Evaluation of Mechanical and Physical Characteristics of Eco blended Melange Yarns

The production and consumption of melange yarns are gradually increasing due to natural multi-colours and strong 3D fashionable eff ects.The raw material and chemical processing infl uence the environmental and textile values of the melange yarn.Organic cotton and regenerated cellulose fi bres are basic raw materials for eco-friendly production of yarns.In this study three diff erent regenerated fi bres are blended with organic cotton in three diff erent ratios to manufacture the blended melange yarns of two diff erent shade depths.Therefore, cotton-bamboo viscose, cotton-lyocell and cotton-SeaCell™ blended melange yarns with three blend combination 30/70, 50/50 and 70/30 are manufactured.All the dyed and grey components are mixed at the blow room.The aim of the study is to investigate impact of raw material and blend ratio on mechanical and physical characteristics of diff erent shade depth blended melange yarns.Better yarn characteristics with respect to yarn evenness, imperfections, hairiness, tenacity, elongation, coeffi cient of friction and diameter are achieved for lower shade depth melange yarn.In cotton-rich blended melange yarns, elongation, hairiness, evenness, total imperfections and diameter are noticeably worse for all the combinations.Statistical analysis shows signifi cant eff ect of blend type, blend ratio and shade depth on the all yarn properties.
