Process for preparation of discontinuous filament bundles and sharp-ended filaments

摘要

A process for the preparation of discontinuous filament bundles, which comprises applying a drawing force and/or a shearing force to a bundle of continuous filaments while or immediately after contacting the bundle of continuous filaments with a medium maintained at a temperature lower than -5 DEG C. to cut the respective single filaments constituting the bundle. The individual filaments of the resultant bundle may have on at least one terminal thereof a sharp end cut obliquely and an inclination angle alpha of the cut top end to the filament axis of less than 70 DEG .
