Lutai Textile Company Limited, Zibo 350074, China In this study, combed ring spun and compact spun cotton yarns with different counts were selected from different textile mills to conduct singeing treatment. Yarn properties including hairiness, fineness, unevenness and tensile properties were tested after the treatment and the results were compared with those before treatment. Hairiness was greatly removed after singeing, especially for short hairs with length less than 3 mm. Compact ring spun cotton yarns showed higher tex values and lower weight loss than combed ring spun cotton yarns under the same counts. Coefficient of variation of yarns increased slightly after singeing treatment. The unevenness of yarn was divided into two parts: basic unevenness of yarn body and hairiness unevenness, to explain the worse yarn evenness after singeing treatment. In this way, the effect of singeing on yarn properties was investigated thoroughly so as to improve yarn quality with less hairiness and good evenness.
Key Words: combed ring spun yarns compact spun yarns hairiness singeing unevenness
