全球每一年生產超過800億件服飾，是全球總人口的11倍，帶來的汙染僅次於石化產業，造成浪費也傷害環境。綜觀國內拋棄的衣物中有78%收至舊衣回收桶，僅有3%進行二手買賣或交換，論及二手衣的處理，多數人會將整理乾淨的舊衣丟入綠色回收箱，回收廠則將舊衣重新分類送給社福單位或運往開發中國家變賣。早期中國是舊衣最大接收站，隨著中國經濟起飛、消費水平提升，已從舊衣需求方變成供給端，台灣廠商的優勢逐漸被中國、日本、歐洲等地區所取代，回收廠一間一間倒閉，垃圾量也增加了好幾噸，如何更有效的解決面臨的問題，讓地球能更永續長久，是現階段所需迫切解決的。本研究透過文獻探討與分析，以可再利用的二手衣材質進行系統化分類，進而根據素材屬性設計開發生活應用之特色布藝商品，使舊衣展現不同的風貌並增加重複使用率，為循環經濟產業注入活水，也盡一份心力為臺灣環境努力成就更綠意的未來。

The world produces more than 80 billion pieces of clothing every year, which is eleven times the total population of the world. The pollution caused is second only to the petrochemical industry, causing waste and harming the environment. Overviewing the domestic discarded clothing, 78% is received in the old clothes recycling bin, and only 3% is used in second-hand trading or exchange. When it comes to the treatment of secondhand clothes, most people will throw the cleaned old clothes into the green recycling bin. The old clothes will be reclassified and sent to social welfare units or shipped to developing countries for sale by recycling factory. In the past, China was the largest receiving station for used clothes. As the Chinese economy took off and the consumption level improved, it has changed from the demand side of used clothes to the supply side. The advantages of Taiwanese manufacturers have gradually been replaced by China, Japan, Europe and other regions. The amount of garbage has increased by several tons. How to solve the problems faced more effectively and make the planet more sustainable is the urgent solution needed at this stage. In this study, through literature discussion and integrated analysis mode, the reusable second-hand clothing materials are systematically classified, and then the design and development of life appropriate fabric products based on the material attributes, so that the old clothes show different styles and increase the reuse rate. Injecting living water into the circular economy industry, it also makes every effort to achieve a greener future for Taiwan's environment.
