Yarn image and analysis

Dec 6, 2015

See topic yarn image, can think of it has to do with mathematics. With yarn hairiness index and twist yarn image of two important indicators. Research of cotton yarn hairiness index and twist on the wear performance of influence, we adopt CTT yarn performance tester, cotton yarn was simulated under the high speed running state and wear parts, and tests the different density line, hairiness index and the twist of yarn performance. Through regression analysis, found the cotton yarn under the condition of the same density, its abrasion performance index of yarn hairiness and twist with a significant linear relationship, and hairiness index on the wear performance influence is greater than the twist of yarn abrasion performance impact.

   Make the yarn data measured, into yarn image, get a regression model. Through the establishment of regression model is not hard to see, in cotton yarn, the density of the conditions of uniform and same specification given conditions, the wear properties of cotton yarn hairiness index and twist a significant linear relationship, and gross margin index and twist effect on the properties of cotton yarn abrasion are also significant. But for the same density of cotton yarn, regression model and the twist of yarn hairiness index in the performance impact of the size is different. In order to compare the size of each variable, and the sample data in the standardization, the absolute value of standardized regression coefficients are obtained. 

   Of course, both yarn image, and the actual data, standardization of hairiness index coefficients is greater than the twist after, explain to the abrasion performance of the cotton yarn hairiness index influence is greater than the twist. In addition, the coefficient is of hairiness index of enhanced with the decrease of the yarn density, in turn, that is to say, with the decrease of the linear density, the degree to which the abrasion performance of the cotton yarn hairiness index will increase. In the actual production, therefore, can by controlling the yarn twist and hairiness situation to improve the wear performance of the cotton yarn.
