Analysis of physical and thermal properties of chiengora fibers

ABSTRACT

This paper excogitates the potential of an unconventional animal fiber in textile applications. The chiengora fiber taken from dog hair has been chosen for this current study to analyze their chemical, physical, morphological, and thermal properties to explore their usage in textiles. Hairs from five different breeds of dogs namely Labrador, Golden retriever, German shepherd, Pomeranian, and Lhasa apso have been characterized and tested in this study. The research revealed that the chemical, morphological, and thermal properties of the hairs of five breeds are similar to each other. However, marked difference is observed in the physical properties of the fiber such as denier and diameter. It is also found that chiengora fibers have more tenacity than other animal fibers and are very coarser than wool fibers. The X-ray diffraction results reveal that chiengora fibers are having higher crystallinity compared to other animal fibers. Only hairs of Lhasa apso and Pomeranian breed have spinnability characteristics using spinning machines due to their finer denier and higher slenderness ratio and may be spun into yarn to create textile products.

摘要

本文介绍了一种非常规动物纤维在纺织应用中的潜力。从狗毛中提取的Chiengora纤维被选择用于当前的研究，以分析它们的化学、物理、形态和热性质，以探讨它们在纺织品中的用途。从五个不同品种的狗，即拉布拉多犬，金毛猎犬，德国牧羊犬，波美拉尼亚和拉萨APSO进行了表征和测试在本研究中。研究表明，五个品种毛的化学性质、形态和热性质基本相似。然而，在纤维的物理特性中观察到明显的差异，如旦旦和直径。还发现，Chiengora纤维比其他动物纤维具有更大的韧性，并且比羊毛纤维粗得多。XRD结果表明，与其它动物纤维相比，Chiengora纤维具有更高的结晶度。只有拉萨APSO和波美拉尼品种的毛发具有纺纱机的可纺性，这是因为细旦细旦和细长比较高，并且可以纺成纱线来制造纺织产品。
