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 a fabric's color to various influences during processing and use. The fastness level is determined by evaluating the color change of the sample and the staining of the uncolored interlining fabric.

Textiles are subjected to various external influences during use, such as light, washing, ironing, perspiration, friction, and chemicals. Some printed and dyed textiles undergo special finishing processes, such as resin finishing, flame retardant treatment, sand washing, and abrading, which require the colorfastness of printed and dyed textiles to maintain a certain degree of durability.

Colorfastness refers to a product's resistance to washing and abrasion.

So-called color fastness, abbreviated as color fastness, refers to the degree to which dyed fabric fades under the influence of external factors during use or processing, such as compression, friction, washing, rain, sun exposure, light, sea water immersion, saliva immersion, water stains, sweat stains, and more. It is an important indicator of the fabric. Common types include wash, light, friction, sweat, ironing, and climate resistance.

In practical operations, the testing items are primarily determined based on the product's purpose and standards. For instance, the standard for wool textile products specifies the need to test for resistance to sunlight fading, while knitwear, of course, requires testing for perspiration resistance. Outdoor textiles (such as awnings, signboard fabrics, and canopy materials) naturally must be tested for their resistance to climatic color fastness.

Including: Washfastness to soap (swatch), Abrasion fastness, Dry cleaning fastness, Actual washing fastness (garments, fabrics), Perspiration fastness, Water fastness, Light fastness, Sea water fastness, Saliva fastness, etc.
