Quality optimization of ring spun yarns produced from blends of regenerated cellulosic fibres with cotton and polyester

Abstract

Regenerated cellulosic fibres are mainly used with the blends of cotton and polyester with different proportion on different spinning systems to meet specific consumer demands in textile industry. This study conducts the properties and quality optimization of 19.7 tex ring spun yarns made from Viloft®, ProModal® and Bamboo regenerated cellulosic fibres blended with polyester and cotton at different proportion (100%, 67-33%, 50-50%, 33-67%). Yarn properties such as tensile strength and elongation, unevenness, imperfection index and hairiness were evaluated and compared to determine the effects of blend type, fibre type and blend ratio. Furthermore, numerical optimization method was developed to estimate optimum yarn quality parameters for the best response variables of tensile strength and elongation, unevenness, imperfection index and hairiness properties.
