Comparative Evaluation of Stocking Products Based on Product Life Cycle Assessment

Abstract

Objective In order to analyze the difference of environmental benefit between different processes of silk stockings products, the article puts forward the method of product life cycle analysis to provide reference for the subsequent selection and optimization of production process of silk stockings products. Methods The representative target products in silk stockings were selected, and the full life cycle model of production, use and waste of target products was established by product life cycle method. The two technologies were compared and evaluated quantitatively by analyzing relevant environmental impact indexes, and the reasons for the difference were analyzed by refining the product production process. Conclusion Dope dyed stocking fabric is more environmentally friendly than traditional dyed stocking fabric. The production process of a product is the link that has the greatest impact on the environment in the entire life cycle and the main link that causes the environmental differences between the two processes. The product life cycle model established in this paper can be used as a reference for the life cycle analysis of other similar fabric products, and it proposes a normalized index suitable for evaluating environmental benefits in other industries.
