摘要
以细旦丙纶长丝的生产过程作为分析对象,利用生命周期分析(LCA)方法,选取6项环境影响类别包括全球变暖潜值(GWP)、酸化效应潜值(AP)、陆地生态毒性潜值(TETP)、光化学氧化潜值(POCP)、富营养化潜值(EP)、能耗(EC),量化丙纶细旦长丝生产过程的环境影响;将细旦丙纶长丝织造成布、再制成运动装,与涤纶布和锦纶6布及运动装进行LCA对比分析,并对比分析运动装生产过程的碳排放量。结果表明:相同质量下,3种布在6项环境影响指标中各有优势;相同面积下,细旦丙纶布的6项环境影响类别数值均最小,对环境的影响最小;在6项环境影响类别中,细旦丙纶运动装的各项数值均为最小,其中生产1件运动装的GWP仅为1.92%kg CO_(2) eq.;在3种运动装的生产过程中,细旦丙纶运动装生产阶段中碳排放量最高的为织造阶段,占比31%,涤纶运动装和锦纶6运动装生产阶段中碳排放量最高的均是纤维制备阶段,占比分别为35%和41%。
Taking the production process of fine denier polypropylene filament as the analysis object,six environmental impact categories,namely global warming potential(GWP),acidification effect potential(AP),terrestrial ecotoxicity potential(TETP),photochemical oxidation potential(POCP),eutrophication potential(EP),energy consumption(EC),were selected by using the life cycle analysis(LCA)method to quantify the environmental impact of the production process of fine denier polypropylene filament.The fine denier polypropylene filament and its fabric and sportswear were analyzed and compared with polyester and nylon 6 and their fabrics and sportswears by LCA,as was the carbon emission in the production process of sportswear.The results showed that the three kinds of fabrics had their respective advantages in six environmental impact indicators under the same weight mass;the fine denier polypropylene fabric possessed the lowest values in all the six environmental impact categories and gave the minimal impact on the environment under the same area;the sportswear made of fine denier polypropylene fabric also possessed the lowest values in all the six environmental impact categories,and GWP was only 1.92 kg CO_(2) eq.for one piece of sportswear;and in the production process of three kinds of sportswear,the weaving stage had the highest carbon emission in the production stage of fine denier polypropylene sportswear,accounting for 31%,while the fiber preparation stage had the highest carbon emission in the production stage of polyester and nylon 6 sportswears,accounting for 35%and 41%respectively.
