GB/T 25800-2010 "Principles for Naming Textile Dyeing and Finishing Auxiliaries" is a fundamental standard in the textile industry. It establishes unified naming rules for textile dyeing and finishing auxiliaries and applies to the naming specifications of various related auxiliaries. The standard adopts a three-segment naming structure: "prefix modifier + basic name + code." The prefix reflects characteristics such as the application object and process, the basic name is determined according to relevant classification standards, and the code is set by the manufacturer (and may be omitted). Additionally, it retains traditional common names in the industry, reserves naming space for new types of auxiliaries, addresses the issue of chaotic market naming, and imposes no requirements for related testing instruments. This standard provides a unified basis for product identification and circulation in the industry.
