摘要
气候的寒冷和对轻质服装的需求,使得越来越多的研究集中于绝热织物.目前除了传统的羊毛和山羊绒外,其他一些珍稀动物毛发引起研究者们的兴趣,因为毛发是这些耐寒动物赖以生存的重要因素.采用光学显微镜与扫描电子显微镜研究了海狮、白唇鹿、牦牛和北极熊等4种耐寒动物的纤维形态结构.观察毛发的鳞片形状、厚度、密度、类型、边缘性状、截面、髓腔等特征.分析其异同特征,为仿生开发新型功能纤维提供实验基础和科学指导.
With both harsh climate and demand of lightweight apparel, more and more researches were focused on thermal insulation clothing. Beside wool/cashmere fibre, the other rare animal hairs have also being paid attention to in order to utilize directly or to become the imitative objects. As the sort of animals can survive in the harsh climate, their hairs are the key to keep them warm. Therefore, four kinds of cold-resistant animal's hairs, i.e. polar bear's, yak hair, sea lion's, and white-lipped deer' s, were observed by means of optical microcopy (OM) and scanning electron microscopy (SEM). The characteristics of the hairs of the cold-resistant animals were investigated, such as hair colour, scale density, scale thickness, medulla distribution and morphology of fiber cross-section. The experimental results show that there are some common characteristics to the cold-resistant animal's hairs. The conclusions may be used to provide some modification method for functional fibres, especially for thermalinsulation fibers.
