摘要： Provided is a multi-layered water-decomposable fibrous sheet with a plurality of layers each having a different fibrous constitution being integrated, including a top layer on a top surface and a back layer on a back surface. The top layer includes fibrillated rayon of at least 3% by mass of all fibers constituting the top layer. The fibrillated rayon has a degree of beating of at most 700 cc, and has primary fibers of a predetermined fiber length and microfibers extending from the primary fibers. The microfibers are entangled with and/or hydrogen-bonded to at least either of other microfibers and other fibers. The back layer includes fibers containing no fibrillated rayon, the fibers entangled with and/or hydrogen-bonded to each other, or the back layer includes the fibrillated rayon in an amount smaller than that in the top layer. The microfibers of the fibrillated rayon are entangled with and/or hydrogen-bonded to at least either of other microfibers and other fibers.

摘要： There is disclosed a water-decomposable non-woven fabric including a first regenerated cellulose fiber having a fiber length of 3 mm or more to 5 mm or less, a second regenerated cellulose fiber having a fiber length of 6 mm or more to 10 mm or less, and a natural fiber having a fiber length of 10 mm or less, in which at least the second cellulose fiber is entangled with at least one of the first regenerated cellulose fiber, the second regenerated cellulose fiber and the natural fiber. This water-decomposable non-woven fabric is bulky with soft touch, and is also excellent in both water decomposability and wet strength.
