Abstract


Jet vortex spinning is the use of high-speed whirling airflow twisted fibers shall article spinning method, which is characterized by fibers shall be in the process of twisting the free end is formed, final true twist yarn. Its spinning speed, less hairiness, special number, spun in cotton products, more and more attention has been paid. This spinning method using a high-speed airflow auxiliary roller drafting fiber bundles were separated, take full advantage of drafting good control of fiber, fiber straight and parallel good advantages than the general open-end spinning licker opener separation fiber, fiber separation straight parallelism, the advantages of fiber damage, more conducive to improve into yarn fibers arranged in shape and strength of yarn. Meanwhile, this method uses the high-speed whirling airflow to twist the fiber shall strip the absence of the restriction of the high-speed rotary member, which can achieve high-speed spinning. Murata No. 861 is based on such spinning machine spinning method, this model in our country, only less than 10 units. Fewer due to the introduction of the machine, the time is short, domestic models are not yet mature. This paper describes the jet vortex spinning yarn and yarn mechanism; using tracer fiber, of Hastelloy slices yarn structure method of jet vortex spinning line structure study and draw the yarn structure model. That: the central part of the core of untwisted or twisted fiber, about 30% of the yarn, the outer surface of the helical twisting fibers. The outer helical fiber into two parts, one part is a single fiber to the straight state twisted yarn core, the other part is a hook or twisting the folded state in the yarn on the surface, both the proportion of about 50% each. Surface twisting fibers from the inner to the outer layer is directional, but internal and external transfer phenomenon; experiments, the comparative analysis of the jet vortex spinning and ring spinning yarn properties and fabric performance. : MVS yarn strength is slightly lower than the ring-spun, pure cotton yarn is generally about 90% of the ring spinning, chemical fiber or blended product strength can be achieved over the general ring spinning, and other indicators to be superior to the general ring spinning, especially the hairiness performance, greater advantage than ring spinning some yarn to achieve the level of compact spinning. MVS yarn made knitted performance close to the decline in strength on cotton products, polyester cotton products are almost no effect; wear resistance, drape, pilling excellent compared with conventional ring yarn ring-spun fabric; anti-crease performance than ring-spun fabric; breathable and warm little difference between the two. Content, the paper mainly includes five parts: The first part of the development and classification of new spinning the jet the Vortex Spinning development and research status at home and abroad and the topics of the purpose and significance of research to do a brief overview; second part describes the mechanism of the jet vortex spinning process of the yarn and yarn; third part compares the performance of jet vortex spinning yarn spinning method; fourth part is the analysis of the structure of the jet vortex spinning line and its impact on The performance impact; fifth part of the comparative analysis of the performance of the jet vortex spinning fabric with ring yarn fabric.
