ABSTRACT:
The present invention relates to a water absorbent composition comprising 100 parts by weight of water absorbing polymer particles and 0.5 to 30 parts of a resin powder having heat adhesion property at 50.degree.-200.degree. C. The present invention also relates to a water absorbing material and water absorbing products using the said water absorbing material comprising the water absorbing polymer particles, a resin having heat adhesion property at 50.degree.-200.degree. C. and fibrous material, wherein the water absorbing polymer particles are adhered to the fibrous material through the resin by heat treatment at temperature exceeding the temperature exhibits heat adhesion property of the resin. The water absorbent composition of the present invention provides excellent adhesion to a fibrous material, while it maintains the water absorbency of the original water absorbing polymer, and is consequently useful as raw material for sanitary goods such as disposable diapers and sanitary napkins etc. The water absorbing material of the present invention has excellent water absorbency, absorbing speed and shape retention property after water absorption. Consequently, it is useful for water absorptive goods such as disposable diapers and sanitary napkins.
