摘要: 雪尼尔纱的形态结构参数包括雪尼尔纱的线密度,饰纱的排列密度,雪尼尔纱的直径和雪尼尔纱的捻度等。为了探讨雪尼尔纱形态结构的调控机理,以前罗拉的线速度,饰纱的卷绕速度和隔距片的宽度作为设计参数,研究了基于雪尼尔纺纱机改变雪尼尔纱饰纱排列密度和饰纱宽度,实现调控雪尼尔纱形态结构的纺纱工艺,设计并纺制了不同规格的雪尼尔纱。结果表明:通过改变前罗拉线速度和饰纱卷绕速度,可以在纺制同一根雪尼尔纱时连续变化饰纱的排列密度,呈现出不同的形态结构。其中,改变前罗拉线速度时,同一雪尼尔纱中饰纱的排列密度倍率最高可达3.3倍;改变饰纱卷绕速度时,同一雪尼尔纱中饰纱的排列密度倍率可达到4倍;通过改变隔距片宽度,可以纺制不同直径宽度的雪尼尔纱。本文研究了雪尼尔纱形态结构参数的调控机理,实现拓宽雪尼尔纱的纺制工艺从而提高雪尼尔产品的市场竞争力。

Abstract: The morphological and structural parameters of the chenille yarn include the linear density of the chenille yarn, the arrangement density of the decorative yarn, the diameter of the chenille yarn and the twist of the chenille yarn. In order to explore the regulation mechanism of the chenille yarn′s morphological structure, the linear speed of the former roller, the winding speed of the decorative yarn and the width of the spacer were taken as design parameters. Based on the chenille spinning machine, the spinning technology was studied to change the arrangement density and the width of chenille yarn ornaments, and to realize the control of chenille yarn shape structure. The chenille yarn of different specifications is designed and spun. The results show that by changing the linear speed of the front roller and the winding speed of the decorative yarn, the arrangement density of the decorative yarn can be continuously changed when the same chenille yarn is spun, showing different morphological structures. Among them, when the linear speed of the front roller is changed, the arrangement density ratio of the decorative yarn in the same chenille yarn can reach up to 3.3 times, and when the winding speed of the decorative yarn is changed, the arrangement density ratio of the decorative yarn in the same chenille yarn can reach 4 times. By changing the width of the spacer, chenille yarns of different diameters and widths can be spun. The regulation mechanism of chenille yarn's morphological and structural parameters was studied, and the spinning process of chenille yarn was broadened to improve the market competitiveness of chenille products.
