Abstract
A sheet-like article suitable, for example, for wiping hard surfaces, comprises two sheets of nonwoven fabric or the like having sandwiched betweem them a solid core material which may be a highly porous, optionally liquid-containing, polymer. The two outer sheets are bonded to each other, without involving the core material, by means of a plurality of small, spaced bonding points, for example, spot-welds. Preferably the core material is in continuous sheet form and is perforated to accommodate the bonding points.
