Abstract
A fibrous sheet containing cotton fibers and at least two kinds of synthetic fibers is disclosed. The synthetic fibers form a nonwoven fabric. The cotton fibers enter a fiber network of the nonwoven fabric and interlace with the fiber network thereby to form a cotton fiber layer on one side of the nonwoven fabric, with part of the cotton fiber layer entering the nonwoven fabric. The synthetic fibers contain a combination of heat fusible fiber (a) and heat fusible fiber (b) having a small thickness than the fiber (a) or a combination of the fiber (a) and a fiber (c) that is not thermally bonded with the fiber (a).
Claims10
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.
A fibrous sheet containing cotton fibers and at least two different kinds of synthetic fibers,
- the at least two kinds of synthetic fibers form 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 both sides of the nonwoven fabric, with part of each of the cotton fiber layers 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.
