Abstract

A spinning-drawing-winding device for industrial polylactic-acid fiber includes a double-surface oiling mechanism, a filament shearing-suctioning device, a pre-interlacer and a splitting filament roller disposed in sequence according to a production process; a drawing-winding device cooperates with a spinning device, a tow passing from the spinning device through the double-surface oiling mechanism, the filament shearing-suctioning device, and the pre-interlacer in sequence until the tow is conveyed to the splitting filament roller; the drawing-winding device and the spinning device are configured as a parallel configuration, so that the tow between the spinning device and the splitting filament roller are arranged in a vertical direction and is tangential to the splitting filament roller, and therefore the tow is without deflection, thereby avoiding damaging the tow due to a friction caused by a higher deflection.
