Abstract:
A water decomposable fibrous sheet comprising fibers containing fibrillated rayon, the fibrillated rayon having primary fibers of a predetermined fiber length and microfibers extending from the primary fibers;the fibrillated rayon including a first fibrillated rayon having a degree of beating of at most 700 cc, of which the length of the primary fibers falls between 1.8 mm and 4.0 mm at the peak of its self weighted, average fiber length distribution profile curve, and a second fibrillated rayon having a degree of beating of at most 700 cc, of which the length of the primary fibers falls between 4.5 mm and 10.0 mm at the peak of its self weighted, average fiber length distribution profile curve, and the microfibers extending from the first fibrillated rayon and the second fibrillated rayon being entangled with and/or hydrogen bonded to at least either of other microfibers and other fibers.
