摘要

纺织研究正被推动寻找可持续材料作为原纤维的替代品。事实上,纤维废物作为副产品的再利用是世界面临的最重要的环境挑战之一。本研究的重点是研究拉羊毛纤维作为一种天然纤维,以减少环境负荷。有大量的残余的拉羊毛纤维,可以回收和增值。因此,对生毛和拔毛纤维进行了表征和比较。扫描电镜(SEM)结果表明,拉伸后的羊毛纤维表面变得粗糙,鳞片受到影响,密度降低。根据x射线衍射(XRD)结果,拉伸后纤维的结晶度略有下降。衰减全反射-傅里叶变换红外(ATR-FTIR)光谱分析显示了化学成分的一些变化。高效液相色谱(HPLC)测试显示囊性酸的数量增加。被拉扯的羊毛纤维表明它可能破坏了纤维中的一些大分子链的交联。因此,在化学脱毛过程中,物理、化学和机械性能都会受到影响。本研究的目的是提高羊毛的潜在价值,因为它是天然纤维中最常用的几种应用。

Effect of the Chemical Unhairing Process on Pulled Wool Characteristics
Abstract Textile research is being driven to find sustainable materials as an alternative to raw fibers. In fact, reusing fibrous waste, as a byproduct, is one of the most important environmental challenges that confront the world. This research focused on studying pulled wool fibers as a natural fiber to reduce environmental loading. There are large amounts of residual pulled wool fibers that can be recycled and valorised. Therefore, raw and pulled wool fibers were characterized and compared. Scanning Electron Micrographs (SEM) results show that on the pulled wool fiber, the surface became rougher and the scales appear affected and less dense. Based on the X-ray diffraction (XRD) results, the crystallinity of the pulled fiber decreased lightly. Attenuated Total Reflectance-Fourier Transform Infra Red (ATR-FTIR) spectroscopy analyzes presented some changes in chemical composition. A High-Performance Liquid Chromatography (HPLC) test showed an increase in the amount of cystic acids. The pulled wool fiber indicates that it might have damaged some crosslinks of macromolecular chains in the fiber. Thus, physical, chemical and mechanical properties are affected during the chemical unhairing process. This research purpose was to increase the potential for better value of pulled wool as it presents the natural fiber most used in several applications.
