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.

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.
