PROVIDED IS A WATER-DECOMPOSABLE FIBROUS SHEET INCLUDES FIBERS CONTAINING FIBRILLATED RAYON. THE FIBRILLATED RAYON HAS PRIMARY FIBERS OF A PREDETERMINED FIBER LENGTH AND MICROFIBERS EXTENDING FROM THE PRIMARY FIBERS. THE FIBRILLATED RAYON INCLUDES A FIRST TYPE OF 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 TYPE OF 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. THE MICROFIBERS EXTENDING FROM THE FIRST AND SECOND TYPES OF FIBRILLATED RAYON ARE ENTANGLED WITH AND/OR HYDROGEN-BONDED TO AT LEAST EITHER OF OTHER MICROFIBERS AND OTHER FIBERS. |
