  • Patent number: 6562016
    Abstract: A paper diaper using an water-absorbing polymer is superior in absorbency/water-retaining performance to a cloth diaper, but it has the drawback that it generates garbage and is expensive. An water-absorbing pad is formed by allowing an water-absorbing polymer which is dispersed, dissolved or melted or the crosslinks of which are broken in an electrolytic aqueous solution to be retained by a water soluble material. An water-absorbing product is produced by interposing the water-absorbing pad thus formed between sheets of cloth or other materials. The water-absorbing pad secured within the product is dissolved when washed with an electrolytic aqueous solution, and the product itself is reusable.
