自循环多片段转杯纺混色纯毛纱生产方法及其面料特征

Spinning method and fabric characteristics of self-circulating multi-section rotor spinning color-blended pure wool yarn

提出了多色纯毛纱混色配比和线密度的在线调控方法,在三通道转杯纺纱机上实现在PLC控制系统驱动下各给棉罗拉速度按照纺纱工艺要求实时变动,通过控制3类纤维条的喂给速度,实现自循环多片段转杯纺混色纯毛纱的生产,优化了纺纱工艺,纺制出不同颜色的多片段渐变色毛纱、段彩毛纱和彩节毛纱,并对纱线性能及其针织面料风格特征进行分析。单根纱线上色彩的自由转换,为通过毛衫整体图案与织物组织结构的互映设计,实现毛衫的一体化快速设计与生产提供了有效方法。

By controlling the feeding amount and feeding ratio of the three feeding rollers with Program Logical Control system under the requirements of yarn spinning parameters,it was possible to dynamically configure the final yarn density of the rotor spinning and the blending ratio of three components to produce multi-segment gradient yarns,segment-color yarn,and segment-color slub yarn.The spinning parameters were optimized.Yarn properties and knitting fabric characteristics were analyzed.The free conversion of the color on the single yarn realized the integrated rapid design and production of the sweater by the mutual design of the overall pattern of the sweater and the structure of the fabric.
