How To Spin Core Spun Yarn With Polyester Filament And Cotton Fiber

The roving frame of the spinning frame is provided with polyester filament bobbins, and the lower row is provided with roving. There is no traverse of the spinning frame. Polyester filament is fed from the top of the roller, combined with the draft sliver, then twisted and spun into core spun yarn. In this method, because the filament is unwinded axially, it will inevitably move around the bobbin in the unwinding process, and it will inevitably swing left and right when passing through the guide rod, and the swing amplitude will change with the change of unwinding diameter. In order to solve this problem, the guide hook can be installed on the top of the roller to make the filament fixed in the middle of the strip, which is not affected by the objective conditions, keep the synchronization, and the coating effect is good.
