrics.

3. The color fastness to washing with water, color fastness to washing with soap and color fastness to dry cleaning are unqualified

During the washing process, whether it is water washing, soap washing, or dry cleaning, dyed fabrics are prone to color changes after washing, and fabrics with poor color fastness are suitable for dry cleaning. Therefore, we usually use Water Colour Fastness Tester for fabric friction resistance testing.

4. The color fastness to sunlight is not up to standard

During the wearing process of our clothing, the color of the fabric will change depending on the degree of sunlight exposure. Areas that are exposed to more sunlight will become lighter or darker in color, while areas that are not exposed to sunlight will have less color change. Therefore, we usually use Light Fastness Tester for fabric friction resistance testing.
