Direct determination of yarn snarliness

Abstract

23-28The formation of snarls that takes place in the yarns in post-spinning processes, such as winding, warping, weaving and knitting, has been studied. This defect is due to the excessive yarn twist liveliness (torsional buckling) and causes great trouble to the manufacturers of yarns and fabrics. Biased testing techniques are used for the measurement of this defect. A snarling testing apparatus PRIANIC and an unbiased testing technique have been developed and are reported. The investigation of factors such as yarn package form, yarn twist factor, time elapsed between production and processing stages of yarns and yarn conditioning show the significant role they play in the reduction of yarn snarliness. </span
