Patent ID: 7452834

Claim:
A fibrous sheet containing cotton fibers and at least two different kinds of synthetic fibers, the at least two kinds of synthetic fibers forming nonwoven fabric, the cotton fibers entering a fiber network of the nonwoven fabric while being entangled with the fiber network to form a cotton fiber layer on one side of the nonwoven fabric, with part of the cotton fiber layer being in the nonwoven fabric, and the at least two kinds of the synthetic fibers including a combination of a heat fusible fiber (a) and a heat fusible fiber (b) having a smaller thickness than the heat fusible fiber (a) or a combination of the fiber (a) and a fiber (c) which is not thermally bonded with the heat fusible fiber (a); and wherein the distance between fibers gradually decreases from the side with the cotton fiber layer being presented to the center of the thickness of the fibrous sheet.
