This standard is designed to guide the green design evaluation of various types of color spinning yarns produced from cotton and chemical fibers as the main raw materials. It includes terms and definitions, evaluation requirements, preparation requirements for self-evaluation reports and product lifecycle evaluation reports, and the basis for green design product judgment. Applicable reference documents include a series of national standards, covering energy consumption calculation, water pollutant discharge, water-saving enterprise evaluation, energy measurement equipment management, Spinning & weaving product safety technical specifications, etc. Among them, "green design" refers to the activities that comprehensively consider the impact of each link on the resource environment in the product design and development stage according to the life cycle concept, in order to minimize resource consumption, reduce pollutant emissions, and achieve environmental protection. And "color spinning" refers to the colored yarn spun by thoroughly mixing different Color fibers.
