Abstract

The invention belongs to the field of yarn processing and provides an air-jet vortex spinning device for spinning low-tow yarn by twisting fibers with free tail ends using high-speed swirling air flow. The device comprises a guide pipe, a guide needle, an air storage cover, a twisting nozzle, a first air storage room, a second air storage room, an exhaust cover, a tight spindle, a vortex tube anda vortex tube support. By additionally arranging the guide needle and the tight spindle and improving the structures of the twisting nozzle and the vortex tube and the process, the device can effectively lower the tow rate in the spinning process to obtain high-quality yarn with less hairiness and less thin places, and can simultaneously improve the utilization rate of material and lower the yarnproduction cost.

Description

Technical field: [0001] The invention belongs to the textile field and provides a device for effectively reducing the tow rate of air-jet vortex spinning. Background technique: [0002] Airflow is widely used in the field of textile processing. During the spinning process, airflow is often used to transport, condense and twist the fibers. The use of air-twisted fibers to form yarns overcomes the shortcomings of high inertia caused by high-speed rotation of twisting parts, not only can greatly improve twisting efficiency, but also can greatly increase spinning speed and reduce energy consumption. However, the control of airflow on fibers is not as strong as that of machinery on fibers. Under the action of high-speed airflow, some fibers will break away from the control of airflow and be discharged with the airflow to form toff, which will greatly reduce the utilization rate of raw materials and increase the production cost of yarn. The existing air-jet vortex spinning techn...
