动物毛纤维的扫描电子显微分析

动物毛纤维的扫描电子显微分析 STUDY ON ANIMAL FIBERS BY SCANNING ELECTRON MICROANALYSER 朱绫 Zhu Ling first-author 本文利用扫描电子显微分析仪对一些动物毛纤维进行了形貌观察,并对其元素组成和分布进行了分析。研究表明,各种动物粗毛纤维鳞片形貌各有特征,但绒毛纤维的鳞片形状彼此接近,需要通过元素组成才能加以鉴别。X-射线能谱半定量分析的结果表明,各种动物毛纤维的元素组成有明显的差异。利用这些差异,不仅可以区分不同类型的动物毛纤维,而且也可以区分不同品种,不同地区和不同质量的同种动物毛纤维。这就有可能为动物毛纤维的分析鉴别提供一种较为客观、可靠的方法。 Wool and other animal fibers have been observed and measured by scanning electron microanalyser. The experiments show that each animal fiber has distinctive scales. The number of chemical elements containing in each animal fibeu and their contents are different from each other. The wool and angora rabbit fibers contain more kinds of chemical elemant than other animal fibers examined. Only the wool fibers contain detectable iron and that was not founded in other fibers. In the same kind of fiber content of sulfur in fine fibers is more than that in coarse fibers and sulfur content in the tip of fiber is less than the other parts of that. 1986-04-01 2021-04-01 4
