摘要：

针对目前国内外生产的段彩纱色彩变化较单一,且现有工艺无法精确控制纱线段彩长度及颜色等问题,通过环锭数码纺纱机数字化控制分段时间内纤维组分比例的变化,实现段彩纱分段长度上色彩变化的多元化和长度的可控性,并以红、黄、青3根粗纱依次组合进行耦合牵伸为例,给出了三通道环锭数码纺纱机实现数控混色纺纱的机制。设计了CMY三基色等量梯度混色的数学模型并运用Photoshop软件对混色矩阵进行了表达,将混色矩阵作为段彩纱分段长度上色彩选配的依据,绘制了三色、六色、七色段彩纱的外观模型并纺成纱线。结果表明:改变纺纱锭速、捻系数、段彩周期长度、色纤维混纺比,均可得到段彩纱条干及断裂强度值相对较优的纱线。

Abstract:

In view of the fact that the color changes of the segment yarn at home and abroad is relatively single, and the production process cannot achieve accurate control of the color and length of the segment colo, a digital spinning technology was used for the digital control on the change of fiber composition ratio in the segmentation time, the diversification and length controllability of the color change on the segment length of the segment color yarn. The spinning mechanism of the three-channel digital ring spinning was proposed, taking the combination of the three rovings of magenta, yellow, and blue combined in a sequential manner as an example. A mathematical model of CMY three basis color with equal gradient changes was designed. Photoshop software was used to express the color matrix. The color of the segment color yarn was selected on the basis of the mixed color matrix, and the appearance model of tri-color, six-color, seven-color segment colored yarn were drawn. The results show that the segment colored yarn with optimum evenness and strength could be spun by adjusting spinning speed, twist factor, period length of segment color and color fiber blending ratio.

Key words: segment colored yarn, digital spinning, colour mixture simulation, spinning process
