双喂给双分梳转杯纺技术研究进展

转杯纺纱技术具有高速高产的优势,得到了广泛的应用,但传统转杯纺因单分梳辊的配置不适合纺制纤维性能差异较大的混纺纱,而近年来双喂给双分梳(DFO)转杯纺技术的提出为这类混纺纱开发提供了可能。概述了DFO转杯纺技术的发展历程,比较了其与传统单分梳转杯纺在纺纱器气流场分布方面的异同,探讨了2路独立喂入的纤维在纱线中的混合与分布情况,指出了DFO转杯纱质量提高的原因以及DFO纱线结构的特点。此外,综述了DFO转杯纺技术在纱线产品设计和面料开发方面的进展,展望了该技术未来的发展前景,指出DFO纺纱器的完善和颜色与结构变化花式纱的开发是其研发方向。

Research progress of dual-feed-opening rotor spinning technology

Rotor spinning technology has been widely used for its advantages of high speed and high yield, but traditional rotor spinning is not suitable for making blended yarns from fibers with different fiber properties due to the configuration of single opening roller. In recent years, the dual-feed-opening (DFO) rotor spinning technology has provided a possibility for the development of such blended yarns. To this end, the development process of DFO rotor spinning technology was reviewed and summarized in this paper. The similarities and differences of the airflow field distribution in the spinning unit between DFO and the traditional rotor spinning were compared. The mixing and distribution of two independently fed fibers for making yarns was discussed. Reasons for the quality improvement of DFO rotor spun yarn and the characteristics of DFO yarn structure were pointed out. Furthermore, the progress of DFO rotor spinning technology in yarn product design and fabric development was also reviewed, and the future development prospects of this technology were prospected. It is pointed out that perfecting the DFO spinning unit and developing fancy yarns with changes in color and structure are the directions of its research and development.
