A process of manufacturing a stretch composite is disclosed. The process comprises providing a polyolefin based substrate, providing a letterpress adhesive application system comprising a pattern roll and an applicator roll, and depositing a molten, non-adhesive, elastomeric composition onto the applicator roll. The process further comprises transferring only a portion of the elastomeric composition that is on the applicator roll, from the applicator roll to the pattern roll, by contacting the pattern roll with the elastomeric composition that is on the applicator roll, and transferring substantially all of the elastomeric composition from the pattern roll to the substrate, by contacting the substrate with the elastomeric composition that is on the pattern roll, without damaging the substrate.

Letterpress application of elastomeric compositions

A disposable absorbent article is claimed that comprised a backsheet and an absorbent core and a core coversheet or topsheet, that in use faces the wearer, and one or more cuffs (), comprising one or more longitudinally extending elastic laminate portion(s) (), formed by at least an elastic material () attached to a supporting sheet () of said cuff (), said laminate portion(s) () comprising in at least relaxed and partially contracted state a body-facing surface with a multitude of wrinkles, and whereby said elastic laminate portion () has an absolute contracted length Land a fully stretched absolute length L,

Absorbent articles with comfortable elasticated laminates

The invention provides a process to deliver an elastomeric composition to a substrate. The elastomeric composition is cooled. The cooling also results in substantially complete transfer of the elastomeric composition from the pattern roll to the substrate with a resulting reduction in elastomer degradation.

A disposable waste-containment garment such as a disposable diaper, an external incontinent protection garment for adults (e.g. adult incontinent briefs), an external catamenial, or a disposable liner for either a disposable diaper or an incontinent brief. The garment, which may be elasticized by, for example, having elasticized leg cuffs and waistbands, comprises an absorbent core comprising substantially unbonded fibers disposed between a liquid permeable lamina and a liquid impermeable backsheet, and the liquid permeable lamina and the absorbent core are bonded together in face to face relation with an open pattern of adhesive: preferably a fine scale reticulated network of filaments of pressure sensitive hot melt adhesive having a weight of from about one-half (1/2) milligram to about three (3) milligrams per square inch (from about 0.8 to about 4.7 grams per square meter) but, more preferably, from about one-and-three-tenths (1.3) milligrams to about two-and-three-tenths (2.3) milligrams per square inch (from about 2.0 to about 3.6 grams per square meter) and, most preferably, about two (2) milligrams per square inch (about 3.1 grams per square meter). In a preferred embodiment of such a garment, the liquid permeable lamina is a portion of a wet-strength-tissue envelope in which the absorbent core is disposed and secured; and the core further comprises elements of highly liquid absorbent matter which elements may be fibrous or particulate or the like in form. Additionally, such garments may further comprise additional laminae which may also be adhesively secured together or to the above enumerated elements: preferably in the manner in which the lamina described above is adhesively secured to the absorbent core.
