A Method For Making A Multifilament Polyolefin Yarn As A Continuous Process On A Single Melt Spin Draw Wind Machine And The Multifilament Polyolefin Yarn

Abstract: Invention discloses a method for making polyolefin multifilament yarn mimicking natural wool on a single melt-draw-spin machine and a multifilament yarn/fiber mimicking natural wool. The key steps of the method include said feeding the raw material into an extruder to convert them into a fluid melt, passing the said fluid melt through spinneret, where the polymer comes out in form of continuous filaments, cooling the filaments through a blast of cross-flow cold air whereby plurality of filaments is bundled together to form a multifilament yarn, applying spin finish via a nozzle to impart further processability of yarn, heating and stretching the said spin finished yarn through a series of godet rolls wherein multifilament yarns are slightly fused as per requirement in controlled/ random distribution to create a loose web like structure. The yarn has random binding/fusing and slight wave and a yarn to metal coefficient of friction between 0.20 to 0.30.
