Colour fastness is an important assessment of textile quality and is also the most complained about quality issue by consumers. There are many methods of testing the colour fastness of textiles, in addition to conventional items such as washing resistance, rubbing, water, perspiration and light, there are also special items such as nitrogen oxide resistance, ozone resistance, fume resistance, phenol yellowing resistance, weather resistance and UV/carbon arc light ageing resistance according to different simulated use scenarios. Good or poor colour fastness is directly related to the beauty and durability of the product, and even affects human health and safety. Our colour fastness testing service has many years of technical experience and professional, comprehensive and accurate testing capabilities, helping you to accurately consider the colour fastness level of textiles, avoid quality risks and improve product quality.
