Refers to the color of textiles color fastness to the processing and use of resistance in the process. The specimen color and not staining to evaluate the fastness of the dye lining fabric grade. Test for colour fastness of textiles is a routine internal quality testing of textiles project.
In use or in the process of dyeing fabrics, subjected to external factors (squeezing, rubbing, washing, rain, sunlight and so on) under the degree of fading, is an important indicator of fabric. Fabrics in the processing and use of process conditions vary greatly, requirements vary,
Most of the existing test method is according to the role of environment and conditions for simulation or test, methods of test for colour fastness is quite extensive. But the international standards organization (ISO), the United States dye and chemical Association (AATCC), Japan (JIS),
United Kingdom (BS), and many other standards, is still the most commonly used washable, light resistance, resistance to friction and sweat resistance, iron, resistant to weather.

Colour fastness to rubbing, light fastness, color fastness to washing resistance, colour fastness to seawater resistance, color fastness to dry cleaning, heat-resistant fastness, dyes in storage Migration feature, etching and color fastness to alkali-spot ...
