紡織品微纖維脫落的影響因素

近年來，關於使用塑膠製品所產生的塑膠微粒（Microplastic）汙染海洋的環保議題，出現越來越多的研究與討論，且研究發現存在海洋之塑膠微粒大約20～35%是來自合成纖維的紡織品，進而衍生出紡織品於洗滌過程或穿著使用中所脫落的微纖掉毛（Microfiber Shedding）測試評估與解決方案探討，以致於國際間各學術研究機構、戶外聯盟品牌商及布料供應商陸續投入研究及開發。本篇參照〈一種評估微纖掉毛新試驗方法之研究〉，使用實驗室標準化洗衣設備Gyrowash，並在固定水量、固定溫度與時間下，進行微纖脫毛率測試。在試樣無或有預水洗10次處理情況下，試驗結果呈現7個試樣之脫毛率落在0.048～0.1666%，且同試樣有預水洗10次處理的脫毛率均較小。在比較不同組織結構條件下，5個試樣包含：刷毛、磨毛、夾紗的布料，試驗結果呈現夾紗試樣脫毛率最少為0.040%。關於進行織物熱阻抗測試，在試樣無或有預水洗10次處理情況下，試驗結果呈現7個試樣之保暖值（Clothing Insulation，CLO）落於0.17～0.91之間。比較不同組織結構條件下，5個試樣的試驗結果，呈現刷毛試樣保暖值最高為0.76 CLO，且夾紗（Inlay）組織為0.37 CLO，優於一般厚毛衣的0.35。觀察發現，同試樣在有或無預水洗10次情況下，微纖維脫毛率與保暖值呈負向關係。

In recent years, there have been more and more researches and discussions on the environmental protection issues of the marine pollution caused by the use of plastic microplastics, and studies have found that approximately 20-35% of microplastics in the ocean from synthetic textiles. And then derive test evaluation and solution discussion of microfiber shedding from textiles during washing or wearing, and it has successively invested in research and development in various international academic research institutions, outdoor group brands and fabric suppliers. This article refers to the "Study on a new test method of evaluating microfiber shedding", using the laboratory standardized laundry equipment "Gyrowash", and testing the microfiber shedding rate under a fixed amount of water, temperature and time. In the case of specimens without or with pre-washing for 10 times, the test results showed that the shedding rate of 7 specimens fell from 0.048 to 0.1666%, and the shedding rate of all specimen with pre-washing for 10 times was smaller. Under the condition of comparing different textile structure structures, 5 samples include fabrics with bristles, sanding, and inlay. The test results show that the fabrics with inlay of shedding rate is the lowest 0.040%. Regarding the fabric test thermal resistance, the test results showed that the clothing insulation (CLO) of 7 specimens was between 0.17 and 0.91 when the specimens were treated without or with pre-washing for 10 times. In the case of specimens without or with pre-washing for 10 times, the thermal resistance test results showed that the clothing insulation (CLO) of 7 specimens was between 0.17 and 0.91. Under the condition of comparing different textile structure structures, the test results of the 5 samples showed that the clothing insulation value of the bristle specimen was the highest 0.76 CLO, and the inlay specimen was 0.37 CLO, which was better than the general thick sweater 0.35. It was observed that in the same specimen with or without pre-washing for 10 times, the microfiber shedding rate was negatively related to the clothing insulation value.
