Abstract:
A body fluid absorbent panel, comprising:a first sheet which is liquid-pervious and a second sheet; and a core disposed between said first and second sheets, said core comprising component fibers defining a three dimensional network structure and absorbent polymer particles distributed in said network structure; wherein: said polymer particles are contained within said network structure by being held between adjacent said component fibers or bonded to said component fibers; said component fibers comprise first fibers of a lower melting point and second fibers of a higher melting point; said network structure has first spots at which said first fibers are fused together, and second spots at which said first fibers are fused to said second fibers; and bonds between said first fibers at said first spots are stronger than bonds between said first and second fibers at said second spots.
