ABSORBENTS AND PROCESS FOR PRODUCING THE SAME, ABSORBABLE CONSTRUCTS AND ABSORBABLE ARTICLES |
摘要 |
<p>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. <IMAGE></p> |
