Abstract
Process for the preparation of high and linear propylene polymer fibers, characterized in that it comprises extruding a homogeneous solution of a high crystallizable and linear polymer of propylene in a solvent thereof through a nozzle, volatilizing the solvent of the filament thus produced and orienting the filament by stretching it to an elevated temperature.
