EFFECTS OF YARN TWIST ON THE SPIRALITY OF PLAIN KNITTED COTTON FABRICS (Pages : 92 - 97)

Spirality is a particularly serious problem for plain knitted fabrics due to asymmetric loops. This study investigates the relationship between the spirality of plain cotton knits and yarn TPI. The experimental results show that the TPI of cotton yarn is the most important factor influencing fabric spirality. Relaxation treatment also shows significant effects. In general, increasing the twist factor of cotton yarn increases the angle of spirality. The experimental results demonstrate that relaxation treatment in water decrease the angle of spirality. The experimental data also lead to the derivation of empirical presentation linking the angle of spirality to the TPI of cotton yarn and loop length in both the dry relaxed and simulated industrial relaxed states. The work thus gives an advantage to solve spirality problem by using suitable TPI against stitch length and relaxation treatment.Download
