Abstract: An economical, reusable primary two mechanism fastener system useable with disposable absorbent products is provided. The fastening system comprises a first and second fastening portion. The first fastener portion comprises a hook fastening material and a first cohesive portion. The second fastening portion comprises a nonwoven fibrous portion engageable with the hook fastening material and a second cohesive portion engageable with the first cohesive portion. The hook fastening material has base and hook surface areas. Various embodiments of the first fastening portion include the first cohesive portion being coated on a portion of the hook fastening material. For example, the cohesive may be coated on the base surface area alone, the hook surface area alone or a portion of both the hook and surface area portions.

Abstract: An elastomeric, hot-melt adhesive foam is disclosed. The adhesive foam preferably comprises an elastomeric, hot-melt adhesive material formed from(a) about 15% to about 60%, by weight of the adhesive material, of an A-B-A block copolymer, in which the A block is derived from styrene and the B block is derived from butadiene or isoprene.(b) about 30% to about 70%, by weight of the adhesive material, of an aromatic modified hydrocarbon resin which associates with both the B block and A blocks of the A-B-A block copolymer, and(c) 0 to about 30%, by weight of the adhesive material, of a processing oil.The proportions of the components (a), (b), and (c) are selected such that the elastomeric, hot-melt adhesive material has a viscosity of less than about 200,000 centipoise at 325.degree. F. and an elastomeric retention value of at least 75%.

Abstract: A method of making an elastomeric, hot-melt adhesive foam is disclosed. The method involves melting an adhesive material, mixing a gas with the adhesive material under pressure to form a solution of the gas in the adhesive material, reducing the pressure to cause evolution and/or expansion of the gas to form a foam, and stabilizing the foam by causing the adhesive material to solidify. The relatively low melt-viscosity of the adhesive material which is used to form the foam provides desirable processing times and the ability to form foams having desired physical properties, e.g., caliper and cell structure.

Abstract: The present invention is directed to a mechanical fastening system for use with disposable absorbent products. More particularly, a reinforced landing surface is disclosed for securing a hook-type mechanical fastener thereto. The reinforced landing surface includes a fibrous non-woven layer and a scrim-like web that is attached in a composite arrangement to the fibrous non-woven layer. The mechanical fasteners include a plurality of hooks, such as those used in a hook and loop type fastener which extend through the scrim-like web and penetrate the non-woven fibrous layer and become intertwined therewith. Depending upon the fastening requirements, the pattern of the scrim-like web may be repetitive, variable, continuous or discrete.

Abstract: A fluid pervious web suitable for use as a topsheet on an absorbent article is disclosed. The topsheet includes a fibrous and apertured, three-dimensional, macroscopically expanded, plastic web. The fibrous and apertured, three-dimensional, macroscopically expanded, plastic web permits bodily fluids to penetrate while providing an improved, less plastic-like feel and visual aesthetics.
