Abstract
A nonwoven texturized fabric is produced by embossing a molten film of a polymer blend of high density polyethylene and polystyrene with hexagonal shaped bosses, biaxially stretching the thus embossed film to produce an openwork net and then texturizing the net with special texturizing rollers to flatten and deform some of the bosses and bend some of the bands at an angle to the plane of the fabric to produce an essentially irregular pattern of bosses connected by bands.
