摘要/Abstract

摘要：

针对传统型转杯纺因单分梳技术的限制只能纯纺或者混纺性能相近的纤维原料却难以生产纤维性能差异较大的混纺纱的问题,以及基于近年来双喂给双分梳新型转杯纺技术的研究,介绍了传统型转杯纺的成纱机制以及双喂给转杯纺技术的特点,并对比分析了传统型转杯纺纺纱器和双喂给转杯纺纺纱器的结构。通过数值模拟和样纱试纺实验,分析比较了传统型转杯纺和双喂给转杯纺转杯内部流场分布特征,包括转杯内涡流、气流速度以及压强分布,同时也进一步对比分析了2种转杯纺成纱系统所纺纱线的成纱结构及其成纱性能,验证了双喂给转杯纺纺纱技术的合理性和可行性。

Abstract:

In view of conventional rotor spinning's limitation which can only spin the fiber raw materials with similar properties of pure spinning or blending because of single carding technique, it is difficult to produce the blending yarn with large difference in fiber properties. Based on the recent research of dual-feed and dual-comb rotor spinning technology, this paper briefly introduced the yarn forming mechanism of conventional rotor spinning and the characteristics of dual-feed rotor spinning technology, and did the comparative analysis of rotor spinning machines' structure in the two rotor spinning systems. By means of fluid dynamics numerical simulation and sample yarn spinning test, this paper further analyzed conventional rotor spinning and dual-feed rotor spinning comparatively from the two aspects of the airflow distribution inside the rotor, which includes the vortex, airflow velocity and pressure, and the yarn performance. The research result verifies the feasibility and superiority of the dual-feed rotor spinning.

Key words: dual-feed rotor spinning, conventional rotor spinning, numerical simulation, airflow distribution, yarn performance
