Sažetak
An investigation of yarn breakage, related to thin places in the yarn, by using digital-signal processing on a personal computer is presented. By examining the stored measured results from an evenness tester and yarn-strength tester, an analysis of thin places and breakages at these points is made. Only yarn thin places in which the mass cross-section is less than -40% of the mean mass of the yarn cross-section per measured length (L = 180 m) are taken into consideration in the analysis. Through correlation analysis, a direct dependence of thin-place occurrence and yarn breakage at that point is established. It is found out that, in 61% of the samples tested, yarn breakage occurs at such a thin place. It is also confirmed that the mass of the yarn cross-section at the point of yarn breakage is proportional to the breaking force at the yarn section in question.
