Water absorbent composition and material

Water absorbent material comprising:

• (A) water absorbing polymer particles which are capable of absorbing 35 to 100 times of physiological saline solution based on their own weight, at least 90% of the polymer particles having a size of 0.1 to 0.9 mm,
• (B) powders of at least one resin selected from the group consisting of polyolefin modified by carboxylic acid, olefin-acrylic acid copolymer and copolymer of olefin-maleic anhydride, said resin having a melting point of about 70.degree.-100.degree. C., which remains undissolved and unhydrolyzed after being in contact with water for 24 hours, the powders (B) having a particle size not greater than 300 .mu.m and being present in an amount of 0.5-30 parts by weight per 100 parts by weight of the polymer particles (A) and
• (C) at least one fibrous material having a fiber length in the range of 1-200 mm and 0.1 to 100 denier, selected from the group consisting of sheath and core biocomponent fiber, eccentric core-sheath bicomponent fiber, side-by-side bicomponent fiber and cellulose fiber, in which the melting point of the lowest melting component of the biocomponent fiber is 50.degree.-180.degree. C., the weight ratio of the polymer particles to the fibrous material ranging from 20:80 to 95:5;
• wherein the polymer particles (A) adhere to the fibrous material (C) through the resin (B) as a result of heat treatment at temperatures higher than the melting point of the resin powder (B).
