Technology for spinning 40<S> high tenacity vortex viscose yarn and vortex viscose yarn

Abstract

The invention provides a technology for spinning a 40<S> high tenacity vortex viscose yarn and the vortex viscose yarn. The technology for spinning the 40<S> high tenacity vortex viscose yarn is characterized in that an 80<S> ring viscose yarn is fed between front rollers of a vortex spinning machine and a vortex spinning spray nozzle; meanwhile, a wrapping viscose rough yarn is fed from rear rollers, drafted by four rows of rollers and converged with the fed 80<S> ring viscose yarn between the front rollers and the vortex spinning spray nozzle so as to be commonly twisted into a 40<S> fine yarn; the technology comprises an opening and cleaning procedure, a cotton carding procedure, a drawing procedure, a rough yarn procedure, a ring spinning procedure, a spooling procedure and a vortex spinning procedure. By the adoption of the technology for spinning the 40<S> high tenacity vortex viscose yarn, the combination of advantages of vortex spinning and ring spinning, i.e. less hair and high strength can be realized; meanwhile, during the vortex spinning procedure, the tension stability control prior to the feeding of a core yarn between the front rollers and the vortex spinning spray nozzle is realized via a mode that a filament tension control device and a filament guide frame in the shape of a circular arc are additionally installed; therefore, the uniformity of mixing the 80<S> ring viscose yarn fed between the front rollers and the vortex spray nozzle and viscose fiber fed from the vortex rear rollers and drafted by the four rows of rollers is improved, so that a finished yarn is perfected.

Description

technical field [0001] The patent of the present invention relates to the field of new spinning technology, specifically a 40 S High tenacity eddy current viscose yarn and its spinning process. Background technique [0002] Ring spinning, which achieves twisting through spindle rotation, is the most traditional spinning method, and it is also the most widely used and most common spinning method in the market. The technology is very mature. New spinning technologies, such as rotor spinning, air-jet spinning, etc., especially air-jet spinning, have completely changed the twisting mechanism of ring spinning by using high-speed swirling airflow to make fiber bundles false-twisted and wrapped into yarns, but these new spinning methods There is still no substitute for ring spinning in terms of raw material availability and overall yarn quality. Therefore, ring spinning is still the most important method of spun yarn production. However, this technology increases the amount of h...
