Abstract
Disclosed is a water-absorbing composite body comprising a tape-shaped laminate having at least one layer of a high-melting-point synthetic resin and at least one layer of a low-melting-point synthetic resin, in which at least a part of the low-melting-point synthetic resin layer is exposed to the surface, a split fiber obtained by splitting this tape-shaped laminate or a composite fibrous body having a laminate structure as described above, and a powdery polymeric water absorber fusion-bonded to the outer surface of the low-melting-point synthetic resin layer exposed to the surface. This water-absorbing composite body has a high water-absorbing capacity and retains a good mechanical strength.
