摘    要:对羊毛纤维弱节的几何形态特征,采用SEM观察进行了分类定义和表征。实际观察发现羊毛的弱节有纤维细颈和形态结构缺陷二类,其中形态结构缺陷主要是天然生长和人为加工中的畸变点和损伤点。弱节的几何长度为纤维直径的2-4倍,且弱节越多,纤维直径离散越大。同时分析了羊毛形态弱节的主要成因。

关 键 词:羊毛纤维  几何结构  形态特征  弱节

Morphological Characteristics of Wool Fibre Weak-links

Abstract:The geometrical morphology of the weak links on wool fibres has been described, classified and characterized by means of the observation of scanning electron microscope (SEM). The weak-links of wool fibres in geometrical structure involve two sorts of forms, i.e. the thin parts and the structural flaws of the fibres. The experimental results from a series of the SEM photographs indicate that i) the natural defects and artificial damages are the main reason resulting in the structural flaws; ii) the geometric dimension of the fibre weak-links are 2-4 times as big as the average fibre-diameter; and iii) the more the morphological structural weak-links are, the large the variation of the fibre diameter and the lower the fibre strength and extension.
Keywords:weak-link  wool  fibre  SEM  morphology  geometrical structure
