Abstract:

In this study, relationships between yarn diameter/diameter variation and yarn strength were investigated. For this, we used 100% cotton combed ring yarns of nine types from the same blend which have three yarn counts with three levels of twists, as well as 100% wool worsted yarns of nine types which have nine different yarn counts and twist levels. The findings obtained were evaluated by correlation and regression analyses, and statistically significant correlation coefficients between yarn strength and yarn diameter/diameter variation were found. Furthermore, multiple linear regression models were established to allow the estimation of yarn strength from the other yarn parameters such as yarn diameter, diameter variation, twist, twist variation, capacitive and optical unevenness.
