<p>Synthetic thread is prepd. from a prim. film free from molecular orientation, by extrusion, blowing and multiple simultaneous longitudinal shearing. To increase efficiency, after subsequent heating for drawing to size, the threads are then carried to the machine in the flexible state. - The inherent ductility of the thread reaching the rectilinear or circular weaving machine increases the weave quality.</p> |
