T/CPCIF 0040-2020 Green Design Product Evaluation Technical Specification for Liquid Dispersive Dyes

Scope

Scope: This document specifies the terms and definitions, evaluation principles, evaluation requirements, evaluation methods, and preparation methods for life cycle assessment reports of green design products of liquid disperse dyes. This document applies to the evaluation of green design products of liquid disperse dyes prepared by dye synthesis. The evaluated products are suitable for dyeing and printing on clothing that adults directly contact with their skin, but not suitable for dyeing and printing on clothing for infants and children under 36 months. Main technical contents: 4.1 Evaluation principles 4.1.1 Principle of combining life cycle assessment with indicator evaluation According to the life cycle assessment method, considering the entire life cycle of liquid disperse dye products, from product design, raw material acquisition, product production, product use, and waste recycling and treatment stages, we deeply analyze the resource consumption, ecological environment, and human health factors at each stage, and select evaluable indicators from different stages to form an evaluation indicator system. 4.1.2 Principle of optimally selecting environmental impact types According to the characteristics of liquid disperse dye products, we select environmental impact types that have a significant impact, high social attention, and clear requirements in national laws or policies, such as resource attributes and pollutant emissions.
