Description

Vortex spinning vortex tube

Technical Field

The utility model relates to a vortex spinning field, in particular to vortex spinning vortex tube.

Background

The spinning principle of vortex spinning is that sliver which finishes drawing is supplied to a drafting device, fiber bundles drafted by a roller drafting device are output from a front roller jaw and enter a spinning nozzle along a spiral fiber guide channel under the action of axial airflow at the inlet of the spinning nozzle. The outlet of the spiral fiber guide channel is provided with a needle-shaped twist-stopping piece, and the fiber bundle is bent at the needle part, so that the fiber bundle is introduced into the vortex chamber in a state of not adding twist. The leading end of the fiber bundle is drawn into a yarn passage in the spindle by the dragging action of the formed yarn and twisted into the newly formed yarn as a yarn core. The tail end of the fibre remains in the fibre guide channel while being gripped by the front roller nip. When the tail end of the fiber is not held by the front roller jaw any more, the tail end of the fiber is not kept in the fiber guide channel under the centrifugal action of the air vortex in the spinning nozzle, but is radially dispersed by the rotating airflow at the spindle inlet, is laid on the conical surface at the front end of the spindle under the driving of the air vortex, rotates along with the air vortex, is wound on the subsequent yarn and is output through the channel of the yarn in the spindle. The yarn formed is composed of a yarn core formed by approximately parallel untwisted fibers and fibers wrapped spirally on the periphery.
