Color fastness refers to the resistance of textile colors to various effects during processing and use. The fastness grade was evaluated based on the discoloration of the sample and the coloration of the undyed lining fabric. The textile color fastness test is a routine test item in the intrinsic quality test of textiles.
Color fastness refers to the product's wash and rub resistance. Good and fast color fastness is directly related to the health and safety of the human body. Products that have poor color fastness and experience rain or sweat during wear will cause pigments on the fabric to fall off and fade. The dye molecules and heavy metal ions have both The skin may be absorbed by the human body and endanger the health of the human skin. On the other hand, it may affect other clothing worn on the body to be stained, or stain other clothes when washing with other clothes. The so-called color fastness (abbreviated as color fastness) refers to the dyeing fabric subjected to external factors (extrusion, friction, water washing, rain, exposure, light, seawater impregnation, saliva immersion, water stains, perspiration) during use or processing. Etc.) The degree of discoloration under action is an important indicator of fabrics. Because the conditions encountered in the processing and use of fabrics vary greatly, and the requirements vary, the current test methods are mostly simulated or comprehensively tested according to the environment and conditions of action. Therefore, the test method for the color fastness The content is quite extensive. However, many standards such as the International Standards Organization (ISO), the American Dyers and Chemists Association (AATCC), Japan (JIS), and the United Kingdom (BS) have been used. The most commonly used ones are wash, light, friction, and perspiration resistance. Ironing, weather resistance and other items. In actual work, test items are mainly determined based on the end use of the product and product standards. For example, wool textile products must be tested for color fastness to sunlight, knitted underwear must be tested for perspiration fastness, and outdoor use. Textiles (such as parasols, light boxes, and canopies) are, of course, tested for their color fastness to weather.
