摘要:
In an absorbent article, such as a diaper or incontinence briefs, an elastic member comprising a net-like elastic substrate to which fibers are pre-bonded provides for a breathable elastic for use as a side- a waist- or leg elastic. The fibers that are bonded to the net-like substrate, for instance by hydro-entangling, ensure a soft and comfortable contact with the wearer's skin. In the side panels of the absorbent article, the elastic members have a large freedom of stretch without buckling taking place, thus reducing chances of leakage. When the elastic member is located between the topsheet and the backsheet, a strong connection of topsheet to backsheet is established using a relatively small amount of adhesive. When the topsheet is physically deformed to impart stretchability, the fibers of the elastic member form a soft and resilient layer and prevent direct contact of the elastic member and the user's skin in case of thinning of the topsheet.

Absorbent article such as disposable diapers, incontinent briefs, diaper holders and the like, that have a unique elastic waist feature that improve the dynamic fit of the elasticized waistband as well as the containment characteristics of the absorbent article. The elastic waist feature comprises an "expansive tummy panel" that is capable of expanding well-beyond the dimensions of the absorbent article set by the primary fastening system (and the original dimensions of the end edge) so as to accommodate wearers, especially large infants, with large expansile waists so as to reduce the sagging/slipping of the absorbent article. The extension forces of the elasticized waistband are lower than the extension forces of the elasticized side panels so as to accommodate such expansion. In preferred embodiments of the elastic waist feature, the elasticized waistband is formed from a stretch laminate.

A method for imparting varying degrees of elasticity in different areas of a resilient material for disposable absorbent articles includes providing an elastic material and removing material from areas of the elastic material which are to be given a lesser degree of resilience than remaining areas. At the same time attached material parts are left in those areas of the elastic material from which material has been removed.

A sanitary napkin wrapper and adhesive tab construction for such a wrapper are disclosed. The adhesive tab can, in a preferred embodiment, be applied to the package formed by the wrapper contemporaneously with its own landing member to form a complete fastening system. The sanitary napkin wrapper can also be provided with a flap or pouch in several variations for securing the used sanitary napkin for disposal.

A simplified process is disclosed for making form-fitting undergarments that may include structures for absorbing and containing body exudates. The garments are cut and seamed into rectangular or trapezoidal shapes from nonwoven elastic sheet that has parallel rows of elastic strands and specific stretch and simultaneous contraction characteristics. The finished garment when stretched in the waist direction simultaneously contracts in the direction perpendicular thereto by at least 20%.
摘要:
An absorbent article, such as a sanitary napkin, having flaps that have inwardly-folded pleats that provide zones of differential extensibility for relieving the stresses that develop in the flaps when the flaps are folded down along the edges of crotch of the wearer's undergarments is provided.

Disposable training pants improved for effectively making babies wearing the training pants aware of their own excretions. There are provided on a topsheet of the pants a moistness holding sheet 11 having floating zones 11a serving as moistness sensor means.
摘要:
The stretchable composite comprises a liquid-pervious layer, liquid-impervious layer, an absorbent layer, and a stretchable layer. The stretchable layer is stretch-bonded to the other layers and, upon relaxing the stretched layer, a plurality of rugosities are formed in the liquid-pervious layer, liquid-impervious layer, and absorbent layer. A method is provided for making the composite.

A multilayer film comprises a elastomeric core layer and at least one thermoplastic skin layer having a microundulating surface configuration providing the film with a low gloss.
摘要:
The stretchable undergarment comprises a liquid-previous bodyside layer, liquid-impervious outer layer, an absorbent layer, and a stretchable layer. The stretchable layer is stretch-bonded to the other layers and, upon relaxing the stretchable layer forms a plurality of rugosities in the bodyside layer, outer layer, and absorbent medium. The bonded layers are of a generally trapezoidal shape and have a front end portion that diverges toward a rear end portion, wherein the front end portion is from about 20% to about 90% of the width of the rear end portion, and the rear end portion is about 20% to about 60% of the length of the bonded layers.
