ABSTRACT:
A method for drawing a synthetic thread having a fibril bundle delivers the thread as a ribbon of substantially parallel fibrils through a drawing bath to effect a hydrodynamic braking of the filaments and simultaneous drawing of the filaments. A ceramic pin is used to form the fibrils into parallel relation and substantially in one plane. A second ceramic pin may also be used as a mechanical brake to add to the hydrodynamic braking action by the liquid in the drawing bath. The base and cover of the drawing device are provided with channels to define the flow path for the bath liquid as well as inlet and outlet channels for the liquid. Suction nozzles or air nozzles may be provided at the inlet and outlet ends of the flow paths to remove excess liquid from the fibrils.
