Abstract
An improved fibrous scouring material is disclosed, that material comprising a fibrous band in the form of a three-dimensional lattice of drawn irregular fibers obtained from a plastic bilaminar film, those fibers being helically crimped and self-bonded together at their mutual contact points, the helically crimped fibers exhibiting sharp corner-edges and being interconnected by helically crimped fibrils. The thickness of the fibers is typically between 100 and 200 microns. The process for manufacturing such scouring material is also disclosed, which process includes steps of extruding a bilaminar film, drawing and fibrillating the film, stacking the fibrillated lattice and thermally treating same to induce crimping and self-bonding.
