Abstract
Disclosed is an absorbent composite including a web formed from a mixture of fibrous material and particulate absorbent material. The web contains from about 15 to about 30 weight percent water. The described absorbent web is capable of containing relatively large quantities of particulate absorbent materials while maintaining an acceptable degree of flexibility.
Claims20
An absorbent composite, said absorbent composite comprising:
- an absorbent web comprising an airlaid mixture of between 0 and about 45 weight percent, based on total mixture weight, of a fibrous material;
- from about 40 to about 85 weight percent, based on total mixture weight, of a particulate, water-swellable, generally water-insoluble absorbent material capable of absorbing at least about 10 times its own weight in water;
- and from about 15 to about 30 weight percent, based on total mixture weight, of water;
- wherein the fibrous material and absorbent material are bonded such that the absorbent material is substantially contained within said absorbent web.
1 more element
An absorbent composite, said composite comprising:
- an absorbent web formed from an airlaid mixture comprising between 0 and about 45 weight percent, based on total mixture weight, of a cellulosic fibrous material;
- from about 40 to about 85 weight percent, based on total mixture weight, of a particulate, water-swellable, generally water-insoluble absorbent material capable of absorbing at least about 10 times its own weight in water and having a deformation under load of less than about 1.5 millimeters;
- and water in an amount of from about 15 to about 30 weight percent, based on total mixture weight, said water being added to said absorbent composite in the form of a liquid wherein the fibrous material and absorbent material are bonded such that said absorbent web has a shakeout value of less than about 250 milligrams and a Gurley stiffness of less than about 1500 milligrams.
