Abstract
Surface wetting of scored textile film strands facilitates fibrillation thereof. Liquid water of inert aqueous solution is applied by various means in the form of droplets or a thin surface layer to such strands, which then are compressed laterally and longitudinally to fibrillate and crimp them, as by stuffer crimping, in a continuous process optionally including predrawing the strands to increased length.
