Abstract
Disclosed herein is a urine absorbing and holding material, which comprises a homopolymer of at least one monomer selected from specific N-alkyl- or N-alkylene-substituted acrylamides and methacrylamides, a copolymer of two or more of the acrylamides and methacrylamides, a copolymer of said at least one monomer with one or more monomers other the the acrylamides and methacrylamides and copolymerizable therewith, and being a water-insolubilized product. By combining the urine absorbing and holding material in the form of powder, granules, flakes, fibers or a film with a fibrous material in the form of a woven fabric, non-woven fabric or a flocculent material, a useful urea absorbing and holding composite material is obtained in the form of a pad, diaper or drawers.
