摘要:
Stretch laminate hot melt adhesives and stretch laminates are described. The stretch laminate hot melt adhesives are suitable for adhering elastic materials with inelastic substrates, and allow permanent deformation of the inelastic substrate and extensions and retractions of the elastic materials. The stretch laminate hot melt adhesive is particularly suitable for back ear lamination for disposable absorbent articles.

A generally thin, flexible sanitary napkin capable of handling medium to high menstrual flows which has a central absorbent hump is disclosed. The hump comprises a longitudinally-oriented elongated medial absorbent hump that projects from the body surface of the sanitary napkin. The sanitary napkin preferably has surrounding absorbent regions outboard of the hump with a caliper of less than or equal to about 5 millimeters. The sanitary napkin preferably has a caliper at the point of maximum amplitude of the hump that is greater than twice the caliper of the surrounding regions. The hump preferably has a caliper of at least about 0.15 inch (about 3.5-4 millimeters). The longitudinal central region of the sanitary napkin preferably has a flexure-resistance that is greater than that of the surrounding regions.
摘要:
The present invention relates to absorbent articles such as sanitary napkins worn by women. More particularly, the present invention relates to absorbent articles, such as thin sanitary napkins, that are stretchable, especially in the longitudinal direction.
摘要:
The present invention relates to absorbent articles and non-absorbent articles which comprise at least one improved double-sided soft and elastic material composite. The composites according to the invention may also be breathable. The composites are produced by incrementally stretching a laminate of an elastic layer between two non-elastic cloth-like layers. The non-elastic cloth-like layers tear during stretching such that the elasticity of the laminate after stretching is substantially the same as the elasticity of the film elastic layer.
摘要:
Absorbent articles such as sanitary napkins, panty liners, adult incontinence devices, and the like, which have flaps are disclosed. The absorbent articles have a deformed hinge that is located between at least a portion of the main body portion of the absorbent article and the flaps, and zones of extensibility for relieving the stresses that develop in the flaps when the flaps are folded down and under a wearer's undergarment.
摘要:
A generally thin, flexible sanitary napkin capable of absorbing medium to high menstrual flows, and having a stiffened center is provided. In one embodiment, the sanitary napkin has a longitudinal central region is disposed along the length of at least a portion of the longitudinal centerline, and longitudinal side regions are disposed outboard of the longitudinal central region. The longitudinal central region of the sanitary napkin has a flexure-resistance that is greater than that of the longitudinal side regions. The embodiment of the sanitary napkin described above easily forms around the curvature of the wearer's labia majora by cupping and surrounding the exterior of the labia majora. The longitudinal central region of the sanitary napkin forms the bottom of a cup-like trough under the wearer's labia majora, and the longitudinal side regions are sufficiently flexible that they are able to form the sides of the trough structure.

摘要:
Absorbent articles such as sanitary napkins, panty liners, and incontinence pads are disclosed that have undergarment covering components (or "side wrapping elements") that extend from the main body portion of the absorbent article and automatically fold along the sides of a wearer's panties and provide an alternative to conventional side flaps. The side wrapping elements have at least one zone of extensibility and a region therein that is stiffer and less extensible than the zone of extensibility. The absorbent article preferably comprises at least three regions with different bending moduli to control the location of the absorbent article about which the side wrapping elements will bend.
摘要:
An absorbent article, such as a diaper, sanitary napkin, adult incontinent device which have absorbent cores comprised of blends of different types of fibers are provided. The absorbent articles preferably comprise a liquid pervious topsheet, a liquid impervious backsheet joined to the topsheet, a blended absorbent core positioned between the topsheet and the backsheet, and an acquisition layer. The absorbent core comprises a homogeneous blend of fibers comprising a first group of short, low denier, hydrophilic fibers and a second group of longer, higher denier, moisture insensitive synthetic fibers. The first group of fibers is selected from a group comprising natural fibers, synthetic fibers or cross-linked cellulose fibers. The second group of fibers comprises between about 5 and 90% of said absorbent core, by weight. The absorbent core is compressed to a density of at least about 0.09 g/cm.sup.3 (1.5 g/in..sup.2).
摘要:
The present invention provides absorbent articles, especially sanitary napkins, containing a fluid transport layer. In-use, the transport layer directs menses to a storage layer, thereby minimizing product failure and staining of undergarments. The transport layer can protrude into, or through, a topsheet to provide very aggressive transport of vaginal discharges. Preferably, the transport layer is a layer of fibers having external capillary channels.
