How to use polyester filament and cotton fiber to spin core-spun yarn?

Apr 06,2023

The roving machine of the spinning machine is equipped with polyester filament bobbins, and the lower row is equipped with roving. No lateral device of the spinning machine is used. Polyester filament is fed from above the roller, combined with the stretched cotton sliver, and then twisted and spun into a core-spun yarn. In this method, due to the axial unwinding of the filament, it is inevitable that the filament will move in a circular direction along the tube during the unwinding process. When passing through the guide rod, it will inevitably swing left and right, and the swing amplitude will change with the change of the unwinding diameter. To solve this problem, a guide hook can be installed on the top of the roller to fix the filament in the middle of the strip, which is not affected by objective conditions, maintains synchronization, and has a good coating effect.
