Abrégé

A fiber web containing hardwood pulp is impregnated with a chemical solution that contains a moisturizing component such as glycerin, moisture, an oily component such as hydrocarbons, and a vegetable powder such as corn starch. The vegetable powder enters between pulp fibers of the fiber web in which hydrogen bonds are relaxed by the moisturizing component and the oily component, thereby spontaneously raising some of the pulp fibers in a surface of the fiber web. Accordingly, a fiber web product that is excellent in texture characteristics such as a smooth raised feeling, softness, and moistness, generates less dust such as powder or pulp fibers, and has sufficient strength, and a manufacturing method of the same are provided.

According to the present invention, a fiber web including a broadleaf tree pulp is impregnated with a chemical liquid, and the chemical liquid contains a moisturizing component such as glycerin, water, an oil component such as a hydrocarbon, and a plant-based powder such as corn starch. A portion of pulp fibers at the surface of the fiber web is spontaneously napped by the plant-based powder penetrating into between pulp fibers of the fiber web in which hydrogen bonds are relaxed by the moisturizing component and the oil component. As a result, provided are: a fiber web product that has excellent texture characteristics such as smooth nap feeling, softness, and moist feeling, has less dust such as powder and pulp fibers, and has sufficient strength; and a production method for the fiber web product.

Provided are a device and method for manufacturing embossed crepe paper having concavo-convex-shaped micro-embossment, with which productivity is excellent and energy costs are low. A device for manufacturing crepe paper that uses a paper machine having at least a dryer section (40) which heats and dries a damp fibrous web (T), and a crepe doctor (50) which forms creping in the heated and dried fibrous web (T) to obtain dry crepe paper (D), wherein are disposed, in the latter stage of the crepe doctor (50), a spray device (63) or a transfer roller (64) serving as a treatment liquid supply unit which supplies a treatment liquid for impregnating the dry crepe paper (D) and which contains at least water, and an embossing roller (61) which has residual heat from the heating and drying by the dryer section (40) and which forms embossment in the dry crepe paper (D) impregnated with the treatment liquid.
