Spinning Methods And Devices For Manufacturing Artificial Fibers

Abstract
Process for the spinning by melting of synthetic linear polymers, characterized by the extrusion of the molten polymer through a spinneret, so that a stream or polymer flow is formed whose cross section widens, at each of its ends from 2 to 5 times its narrowest width, the length of said section being at least 5 times its narrowest width; then rapidly cooling said stream of molten polymer to form a modified filament, from whose cross section the widened portions of the ends have substantially disappeared; finally the filament is stretched.
