Abstract

The invention relates to a method for detecting compositions and a structure of composite fiber based on polarizing microscope analysis, which adopts a method based on polarizing microscope analysis to perform composition detection and structural analysis on composite fiber containing two or more compositions. The method comprises the following steps: firstly, preparing a fiber specimen to be tested into a sample wafer which can be observed under a polarizing microscope; placing the sample wafer under the polarizing microscope for detection; and analyzing an acquired fiber specimen image, and determining internal compositions and a structure of fiber to be tested by combining an Michel levy chart. The method is a physical detection method, adopts completely pollution-free detection, and meets the development trend of energy conservation and environmental protection. The method has the advantages of simple and convenient operation, high efficiency, high precision, low detection cost, and convenient popularization and application.

Description

technical field

[0001] The invention belongs to the technical field of textiles, in particular to a method for detecting composite fiber components and structures based on polarized light microscope analysis. Background technique

[0002] In recent years, composite fibers, that is, fibers containing two or more components, have been widely used in various fields instead of single fibers. Therefore, component identification and structural analysis of composite fibers have become increasingly prominent demands. At present, the methods for detecting the composition of composite fibers are mainly chemical dissolution method and infrared spectroscopic analysis method, but both have the disadvantages of complicated operation and high cost, especially the chemical method is easy to pollute the environment, and these two methods cannot confirm the composition of each component inside the fiber. structural relationship. Another cross-sectional projection method is used to analyze th...
