Abstract

The single yarn strength CV value is one important index to measure the quality of yarn. Taking pure cotton and polyester cotton blended yarn as research objects, in this article, we systematically analyze the effects of some factors such as raw material blended ratio, yarn unevenness and twist unevenness on single yarn strength CV value, and use the mathematic analysis method to obtain the relationships between various influencing factors with single yarn strength value, and the result possesses directional meanings to enhance the quality of yarn in actual production.
