This article presents a comparative analysis of the properties cotton yarn spun on aerodynamic compact spinning and open-end rotor systems. Yarn samples with linear density 50 Tex, 37 30 25 20 Tex were both systems using same finisher drawn sliver medium staple which produced by specific mixing. The quality parameters such as mass variation, imperfection index, hairiness, tensile behavior (stre...

In the scope of study, effect fiber blending ratio, yarn count and twist coefficient on migration, packing density diameter cotton/acrylic blended yarns were investigated. The samples with 75-25%, %50-50%, 40-60% cotton-acrylic ratios produced three different numbers; 20/1 Ne, 24/1 30/1 Ne coefficients; 3.5 α, 4 4.5 α. Thus, totally 27 obtained. cross-sectional sliced microtome. image frames cr...

The problem of yarn breakage during spinning is quite serious, but it is difficult to predict the number of yarn breakages, because the tension and strength of the yarn always vary. The author has used simple mathematical models of the variation of the tension and the strength of the yarn, and calculated the probability of yarn breakages. The result has shown that the variation of the yarn stre...
