摘要
The chemical footprint (ChF) can identify the harmful effects of discharged chemical pollutants, helping producers to select environmentally friendly chemicals to reduce their negative environmental impact. This paper quantified and evaluated the ChF of the wet processing of cotton fabric with data collected from a dyeing enterprise. The results showed that the discharged sodium hydroxide caused the most severe impact in terms of both human toxicity and ecotoxicity due to the extensive usage and its high toxicity. The discharged sodium carbonate and dimethyl silicone oil also had a greater environmental impact. Comprehensive evaluation of human toxicity and ecotoxicity with a multi-objective grey target decision-making model indicated that the pretreatment process had the most significant impact, followed by the finishing process and dyeing process. More attention should be paid to the pretreatment process, such as the selection of environmentally friendly textile chemicals, in order to reduce the native impacts of the wet processing of cotton fabric.
