Abstract

Spirality is particularly serious problem for single jersey knitted fabrics due to their asymmetrical loop formation. This paper focuses on spirality of the single jersey knitted fabrics as key aspects. This paper investigates the different studies such as effect of Yarn tension, No. of feeders and Stitch length on the spirality of single jersey knitted fabrics. The paper also explicitly determined the theoretically approach of the causes and remedies of spirality. The paper also focuses on the effect of fabric weight on the spirality of single jersey fabrics at both stages i.e. gray and finished state. The results of this study have concluded that the spirality is increases strongly when increasing the no. of working feeders with constant machine diameter. The result also concludes that the stitch length and yarn tension is also influences on fabric spirality. There is direct relationship of fabric spirality and yarn tension is observed by keeping other factors are constant. The study also concludes that stitch length is inversely proportional to fabric spirality. The fabric spirality is minimized up to 50% after the finishing process as compared to its gray stage spirality.

Introduction


The ever increasing demand of knitted apparels has attracted attention in global niche market. In comparison to woven garment, around 50% of the clothing needs are met by the knitted goods. It is well known that weft knitted fabrics tend to undergo certain dimensional changes that causes distortion in which there is a tendency of the knitted loops to bend over, causing the wales to be at diagonal instead of perpendicular to the courses.
