摘要:

为得到多组分纤维经过并条混合后在混纺纱条内的分布情况,以预测混合纱条的混合不匀率、条干不匀率等质量指标,通过并条混合制备混纺纱条,采用MatLab软件模拟多组分纤维在并条混合过程中的运动状态,并设计可视化操作平台构建并条混合仿真与控制系统。将系统仿真结果与实验结果进行对比。结果表明:随着并条混合工艺参数的变化,二者趋势具有很好的一致性,且模拟过程快速,直观可视。该系统可用于对混纺纱条形态和质量的预测与调控,为实际生产中的工艺参数优化提供参考。

Abstract:

In order to obtain the distribution data of multi-component fibers in the blended yarn after the blending process, and to predict the quality indexes such as the blending irregularity and the unevenness of the sliver, MatLab software was used to simulate the motion state of the multi-component fibers in the process of sliver blending, and a visual operation platform was designed to build a simulation and control system. The simulation results were compared to the experimental results, revealing good agreements with different process parameters for blending. The simulation process is fast and visual. This system accurately predicts and control the shape and quality of blended yarns, and the work provides reference for the optimization of process parameters for practical production.

Key words: sliver blending, fiber distribution, blending irregularity, evenness of yarn, simulation
