<p>PROBLEM TO BE SOLVED: To provide a regenerable absorber and to use this absorber to provide a sanitary article such as a regenerable paper diaper or the like, various mats, various sheets for a person or an animal and a packaging material. SOLUTION: The absorber is equipped with a first water absorbable paper layer, a second water absorbable paper layer and the water absorbable material layer containing a thermal polymeric gel or pulp to be formed between the first and second water absorbable paper layers or a water absorbable material layer containing the thermal polymeric gel, pulp and a water absorbable layer to be formed between the first and second water absorbable paper layers. The first water absorbable paper layer, the water absorbable material layer and the second water absorbable paper layer are combined to be integrally formed. Since the first and second water absorbable paper layers and the water absorbable material layer comprising the compound of pulp, the thermal polymeric gel and the water absorbable resin are provided, the absorber after used is heated to a temperature higher than the temperature- sensitive point of the thermal polymeric gel to be easily dehydrated by the water absorbability of pulp. Further, the absorber after used is immersed in water to be allowed to absorb water to remove soluble components and this absorber having absorbed water is heated and dried at the temperature higher than the temperature-sensitive point to be reused.</p> |
