Description of the Related Art Conventionally, a water-disintegrating sheet containing a sterilizing and disinfecting component and easily decomposed in water has been commercially available as a toilet cleaning article, and can be flushed to the toilet for disposal after use. Popular as a disposable product. Toilet cleaning sheets are required to have sufficient wet strength to withstand wiping by wiping, and water disintegration that does not cause clogging of the drainage pipe even if flushed to the toilet for disposal after use. A water-disintegratable sheet having a good balance between wet strength and wet strength is being researched and developed.

壊性シートの水崩壊性が劣化するという問題があった。In order to improve the wet strength of the water-disintegratable sheet, it has been proposed to use a water-soluble resin as a binder. For example, JP-A-42-7957 discloses that polyvinyl alcohol is gelled with a water-soluble salt to improve the strength. However, the solubility of polyvinyl alcohol in water is as described in “Adhesion”, Vol. 34, No. 11, page 519 (1990),
It is known to be related to its crystallinity, and its crystal part is formed by hydrogen bonds. for that reason,
In polyvinyl alcohol, the hydrogen bond of polyvinyl alcohol itself gradually progresses in the electrolyte aqueous solution, the crystallinity increases and the solubility in water deteriorates, and the water disintegrability of the water disintegratable sheet deteriorates due to long-term storage. There was a problem.

However, although the water disintegration property is good, it is difficult to obtain sufficient wet strength. In addition, although it has been proposed to use a natural water-soluble resin as a binder,
It has been difficult to obtain a water-disintegratable sheet having a well-balanced wet strength and water-disintegratability.

Furthermore, the present invention comprises applying a binder of 1 to 20 g / m 2 to a water-disintegratable sheet material made of pulp, natural fibers or synthetic fibers, and then impregnating it with 3 to 30% by weight of an electrolyte solution.

したシートの水崩壊性が不良となる。BEST MODE FOR CARRYING OUT THE INVENTION The polyvinyl alcohol having a saponification degree of 95 to 80 mol% which constitutes the binder for a water-disintegratable sheet of the present invention is gelated by salting out with an electrolyte to increase the wet strength of the water-disintegratable sheet. If the degree of saponification is less than 80 mol%, the effect of salting out is low and sufficient wet strength cannot be obtained. On the other hand, when the saponification degree of polyvinyl alcohol is out of the above range, the solubility in cold water is lowered, and the water-disintegratability of the sheet coated with this becomes poor.

阻害が湿潤強度の低下に直接つながらない。The water-insoluble powder which constitutes the binder for a water-disintegratable sheet of the present invention is added for the purpose of preventing deterioration of water-disintegratability due to long-term storage of polyvinyl alcohol. The reason why the water-insoluble powder prevents deterioration of the water-disintegrating property of polyvinyl alcohol is considered to be that the water-insoluble powder has an effect of increasing the crystallinity of polyvinyl alcohol, that is, inhibiting the progress of hydrogen bonding. On the other hand, as for the wet strength, if the polyvinyl alcohol binding between the short fibers of the fibers to be the water-disintegratable sheet material is not dissolved in water, the strength is maintained.
