Tensile and Elastic Performance of Cotton/Lycra Core Spun Denim Yarn

摘要

Various cotton/lycra core spun yams are prepared in modified ring frame. The core of the yarn consists of a 70 dtex lycra filament and sheath consists of staple cotton fibers. The cotton/lycra core spun yarns are explored for the suitable application of stretch denim fabric. The tensile and elastic performance properties of the prepared stretch yarns are evaluated. The influence of various parameters viz. pre-load, linear density, stretch percentage, twist multiplier and applied load during tensile testing, on the properties of the stretch yarns are investigated by employing a full factorial design and statistical analysis.
