BODILY FLUID ABSORBENT MATRIX AND METHOD FOR MANUFACTURING THE SAME

摘要

A bodily fluid absorbent matrix adapted to restrict a wet feeling against the wearer's skin after the absorbent matrix in a bodily fluid absorbent wearing article having absorbed bodily fluids and a method for manufacturing the absorbent matrix. A bodily fluid absorbent wearing article has an absorbent matrix formed of aggregate of bodily fluid absorbent material between a liquid-permeable first sheet and a liquid-impermeable second sheet. The member includes hydrophilic fibers as the bodily fluid absorbent material. Density of the absorbent matrix changes so as to increase from the first sheet toward the second sheet in thickness direction of the absorbent matrix. A planar orientation index of the hydrophilic fibers also changes so as to increase in the thickness direction of the absorbent matrix.

1. A bodily fluid absorbent matrix including an aggregate of bodily fluid absorbent material interposed between a liquid-permeable first sheet lying on the skin-facing side in a bodily fluid absorbent wearing article and a liquid-permeable or liquid-impermeable second sheet lying on a garment-facing side opposite to the skin-facing side, wherein:
the absorbent matrix includes hydrophilic fibers serving as the bodily fluid absorbent material; the absorbent matrix has a density gradient so as to increase from the first sheet toward the second sheet in a thickness direction of the absorbent matrix; and a planar orientation index of the hydrophilic fibers increases in the thickness direction.
