Color fastness, also known as dye fastness or color fastness.

Color fastness, also known as dye fastness or color fastness, refers to the resistance of textile colors to various influences during processing and use. The fastness grade is evaluated based on the color change of the sample and the color transfer to the undyed backing fabric.

Textiles are subject to various external influences during use, such as light exposure, washing, ironing, perspiration, friction, and chemicals. Some printed and dyed textiles also undergo special finishing processes, like resin finishing, flame retardant treatment, sand washing, and abrasion finishing, which necessitates that the colorfastness of printed and dyed textiles be maintained at a certain level.

Color fastness refers to a product's resistance to washing and abrasion.

So-called color fastness, abbreviated as color fastness, refers to the degree of color fading a dyed fabric experiences when subjected to external factors (compression, friction, washing, rain, sun exposure, light, saltwater immersion, saliva immersion, water stains, sweat stains, etc.) during use or processing. It is an important indicator for fabrics. Common types include wash, light, friction, and sweat resistance, as well as ironing and climate resistance.

In practice, testing items are primarily determined based on the product's use and standards. For instance, the standard for woolen textile products specifies the need to test the color fastness to sunlight, while knitted underwear naturally requires testing for perspiration resistance. Outdoor textiles, such as awnings, light box fabrics, and canopy materials, of course, must be tested for their resistance to weathering.

Including: soap wash color fastness (swatch), abrasion color fastness, dry cleaning color fastness, actual wash color fastness (garments, fabrics), perspiration color fastness, water color fastness, light fastness, seawater color fastness, saliva color fastness, etc.
