ABSTRACT:
A method of bonding a fluid-porous, fibrous, woven or non-woven web to a substrate and products made thereby. The porous web is overall or pattern coated with an extremely low level of hot-melt adhesive by causing the hot-melt adhesive to be wiped from a controlled thickness hot-melt adhesive source by the individual projecting surface fibers and fiber junctions of the porous web. Hot-melt adhesive globules are formed on the individual projecting surface fibers and fiber junctions which, when the porous web and substrate are passed through a preset clearance nip roll assembly, provide a product wherein the porous web is bonded to the substrate with excellent bond strength, the porous web remaining flexible and completely transparent to fluid transmission.
