新型全聚赛络混纺纱的成纱质量

为研究新型全聚赛络混纺纱成纱性能，采用一根5.0g／10m 精梳棉粗纱与另一根3.4g／10m涤纶粗纱在细纱工序进行全聚赛络混纺，纺出4种细度的棉／4 涤（60/40）新型全聚赛络混纺纱，并与单根混纺粗纱喂入所纺出的纱进行成纱质量对比；运用哈氏切片器，切取8种混纺纱线样本，在MOTTC B1型显微镜下观察纤维的分布状况，结合汉密尔顿指数分析方法，得到每种混纺纱内纤维的分布规律及内外转移趋势。结果表明：新型全聚赛络混纺纱的单纱条干CV值、断裂强力明显优于环锭混纺纱，且毛羽少；从单纱截面图得出，新型混纺纱中涤纶向纱芯转移呈现棉包覆涤纶的趋势，而环锭纺混纺纱中涤纶分布比较随机。

Yarn quality of novel blended spinning based on complete condensing siro-spinning

In order to research a novel complete condensing siro-spinning yarn, a new complete condensing siro-spinning yarn which adopted a 5.0g /10m combed cotton roving and a 3.4g/10m polyester roving are blended together in spinning process, four kinds of cotton/polyester (60/40) blended yarns were produced, and comparison is performed on single cotton yarn quality and cotton/polyester (60/40) blended yarn spun by ring spinning feeding in single blended roving; and the eightkindsof blended yarn samples were cut by a Harrington slicer. The MOTTC B1 microscope was adoted to observe distribution conditions of the fiber, and combined with the Hamiltion migration index method to acquire distribution reles of fibers and the internal and external migration trends. The results show that the CV value and single yarn breaking strength of novel complete conednsing siro-spinning blended yarn is superior to the conventional ring spinning blended yarn, and less bairiness; andfrom dingle yarn cross section diagram, itcan be concluded that the polyester fibers in the novel siro-spinning blended yarn are transferred to the yarn core and presents thetrend of cotton cated polyester, but conventional blended yarn gas more random distribution of polyester fibers.
