ABSTRACT:
An apertured non-woven fabric comprising a web of thermoplastic fibers is described. The fabric is formed with a multiplicity of fused patterned regions and adjacent substantially non-fused regions, there being apertures formed within a plurality of the fused patterned regions but not within the adjacent regions. The fabric is produced by heat embossing a non-woven web of thermoplastic fibers at a temperature above the softening point of the fibers whereby the regions of the web compressed by the projections of the embossing means become fused, and immediately thereafter drafting the embossed web so that apertures are formed in the fused patterned regions.
