Selected Physical and Mechanical Properties of Alpaca Fibers Differing in Color

ABSTRACT

Demand for alpaca fiber is subject to an increase, which is due to its beneficial properties. The study aimed to determine the differences in physical and mechanical properties, as well as heat insulation properties of alpaca fibers differing in color. The research material consisted of Huacaya alpaca fiber samples of white (W), light fawn (LF), medium fawn (MF), dark fawn (DF), and black (BLK) colors. The following properties were examined: diameter, comfort factor (CF), breaking force, elongation at break, tenacity and heat transfer rate. The finest fibers were found in W and DF fleece, while the coarsest ones in MF. CF was the highest in DF fibers. Breaking force LF varied between 6.4 (DF) and 11.7 cN (BLK), while elongation at break was 43.6 (LF) to 54.7% (BLK). No significant differences were found in case of tenacity. The best insulation properties were found for DF fibers. Correlations were confirmed between diameter and mechanical properties, and they differed slightly depending on colors.

摘要

对羊驼纤维的需求会增加，这是由于其有益的特性. 这项研究旨在确定不同颜色的羊驼纤维在物理和机械性能以及隔热性能方面的差异. 研究材料由白色（W）、浅浅黄色（LF）、中浅黄色（MF）、深浅黄色（DF）和黑色（BLK）的Huacaya羊驼纤维样品组成.测试了以下性能: 直径、舒适系数、断裂力、断裂伸长率、韧性和传热率. W和DF羊毛的纤维最好，MF羊毛的纤维最粗. DF纤维的舒适度最高.断裂力LF在6.4（DF）和11.7cN（BLK）之间变化，而断裂伸长率为43.6%（LF）到54.7%（BLK. 韧性方面没有发现显著差异. DF纤维的绝缘性能最好。直径和机械性能之间的相关性得到了证实，并且它们根据颜色略有不同.
