The Effects of S, Z and S/Z Twist Yarn and the Number of Feeders on Spirality of Single Jersey Knitted Fabric

Abstract

This paper investigates the effect of fabric S, Z and S/Z twist yarn and different numbers of feeders, 32, 64, 96 on spirality of single jersey knitted fabric. The hypothesis is set for as for increasing numbers of feeders may result in the higher degree of spirality of the fabrics. In addition, the yarn twist direction may add more effect to the spirality value on the single knitted fabrics. All fabric samples are dyed, analyzed and measured for values of spirality through course and wales in each significant step that may have an effect on spirality value. The objective of this study is to explore and develop the factors that determine the least angle of spirality. The results of the experiment shows S twist yarn has the highest degree of spirality followed by the Z twist yarn and S/Z gives the lest degree of spirality.
