Modified Two-strand Spinning Part I: Theory

Abstract

A modified two-strand spinning system is described in this study. This system differs from other two-strand spinning systems in that it has a pair of intennittent notch roller placed above the convergence point. The notch roller cyclically alters the number of twist in the two strands above the convergence point and increases the level of strand-twist in the folded structure below the convergence point. This leads to increased trapping of surface fibres so that the hairiness of the resultant yam can be reduced and its abrasion resistance improved. A mathematical analysis of this modified two-strand spinning system is presented in this part of the series.
