Abstract

Procedure for the manufacture of discontinuous fibrils by sudden expansion of a biphasic mixture containing molten polymer and solvent and which is under high pressure and temperature so that the solvent is instantly vaporized and the polymer solidifies, characterized in that the liquid biphasic mixture it is expanded by high speed ejection through a hole so that an ejection cone is formed and into which the ejection cone is sprayed.
