Absorbent Article Having Superabsorbent Pockets in a Non-Absorbent Carrier Layer

적은 벌크를 가진 비교적 경량의 흡수성 제품은 액체 투과성 상부층, 내부 서지층 및 실질적으로 액체 불투과성인 외부 커버를 포함한다. 서지층 및 외부 커버 재료 중 하나 이상 내에는 복수의 포켓이 형성되어 있다. 그 포켓은 초흡수성 재료를 함유한다. 포켓을 함유하는 서지층 또는 외부 커버 재료는 흡수층으로서 기능함으로써 서지층과 외부 커버 사이에 별개의 (종종 부피가 큰) 흡수층을 필요로 하지 않는다. Relatively light absorbent articles with low bulk include a liquid permeable top layer, an inner surge layer and a substantially liquid impermeable outer cover. A plurality of pockets are formed in at least one of the surge layer and the outer cover material. The pocket contains a superabsorbent material. The surge layer or outer cover material containing the pocket functions as an absorbing layer, thus eliminating the need for a separate (often bulky) absorbing layer between the surge layer and the outer cover. 초흡수성 포켓, 흡수성 제품, 서지층, 외부 커버 재료 Super Absorbent Pockets, Absorbent Products, Surge Layers, Outer Cover Materials

Matched permeability liner/absorbent structure system for absorbent articles and the like

The present invention is directed to a matched permeability liner/absorbent structure system, suitable for use in absorbent articles, in which the permeability of the bodyside liner is correlated with the permeability of the subjacent layer of the absorbent structure, such as a surge layer. The inventors have observed that by appropriately matching the permeability of the liner material to the permeability of the subjacent layer, liquid intake performance of the liner and subjacent layer materials can exceed liquid intake performance of the subjacent layer material alone. Thus, in accordance with an embodiment of the present invention, the permeability of the bodyside liner is set within a specified range of that of the subjacent layer such that the liner/subjacent layer liquid intake performance is improved. In accordance with another embodiment of the present invention, the permeability of the bodyside liner is matched to or correlated with the permeability of the subjacent layer such that the liner/subjacent layer liquid intake performance is improved at least about 50 percent over the liquid intake performance of the subjacent layer alone. In accordance with yet another embodiment of the present invention, the permeability of the liner material is matched to or correlated with the permeability of the subjacent layer such that liquid intake performance of the liner/subjacent layer combination is improved at least about 65 percent over the liquid intake performance of the subjacent layer alone. As disclosed herein, by properly selecting the permeability of the liner material, as compared with the permeability of the subjacent layer material, the liquid intake rate of the liner material not only does not limit or inhibit liquid intake into the subjacent layer and underlying components of the absorbent structure, but provides an unexpected increase in liquid intake performance over that of the subjacent layer alone. The bodyside liner and subjacent layer can ...

Liquid transfer material of a transversely extensible and retractable necked laminate of non-elastic sheet layers

The present invention is directed to a liquid transfer material formed from a necked laminate and a process for making the laminate. The necked laminate is formed from sheet layers of at least one non-elastic neckable material laminated to at least the film non-elastic film defining a longitudinal and transverse dimension. At least the film layer of the laminate is apertured in an area where liquid transfer through the laminate is desired. The entire laminate may also be apertured. The non-apertured part of the laminate remains extensible and retractable in at least one dimension without significantly reducing the breathability and/or liquid barrier properties of the film layer. This laminate extensibility and retractability is the result of striated rugosities in, for instance, the longitudinal dimension of the film layer which enables the necked laminate to have an amount of extensibility and retractability in the transverse dimension. A breathable laminate may be made by first partially stretching the non-elastic film layer, attaching a non-elastic neckable layer to form a laminate and then stretching the laminate to neck the laminate and lengthen the film to its desired fully stretched configuration.

具有快速分配条的吸收用品

本发明公开了一种如带液体分配条的卫生巾之类的吸收物品，这些吸收物品改善了排出液体的分配和虹吸情况，该吸收物品包括一层透液体的上片，一层不透液体的下片，一个吸收液体的衬垫和一条液体分配条。吸收衬垫设置于上片和下片之间，液体分配条位于上片和吸收衬垫之间。上述液体分配条包括由席纹组成的非织造织物片，上述席纹由使纤维和或/高压实的压花花纹之间间隙缩小的高密集度纤维组成，上述席纹的高密集纤维主要地向吸收垫的纵向端取向，使液体沿纵向端散开。大多数压花花纹的高压实部分沿纵向端取向，从而阻挡液体朝横向边缘散开。
