Abstract

The invention provides an elastic vortex-spinning core-spun yarn and a production method thereof. External covering fiber strands and core filament raw materials are adopted for producing the elasticvortex-spinning core-spun yarn through a vortex-spinning core-spun yarn spinning device, and the vortex-spinning core-spun yarn spinning device comprises a vortex spinning machine platform and a corefilament guiding device arranged on the upper portion of the vortex spinning machine platform; the vortex spinning machine platform comprises a front roller, a front leather roller (7) and a spinningspindle (8), and the front leather roller (7) and the spinning spindle (8) are matched with the front roller; in the processing direction of the core filament raw materials, the core filament guidingdevice sequentially comprises a core filament guiding frame, a core filament tension disc (16), a core filament guiding hook (15), a core filament tension control piece (14) and a core filament airflow guiding piece (13). The yarn made by means of the method can keep excellent characteristics of high vortex spinning efficiency, smooth cloth surfaces and good anti-pilling performance; the type of the core filaments of the vortex-spinning core-spun yarn is changed, and the yarn also has the advantages of good elasticity and elastic recovery performance, soft and comfortable handfeel and high yarn strength.

Description

technical field [0001] The invention relates to the field of spinning, in particular to an elastic vortex spinning core-spun yarn. Background technique [0002] Vortex spinning is a method of condensing and twisting fibers that have been opened into a single state by using the action of air vortex. Since the eddy current replaces the mechanical twisting and cohesion and does not require rotating parts, the structure is simple and the spinning speed is high, which is generally 6 to 7 times higher than that of ring spinning. [0003] As a relatively mature new spinning technology, vortex spinning has short production process, high production efficiency, and less labor. Its products have smooth surface, less hairiness, and good anti-pilling performance, which are favored by textile enterprises. In recent years, the varieties of vortex spinning core-spun yarns have been gradually developed to improve the strength and shape retention performance of ordinary vortex spinning yarns...
