Pre-consumer waste comes from any excess material produced during the production of yarn, fabrics and textile products, e.g. selvage from weaving and fabric from factory cutting rooms. Post-consumer waste comes from discarded textile products, e.g. used apparel and home textiles. During the recycling process, the cotton waste is first sorted by type and color and then processed through stripping machines that first breaks the yarns and fabric into smaller pieces before pulling them apart into fiber. The mix is carded several times in order to clean and mix the fibers before they are spun into new yarns.〔http://textileexchange.org/node/958〕 The resulting staple fiber is of shorter length compared to the original fiber length, meaning it is more difficult to spin. Recycled cotton is therefore often blended with virgin cotton fibers to improve yarn strengths.〔http://textileexchange.org/node/958〕 Commonly, not more than 30% recycled cotton content is used in the finished yarn or fabric. Because waste cotton is often already dyed, re-dyeing may not be necessary.〔http://textileexchange.org/node/958〕 Cotton is an extremely resource-intense crop in terms of water, pesticides and insecticides.〔http://wwf.panda.org/about_our_earth/about_freshwater/freshwater_problems/thirsty_crops/cotton/〕 This means that using recycled cotton can lead to significant savings of natural resources and reduce pollution from agriculture.〔http://www.bir.org/industry/textiles/〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cotton recycling」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
