Abstract
Official abstract text for this publication.
The present invention provides a bodily fluid-absorbent structure improved so as to facilitate bodily fluids to disperse in a thickness direction of the structure. Core material of a bodily fluid-absorbent structure is formed of an aggregation of fluff wood pulp fibers. The aggregation has a basis mass in a range of 150 to 500 g/m 2 and a specific volume in a range of 3 to 20 cc/g. In the aggregation, a relationship between horizontal orientation index I H and specific volume VSP of fluff wood pulp fibers is represented by a formula as follows: I H is less than or equal to −0.099VSP+2.4.
First claim
Opening claim text (preview).
The invention claimed is: 1. A bodily fluid-absorbent structure, comprising liquid-absorbent material formed of an aggregation of fluff wood pulp fibers and having an inner surface and an outer surface, a liquid-pervious sheet covering said inner surface, and a liquid-pervious or liquid-impervious sheet covering said outer surface, wherein said aggregation has a basis mass in a range of 150 to 500g/m 2 and a specific volume in a range of 3 to 20 cc/g; a relationship betw…
