Color fastness, refers to the color of the textile processing and use of a variety of roles in the process of resistance, that is, product resistance to abrasion and washing performance. Color fastness good and bad, directly related to the health and safety of the human body, poor color fastness of the product in the course of the encounter if the rain water, sweat will cause the fabric off the color fade. Which dye molecules and heavy metal ions are likely to be absorbed through the skin and harm the health of the human body, on the other hand will also affect the wear of other clothing is stained, or with other clothing washing stained with other clothing. As the fabric in the processing and use of the conditions suffered vary widely, so the color fastness requirements are also different, so the majority of the current test methods are based on the role of the environment and conditions of the simulation test or a comprehensive test, so dyeing The test method for fastness is quite extensive. However, compared with other countries of the various detection methods, the most commonly used or washing, light, abrasion and perspiration resistance, resistance to ironing, weather and other items of detection. In practical work, mainly based on the end use of products and product standards to determine the test items, such as wool textile products standards must be required to test the color fastness to sun, knitted underwear, of course, to measure perspiration fastness, and outdoor textiles (Such as umbrellas, light box cloth, Peng cover material) is of course to test its weather fastness.

The corresponding test standards:
