Comparison of Physico-mechanical Properties of Fibre and Yarn Made of Alpaca, Sheep, and Goat Wool

ABSTRACT

Textile industry is one of the most important branches of the economy of many countries in the world and the importance of wool is still huge. Due to the unique properties of natural animal fibers and their positive effect on the human organism, the authors decided to evaluate and compare the quality of fibers and yarn coming from three animal species, i.e., sheep, goats, and alpacas. The study was included the physico-mechanical analysis of properties of fiber and yarn: such as diameter, breaking force, elongation at break, Young modulus, breaking strain and strain energy. The study on the selected physical and mechanical properties of the fibers showed that goat fibers are the stiffest, but concurrently the most durable, while the yarn made of sheep fibers is the most resistant, the yarn of alpaca fibers is the most elastic, and that of goat fibers is the most rigid.

摘要

纺织工业是世界许多国家经济的重要分支之一，羊毛的重要性仍然巨大. 由于天然动物纤维的独特性质及其对人体的积极作用，决定对绵羊、山羊和羊驼三种动物纤维和纱线的质量进行评价和比较. 对纤维和纱线的直径、断裂强力、断裂伸长率、杨氏模量、断裂应变和应变能等性能进行了物理力学分析. 对所选纤维的物理力学性能的研究表明，山羊绒最硬，但同时最耐用，而山羊绒的纱线最耐磨，羊驼纤维的纱线最有弹性，山羊绒的纱线最硬.
