羊毛、羊绒纤维鉴别方法综述

Identification methods descriptions of wool and cashmere

主要从特征参数法、溶液法、光谱分析法、DNA法、生物芯片法进行概括和总结。采用光学显微镜或电子显微镜提取纤维直径、鳞片密度、鳞片边缘高度特征参数,通过统计学原理进行分类可以达到预期效果;高锰酸钾溶液对于纤维的破坏程度较明显,处理后的溶液通过测量失重比、拉伸强度等信息进行比较区分;光谱鉴定中标准光谱与待测光谱做差,其阈值的合理选择可以快速进行识别;DNA法与生物芯片法原理相似,同属于生物信息提取分类;运用X射线衍射进行绒毛结晶情况分析;定性检测拉细羊毛与羊绒区别在于细度、弹性、卷曲度等性质的鉴别。

This paper summarized generalize from the feature parameter method, the solution method, spectroscopy, DNA, bio-ehip method and summary. Extracting the fiber diameter, the density of scale, scale edge height parameters of an optical microscope or electron microscope can be classified by statistical principles to achieve the desired effect. Potassium permanganate solution for the damage obvious fibers after treatment was compared by measuring the weight loss of tensile strength and other information for comparison to distinguish. Spectral identification standard spectra measured spectra do worse, its threshold is a reasonable choice can be quickly identified. DNA biochip law and the principle of law is similar to belong to the same biological information extraction classification. The use of X-ray diffraction analysis crystalline fluff. The use of X-ray diffraction analysis crystalline fluff. Qualitative detection of fine wool and cashmere pull difference lies in the identification fineness, flexibility, curl and other properties.
