Title:
ABSORBENTS AND PROCESS FOR PRODUCING THE SAME, ABSORBABLE CONSTRUCTS AND ABSORBABLE ARTICLES
Document Type and Number:
WIPO Patent Application WO2002005949
Kind Code:
A9
Abstract:
Absorbents comprising an water-absorbable resin and water-insoluble nonporous spherical monoparticles having an average diameter of 1 to 50 nm; a process for producing these absorbent by mixing the spherical monoparticles, which have been solubilized in water, with dry powdery particles of the water-absorbable resin; absorbable constructs composed of the above absorbent with a matrix wherein the amount of the absorbent ranges from 30 to 95% by weight based on the absorbable construct; and absorbable articles provided with the absorbable construct, a liquid-permeable sheet and an air-permeable back sheet. These absorbents, absorbable constructs and absorbable articles are excellent in the diffusion/absorption speed and absorption amount of a liquid within the resin even in case of absorbing a liquid containing water-insoluble or hardly water-soluble matters such as menstrual blood or feces.
