Analysis on cross section structural parameter of blended yarn

To accurately describe the geometric size of fibers in blended yarns,blend ing ratio,and spatial d istribution and analyze the relationship between physical properties of blended yarns and these parameters,a new method is presented in this article.Take wool/viscose blended yarn as an example,the software ImageJ was used to analyze the slice image of blended yarn cross-section,includ ing quantitative description of the structural parameters such as blend ing ratio,relative rad ius of fiber d istribution,fiber content d istribution uniform ity.On this basis,the relationship between structural parameters and the quality of the blended yarn is analyzed briefly,and the values obtained match with practical results.This provides important guidelines for quality control of blended yarn in practice.
