Abstract

A process for obtaining water-dispersable polyolefin fibers endowed with a high degree of cohesion consists in maintaining the fibers in contact with a stable emulsion formed by a water solution of polyvinyl alcohol and a poor solvent for the polyolefin, under stirring in turbulence conditions, at a temperature lower than the boiling temperature of the emulsion.
