Absorbent Articles

Absorbent articles comprising material webs are disclosed herein. The material webs described herein can provide a bevy of benefits when utilized in the context of absorbent articles, and such material webs can facilitate the manufacturing of absorbent article.

FOAM AND FIBER COMPOSITE

The foam and fiber composite can provide an absorbent article with improved dryness and an improved liquid distribution capability. The foam and fiber composite can be formed from at least two materials. The first material is an open cell foam material and the second material is a fibrous material. A plurality of the fibers forming the fibrous material can be fluid inserted into the open cell foam material thereby forming the foam and fiber composite. In various embodiments, the foam and fiber composite can be incorporated into an absorbent article as a component of an absorbent system located between a topsheet layer and a backsheet layer of the absorbent article.

ABSORBENT PRODUCT COMPRISING FOAM MATERIAL

Absorbent product includes a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core enclosed between the topsheet and the backsheet, wherein the absorbent core includes a liquid inlet foam material located closest to the liquid pervious topsheet and an absorbent fibrous layer located closest to the impervious backsheet. The liquid inlet foam material has in the transversal direction of the absorbent product two edge regions and one central region located between the edge regions. The central region has a plurality of openings formed from a plurality of slits extending in the longitudinal direction of the absorbent product and that openings have been formed from the slits by expanding the continuous liquid inlet foam material in the transversal direction of the product, and that each edge region of the liquid inlet foam material has a width that is at least 5.0 mm and is free from openings.

Absorbent article with klemm gradient and water repellent finishing
09603755 · 2017-03-28 · ·

An absorbent member containing a hydrophobic material subjected to hydrophilic treatment, a plurality of through holes passing through the absorbent member in a thickness direction formed at a portion of the absorbent member in a target region (P). The absorbent member has a layer-stacked structure of a plurality of layers, stacked in the thickness direction. The Klemm water absorption height of a lower layer most proximal to the backsheet is higher than that of an upper layer most proximal to the topsheet. The backsheet contains a moisture permeable film including a plurality of microvoids, and having water repellent portions formed by water repellent finishing, on a portion in the target region (P) of a skin-facing surface of the moisture permeable film. A ratio of the total area of portions on which the water repellent finishing is performed to the area of the target region (P) is from 30% to 60%.

ABSORBENT ARTICLE

An absorbent article includes: a liquid-permeable topsheet; a liquid-impermeable backsheet; an absorbent core disposed between the topsheet and the backsheet; and one or more low liquid permeation portions each of which: has a lower permeability speed of body fluid permeating from a skin side to a non-skin side of the absorbent article than a permeability speed of the body fluid in a surrounding area of the one or more low liquid permeation portions, is disposed on the non-skin side relative to a non-skin surface of the topsheet and on the skin side relative to a non-skin surface of the absorbent core, and is disposed in a central region among three equally divided regions of the absorbent core in a width direction of the absorbent article.
