摘要
探讨聚乳酸纤维包芯纱的生产工艺。阐述了在环锭细纱机上纺制聚乳酸纤维包芯纱的方法及各生产工序的工艺要点,并通过正交试验确定了纱线捻度和细纱后区牵伸倍数的最优工艺配置,最终顺利纺制出了21.4 tex(55.6 dtex)聚乳酸纤维包芯纱,质量达到了较好水平。
Processing of polylactic acid fiber core spun yarn was discussed. Spinning method and key technology in each process of spinning polylaetic acid fiber core spun yarn on ring spinning frame were introduced. The best optimization of yarn twist and multiples in back zone were selected through orthogonal test. Finally 21.4 tex（55.6 dtex）polylactic acid fiber core spun yarn can be spun successfully,the yarn oualitv can reach better level.
