摘要
为了解决棉织物散湿性不好的问题,在环锭细纱机上使用涤纶热熔丝和维纶水溶丝与纯棉粗纱进行包缠纺,再将该包缠纱在烘箱中进行110℃的高温处理,使纱线表面的涤纶热熔丝先被熔化,冷却后的产物将维纶水溶丝和纯棉纱体进行固定,再进行高温水浴溶解维纶水溶丝。试验结果表明:维纶水溶丝溶解空出的部位形成沟槽,且由于涤纶热熔丝熔化冷却后的产物固定这个空间,因此纱线的表面会形成比较稳定的沟槽结构。沟槽结构的存在会形成毛细效应,能加快液态水的导湿,有利于水蒸气的排放,其中滴水扩散时间平均减少25.04%,30 min时芯吸高度平均提高19.48%,透湿量平均提高11.56%。
In order to solve the problem of cotton fabrics with poor moisture dissipation,polyester thermal melting filament and vinylon water-soluble filament were used in ring spinning frame to produce fasicated yarn with pure cotton roving.Then,the fasicated yarn was treated with 110℃chamber,so that the surface polyester thermal melting filaments were melted firstly then the outcome after cooling could fix the vinylon water-soluble filament and pure cotton yarn body.After that,the vinylon water-soluble filaments were dissolved in water bath at higher tempera⁃ture.The experimental results showed that groove structure was formed after vinylon water-soluble filaments were dissolved.Moreover,because the space was fixed by the cooling outcome of the melted polyester thermal melting fila⁃ments,stable groove structure was formed on the surface of the yarn.The existence of the groove structure led to the capillary effect and it could speed up the wet conduction of liquid water.It was beneficial to the discharge of wet steam.The average diffusion time of water drops was decreased by 25.04%.30 min wicking height was increased by 19.48%in average.The amount of water vapor transmission was increased by 11.56%in average.
