Development of Polylactic Acid Fiber Spandex Core Spun Yarn
Abstract：Processing of polylactic acid fiber spandex core spun yarn was discussed. Spinning method and key technology in each process of spinning polylactic acid fiber spandex core spun yarn on ring spinning frame were introduced. The process tests have been done in main processing parameters which influence the polylactic acid fiber spandex core spun yarn. The best optimization of yarn twist and pre-drafting ratio of spandex were selected through orthogonal test. Finally, 40.13tex(77dtex)polylactic acid fiber spandex core spun yarn could be spun successfully, the yarn quality could reach better level.
