Basic Principle of Air-Jet Spinning

Basic Principle of Air-Jet Spinning:

Sliver is fed into the machine and is further drawn out to the final count and twist is inserted by means of a rotating vortex of high pressured air. By the action of the vortex, the fiber ends eventually whirl around the spindle tip and are thus twisted around the twist less yarn core and transformed into a twisted yarn surface or cover fibers. This occurs at the spindle tip.

Once inside the spindle tip, the yarn formation process is finished, and the yarn can be taken off and wound onto a package.
