GB/T 29597-2013

This standard specifies a test method for determining the stability of reactive dyes when exposed to alkaline conditions, simulating the dyeing process where alkali is used to fix the dye onto cellulose fibers. It is applied in the textile and chemical industries for quality control of reactive dyes, ensuring they maintain their chemical structure and performance during alkaline dyeing baths. Manufacturers and testing laboratories use this standard to evaluate dye suitability for cotton, linen, and other cellulosic fabric processing.
