Color fastness refers to the resistance of a textile's color to various effects during processing and use. Evaluate the fastness level based on the discoloration of the sample and the staining of the unstained lining fabric. The color fastness test of textiles is a routine testing item in the internal quality testing of textiles. Color fastness: Color fastness refers to the washing and friction resistance of a product. Good or poor color fastness directly affects human health and safety. Products with poor color fastness can cause pigment detachment and fading on the fabric when they come into contact with rainwater and sweat during wearing. The molecules and heavy metal ions of the dye may be absorbed by the skin and pose a threat to human skin health. On the other hand, it can also affect the staining of other clothing worn on the body, Or stain other clothes while washing them. The so-called color fastness (referred to as color fastness) refers to the degree of fading of dyed fabrics under external factors (such as compression, friction, water washing, rain, exposure, light, seawater immersion, saliva immersion, water stains, sweat stains, etc.) during use or processing. It is an important indicator of the fabric. Due to the significant differences in the conditions and requirements encountered during the processing and use of fabrics, most of the current testing methods are simulated or comprehensive tests based on the working environment and conditions. Therefore, the content of dyeing fastness testing methods is quite extensive. But looking at many standards such as the International Organization for Standardization (ISO), the American Association of Colorists and Chemists (AATCC), Japan (JIS), and the United Kingdom (BS), the most commonly used ones are still washing resistance, light resistance, friction resistance, sweat resistance, ironing resistance, and weather resistance. In practical work, the testing items are mainly determined based on the final use of the product and the product standard. For example, the standard for wool textile products stipulates that color fastness to sunlight must be tested, knitted underwear must be tested for color fastness to sweat stains, and outdoor textiles (such as sunshades, lightbox fabrics, and fluffy materials) must be tested for color fastness to climate.
