Abstract
A process for the manufacture of fibrids of thermoplastics materials by extruding molten thermoplastics through dies and breaking up the extrudate into fibers by means of a liquid medium causing shear stresses within a small volume, to which end the extrudate is passed to a zone of high energy dissipation so that it is completely divided up into fibers of the desired size in a single pass.
