PROBLEM TO BE SOLVED: To obtain a water-disintegrable fiber sheet and provided a method for simply producing the water-disintegrable fiber sheet. ;SOLUTION: The water-disintegrable fiber sheet containing a fiber comprising hardwood pulp and a fiber comprising needle-leaved tree pulp whose average fiber length is longer than that of the hardwood pulp and a water-insoluble or water-swelling binder, is produced. The resultant fiber sheet has good water- disintegrability and a strength capable of withstanding the use. Further, the producing method is simple, because a fiber sheet excellent in water- disintegrability and strength without using the water-soluble binder can be obtained.;COPYRIGHT: (C)1999,JPO
