Spirality in Plain-Jersey Fabrics Knitted of Three-Ply Cotton Yarns
The effects of some factors on the Spirality in plain jersey fabrics knitted of three-ply cotton yarns are investigated experimentally, and the following equation is derived statistically: PS(%)=(a√ +b)Sn+c/l+d where PS(%) is the percentage spirality in cotton plain jersey fabrics, Sn the number of snarls per yarn length of 25cm, l the loop length in mm, and a, b, c and d are constants. Let PS(%) and Sn be positive for the Z direction and negative for the S direction.The values of a and b are approximately constant and independent of the knitting machine speed and the method of the relaxation treatment used. On the other hand, the values of c and d are dependent on them. The values calculated from this equation agree well with the experimental values.
