ABSTRACT:
An air laid fibrous web product of enhanced absorbency and method of making same having a basis weight of between about 8 to about 50 pounds per ream, and a bulk of at least 0.40 mils per pound per ream, the web product comprising a multiplicity of papermaking fibers distributed randomly in the form of a web, an adhesive material, preferably a latex, essentially permeating said web of randomly distributed fibers and upon curing bonding adjacent fibers, the adhesive material representing between about 15 to about 30% of the basis weight of the web product and between about 0.1 to about 5.0 by weight of a hydrophile, said hydrophile substantially coating the bonded fibers. The hydrophile is applied to the web as an aqueous solution downstream of the bonding station, either in an immersion or spray treating step.
