Body Fluid Absorbent Panel
Patent #: 6,706,943
Inventor(s): Kazuaki Onishi, Masashi Nakashita
Company: Uni-Charm Corporation
A body fluid absorbent panel, comprising of a first sheet which is liquid-pervious and a second sheet has been patented. This structure has a core disposed between the first and second sheets that comprises component fibers defining a three dimensional network structure and absorbent polymer particles distributed in the network structure. The particles are contained within the network structure by being held between adjacent component fibers or are bonded to the component fibers. These component fibers comprise the previous fibers that have a lower melting point and second fiber of a higher melting point. The network structure has spots at which the first fibers are fused together, and second spots at which the first fibers are fused to the second fibers. Bonds between the first fibers at the first spots are stronger than bonds between the first and second fibers at the second spots.
