Abstract
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.
