Spirality of weft knitted fabrics: Part III— An innovative method for the reduction of the effect

Abstract

202-208The effect of partially detwisting steam-set yarns on spirality is studied. It is observed that partial detwisting reduces significantly and in some cases eliminates the spirality of weft knitted fabrics produced from singles ring-spun yarns. As this technique is applied, two phenomena appear that disobey the rules concerning the relationship of yarn twist direction, twist liveliness and fabric spirality, indicating that these three factors are inter-related with the yarn torque
