長纖紡織業的碳足跡分析

Abstract

本研究計算有競爭力的個案商品如環保聚酯、環保尼龍、環保機械彈、原抽色紗其產品生命週期的碳足跡，並且為產品規劃推廣方法，對世界上較知名之運動、戶外、瑜珈、日常生活衣物的各品牌以及其供應鏈中長纖紡織業一階與二階供應商們行銷 。 以產品生命週期的減碳程度來看，環保尼龍的成衣可減碳26%、環保聚酯的成衣可減碳13%、環保機械彈的成衣可減碳63%、原抽型環保聚酯色紗的成衣可減碳33%、原抽型聚酯色紗的成衣可減碳20%、原抽型環保尼龍色紗的成衣可減碳43%、原抽型尼龍色紗的成衣可減碳17%，不同比例減碳對於品牌有不同的行銷方法。

This study analyzes the carbon footprint of competitive products such as recycled polyester, recycled Nylon 6, recycled mechanical stretch polyester and dope dyed yarns. This research is intended to promote filament textile for famous brands and their suppliers in sports, outdoor activity, yoga, daily wear industries. In the life cyce accessment (LCA), our research findings show that the recycled nylon can reduce carbon footprint by 26%, recycled polyester can reduce carbon footprint by 13%, recycled mechanical stretch polyester can reduce carbon footprint by 63%, recycled dope dyed polyester can reduce carbon footprint by 33%, virgin dope dyed polyester can reduce carbon footprint by 20%, recycled doped dyed Nylon 6 can reduce carbon footprint by 43% and virgin doped dyed nylon can reduce carbon footprint by 17%. There are different selling punches for brands and suppliers with different requirement about carbon footprint.
