摘要:
Spinning Technology of water-soluble vinylon hollow yarn was discussed.The optimum spinning technology parameter of water-soluble vinylon yarn was systematically analyzed.Using water-soluble vinylon yarn covered by medium cotton,water-soluble vinylon core spun yarn was spun.Practice shows that when spinning wa-ter-soluble vinylon yarn,higher temperature water-soluble vinylon fiber mixed with a certain proportion of medi-um and lower temperature water-soluble vinylon fiber can speed up the dissolution of vinylon in fabric and im-prove the dissolution effect of vinylon fiber.Water-soluble vinylon is easily to be swelled with water,when spin-ning water-soluble vinylon yarn,some technology measures should be adopted such as strict control temperature and humidity,more opening & less beating,less noil & preventing broken,biger gauge,heavier pressure,lower twist and reducing the speed of spinning frame."Smaller-twist,lower-speed"technology principle is adopted when spinning water-soluble vinylon core spun yarn.It is considered that fabric using water-soluble vinylon hollow yarn has better thermal insulation,hygroscopicity and skin-friendly.%探讨水溶性维纶中空纱的纺纱工艺.系统分析了水溶性维纶纱的最优纺纱工艺参数.利用水溶性维纶纱外包细绒棉,纺制水溶性维纶包芯纱.实践证明:纺制水溶性维纶纱时,高温水溶性维纶中混入一定比例的中低温水溶性维纶,可以加快织物中维纶的溶解速度,改善维纶水溶效果;水溶性维纶遇水易溶胀,纺水溶性维纶纱时要严格控制温湿度,多松少打,少落防断,大隔距,重加压,低捻度,降低纺纱速度;纺水溶性维纶包芯纱时宜采用"小捻度,低速度"工艺.认为:水溶性维纶中空纱织物保暖隔热、吸湿性和亲肤性好.
