摘　　要：针对包芯纱在纺制过程中易出现"露丝"的现象,将全聚纺和赛络纺技术用于纺包芯纱,通过合理设置工艺参数,改善包芯纱的包覆效果,提高纱线综合质量。本文以棉氨包芯纱为例,在经过全聚纺改造的QFA1528细纱机上加装芯丝喂入装置后分别纺制29.2 tex/44.4 dtex和14.6 tex/44.4 dtex棉/氨纶赛络包芯纱,并选择导丝轮位置、粗纱中心距、芯丝预牵伸倍数、细纱捻系数4项工艺参数,采用控制变量法分别纺纱并观察包覆效果,分析对比其对包覆效果的影响。结果表明:4项参数在一定范围内设置均不会出现"露丝"现象;导丝轮位置影响芯丝在纱线横截面中的位置,粗纱中心距、芯丝预牵伸倍数、细纱捻系数对纱线包覆效果无显著影响。In the spinning progress of core-spun yarn, it often occurs that the cotton staple fibers can＇t cover the core filaments evenly and completely. Applying complete condensed spinning and Siro-spinning to core spun yarn spinning and setting proper process parameters can improve the covering effect significantly. This paper took cotton spandex core spun yarn as an example, 29. 2 rex/44. 4 dtex and 14. 6 rex/44. 4 dtex cotton spandex core-spun yarn were spun on the QFA1528 ring spinning machine, respectively, in which the complete condensing spinning system was equipped. Four spinning parameters including godet wheel position, strand spacing, yarn twist factor and pre-draft multiple of spandex filament were selected as the optimum parameters. Then, the covering effects were compared and influence factors were analyzed. The results indicate that staple fibers can cover the core filaments evenly when the selected parameters were set in a reasonable range. The godet wheel position can affect the core f
