探讨棉织品生态附加值的估算方法.以一件纯棉外套的生态设计方案为例,采用碳足迹工具分析、对比了棉织品生态设计前后的环境影响,进而提出了生态附加值的估算方法.结果表明:生态附加值越大,棉织品生态设计所节约的碳排放量就越多.认为:生态附加值的估算可为消费者选择生态棉织品提供明确的生态效益信息,并为生态棉织品的价格优化提供参考依据.%Estimation method of cotton textiles ecological value-added was discussed. Taking the eco-design case of one pure cotton coat as example, environmental impact of before and after cotton textile eco-design was analyzed and contrasted by carbon footprint tool,then estimation method of cotton textiles ecological value-added was put forward. The result shows that the larger the ecological value-added is,the more carbon emissions can be saved in cotton textile eco-designis. It is considered that clear ecological benefits information can be provided to consumer by cotton textiles ecological value-added, then reference basis can be provided for price optimization of ecological cotton textiles.
