The knot strength ratio and loop strength ratio have been used as important factors in evaluating the knittability. Both the ratios increase with the increase in acrylic content and exceed the performance requirement limit for knitting. The knittability of acrylic-majority yarns is superior to that of cotton-majority yarns, although the acrylic- majority yarns are more stiffer. Additional advantages of acrylic-majority yarns are their lower twist liveliness, higher elongation, higher bulk and lower hairiness.
