精梳工艺对涤粘混纺纱质量的影响
Influence of combing process on polyester viscose blended yarn quality
摘要
Abstract
In order to evaluate the application effect in the combing process processing of polyester viscose blended yarn,polyester viscose blended yarns with blending ratios of 65/35,50/50 and 35/65 were spun by using combing process and carding process respectively.The quality of fiber sliver and yarn with the two blending processes were tested.The test results showed that compared with polyester viscose drawing sliver,eveness CV value of polyester viscose combed sliver was slightly decreased,nep,impurities and short fiber content below 16.5 mm were significantly decreased,the upper quartile length of the fiber was slightly increased.Compared with polyester viscose carded yarn,the eveness CV value and 3 mm hairiness index of polyester viscose combed yarn were reduced,neps,thick places and thin places were greatly reduced,and the breaking strength was increased.With the increase of viscose fiber,the quality of polyester viscose blended fiber sliver and yarn showed a deteriorating trend.It is considered that the combing process can significantly improve the quality of polyester viscose blended fiber sliver and yarn.关键词
