Embodiment Construction

[0146]Film Preparation-Films containing varying amounts of elastomeric polymers, modified resins, and mineral oil as shown in Table 1 were used to prepare selected stretch laminates. Blending can be achieved by extruding the elastomer (sample film 1) or by solvent casting the mixture and pressing it into a film (sample films 2, 3, 4) on a Carver hot press. The amount of each component is expressed as a weight percentage of the elastomer composition. The examples in Table 1 contain styrene-isoprene-styrene (S-I-S) triblock copolymers under the trade name Vector  4211 is commercially available from Dexco Polymers L.P., Houston, TX. In sample films 2 to 4, the elastomer composition includes white mineral oil, under the trade name Bristol  50T is commercially available from Crompton Corporation, Petrolia, PA. The sample film 2 included a modified resin in the form of an alicyclic hydrocarbon resin, which was purchased from Arakawa Chemical Inc., Chicago, IL under the trade name Arko...

Abstract

Absorbent articles may comprise a topsheet, a backsheet joined to the topsheet, an absorbent core disposed between the topsheet and the backsheet; and one or more article elements. The article elements are selected from the group consisting of anal cuffs, elasticized topsheets, fastening systems, leg cuffs, waist elastic components, side panels, ear panels, and combinations thereof. The article element may comprise a slow recovery stretch laminate. The stretch laminate exhibits an unloading force of about 0.16 N / (g / m) or greater at 37°C and an initial strain percentage of about 10% or greater after recovery at 22°C for 15 seconds.

Description

Invention field [0001] The present invention relates to absorbent articles including slow recovery stretch laminate materials, such as diapers, training pants, adult incontinence products, feminine hygiene products, and the like. Background of the invention [0002] Stretch laminate materials are well known in the art. It has long been known that in the field of disposable absorbent products, people expect to construct absorbent devices with stretch laminate materials, such as disposable diapers with fasteners, pull-on diapers, training pants, sanitary napkins, panty pads, and incontinence briefs. Etc. to improve comfort during exercise and maintain continuous fit. In addition, the stretch laminate material allows the diaper to adapt to wearers of different body sizes. The diaper can have stretch laminate in many of its structures, including waistbands, leg cuffs, side panels, elasticized topsheets, backsheets, ears, and fastening systems. [0003] In application, the diaper can ...
