ANALYSIS ON THE IMPORTANT FACTORS INFLUENCING SPIRALITY OF WEFT KNITTED FABRICS (Pages : 8 - 14)

Single jerseys knitted fabrics were produced from different yarn count (26s/1, 28s/1, and 30s/1) using different stitch length (2.60mm, 2.75mm, 2.80mm and 2.85mm) with positive feed device in Jiunn long knitting machine. The fabrics were dyed by a winch dyeing machine, dried in compactor machine using selected parameters. The results showed that spirality% were lowest for 26/1 Ne, 28/1 Ne and 30/1 Ne knitted fabrics at stitch length 2.60mm, 2.75mm, 2.80 & 2.85mm before compacting and at stitch length 2.68mm, 2.73mm, 2.78 & 2.82mm after compacting respectively. 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.Download
