Estimating the term…
A process is claimed for making a composite sheet useful for an absorbent article, the composite sheet comprising a wrinkled, patterned elasticized region that comprises a patterned first sheet and an elastic material, the first sheet being patterned with troughs, that are typically compacter, i.e. of higher density, prior to attachment to the elastic material. The troughs are attached to the elastic material. The resulting composite sheet has a uniform wrinkle pattern. Also claimed are specific absorbent articles.
A process for making a composite sheet useful for an absorbent article, the composite sheet comprising a wrinkled, patterned elasticized region that comprises a patterned first sheet and an elastic material, comprising the steps of:
An absorbent article comprising a composite sheet comprising a wrinkled, patterned elasticized region, having a longitudinal direction Y and a transverse direction X, and comprising a first sheet and an elastic material, the elastic material extending at least partially in substantially the longitudinal direction Y and providing elasticity in substantially the longitudinal direction Y, wherein the first sheet, or part thereof, comprises in longitudinal direction, and optionally in transverse direction, a pattern of a multitude of troughs and a multitude of crests, the troughs of the first sheet having a higher density than the crests of the first sheet;
An absorbent article comprising a composite sheet that comprises a patterned and wrinkled elasticized region, the elasticized region containing an elastic material and a patterned and wrinkled first sheet, having troughs that are attached or partially attached to the elastic material, and wherein the elasticized region has a residual strain of less than 30%, further wherein the composite sheet comprises a wrinkled second sheet, that may optionally be patterned, and wherein the elastic material is positioned between the first sheet and the second sheet, and wherein the elasticized region has a peel force of at least 2.0 N.
A patterning tool, having an X-direction and Y-direction, the tool being a roll with an X-direction-axis, the tool having raised portions in rows substantially along the X-direction and in columns substantially along the Y-direction, wherein the X-direction height of a raised portion is less than the Y-direction height of the same raised portion and the ratio of the Y-direction height to the X-direction height is at least 3:2, and the X-direction height is from 0.1 mm to 1.0 mm and the Y-direction height is from 0.4 mm to 3 mm.
A tool as in claim 22, which comprises a cooling unit, wherein the tool is cooled by the cooling unit.
