Examination of Knitting and Yarn Influence on the Shrinkage of Knitted Fabric by Factor Analysis

Abstract

The paper deals with the analysis of the influence of yarn kind, change of infeed yarn tension and applied relaxation procedure on the structural parameters and knitted fabric shrinkage respectively. The results were examined applying statistical standard methods and especially by factor analysis. The results show that a change of infeed tension does not significantly influence horizontal density at dry relaxation, but does at wet relaxation, whereas at vertical density the significance of the influence is determined at dry as well as at wet relaxation. The coefficient of stitch density is increased from dry towards wet relaxation, and the cause lies in a considerable increase of horizontal density and in a higher knitted fabric shrinkage respectively.
