Abstract
A process of melt spinning a fibre-forming polymer particularly polyethylene terephthalate or poly-hexamethylene adipamide at a minimum wind up speed of 1000 meters per minute in which there is added to the fibre-forming polymer before spinning a small proportion of a polymer capable of forming an anisotropic melt in the temperature range at which the fibre-forming polymer may be melt spun whereby in the process there is suppression of wind up speed compared with the process carried out in the absence of the added polymer.
