Description

A kind of high-strength vortex spinning yarn and production method thereof

technical field

The invention relates to the technical field of vortex spinning yarns, in particular to a high-strength vortex spinning yarn and a production method thereof.

Background technique

Vortex spinning is a spinning equipment suitable for spinning pure cotton developed by Japanese murata company on the basis of air-jet spinning. The spinning principle of vortex spinning is as follows: the drawn sliver is supplied to the drafting device, and the fiber bundles drawn by the roller drafting device are output from the front roller jaws, and under the action of the axial air flow at the entrance of the spinning nozzle, the fiber bundles follow the spiral direction. The shaped fiber guide channel enters the spinning nozzle. A needle-shaped twist resistance member is arranged at the outlet of the spiral fiber guiding channel, and the fiber bundle is bent at the needle part, so that the fiber bundle is kept in a state without adding twist and is introduced into the vortex chamber. The front end of the fiber bundle is pulled into the yarn channel in the spindle by the dragging action of the formed yarn, and twisted into the newly formed yarn to become the yarn core. The trailing end of the fiber remains in the fiber guiding channel while being gripped by the front roller jaws. When the tail end of the fiber is no longer held by the front roller jaws, it is centrifugally affected by the air vortex in the spinning nozzle, and is no longer kept in the fiber guide channel, but is radially dissipated by the rotating airflow at the entrance of the spindle Driven by the air vortex, it falls on the tapered surface of the front end of the spindle, and at the same time rotates with the air vortex, wraps around the subsequent yarn, and is output through the yarn channel inside the spindle. The resulting yarn consists of a core of approximately parallel untwisted fibers and a helically wrapped fiber around the periphery.
