Unitary storage layer for disposable absorbent articles
A unitary storage layer for an absorbent article, being formed by at least two sub-layers in which a first outermost sub-layer forms said first surface and includes cellulose pulp fibers and cross linked cellulose fibers and includes less than 5% of SAP by weight of the sub-layer, and a second sub layer which includes cellulose pulp fibers and SAP and is immediately adjacent to said first sub-layer.
ABSORBER AND ABSORBENT ARTICLE
An absorbent member (1) according to the present invention includes: an absorbent sheet (2) that includes a substrate layer (20) and an absorbent layer (21) that includes water-absorbent polymers (P1) that are fixed to one side of the substrate layer (20); and an entangled fiber layer (3). The water-absorbent polymers (P1) of the absorbent layer (21) and the entangled fiber layer (3) are adjacent to each other. The water-absorbent polymers (P1) of the absorbent layer (21) are preferably fixed to one side of the substrate layer (20) using a hot melt adhesive. The absorbent member (1) configured as described above has excellent absorbency and shape stability while being thin.
Multi-layered absorbent article
A thin absorbent composite is provided wherein a nonwoven support sheet is hydro-entangled with a carded fiber web to provide a nonwoven substrate. The nonwoven substrate is coated with an absorbent layer comprising microfibrillated cellulose-coated superabsorbent polymer particles. A cover layer is placed above the absorbent layer to provide the absorbent composite. A process for manufacturing the absorbent composite and an absorbent article containing the absorbent composite are also provided.
Cotendered nonwoven/pulp fabric and method for making the same
The present invention is directed to a nonwoven fabric made from a composite of nonwoven and pulp where the nonwoven has a high loft derived from a heat set three-dimensional relief structure and/or hydroengorged fiber structure. A nonwoven web is hydraulically treated to create a hydroengorged material having an increased loft. Alternatively a nonwoven web is treated to have a heat set three-dimensional relief structure. The treated web is then hydroentangled with pulp to form a cotendered nonwoven/pulp composite fabric.
COTENDERED NONWOVEN/PULP FABRIC AND METHOD FOR MAKING THE SAME
The present invention is directed to a nonwoven fabric made from a composite of nonwoven and pulp where the nonwoven has a high loft derived from a heat set three-dimensional relief structure and/or hydroengorged fiber structure. A nonwoven web is hydraulically treated to create a hydroengorged material having an increased loft. Alternatively a nonwoven web is treated to have a heat set three-dimensional relief structure. The treated web is then hydroentangled with pulp to form a cotendered nonwoven/pulp composite fabric.
UNITARY STORAGE LAYER FOR DISPOSABLE ABSORBENT ARTICLES
The present invention relates to a unitary storage layer for an absorbent article, being formed by at least two sub-layers wherein a first outermost sub-layer forming said first surface and comprises cellulose pulp fibers and cross linked cellulose fibers and comprises less than 5% of SAP by weight of the sub-layer, and a second sub layer which comprises cellulose pulp fibers and SAP and is immediately adjacent to said first sub-layer.
