(57) [Summary] [Purpose] To create a fiber web with high moisture content, such as paper and non-woven fabric, which is highly safe, flexible and soft to the touch, and suitable for food, hygiene and household applications. provide. [Structure] At least one of hygroscopic salts, polyhydric alcohols and sugars, or one of these and a water-retaining sizing agent is added to a fiber web in an amount of 1.0 to Contains 300% by weight. These agents are preferably foods or food additives. When the web is in a wet state during papermaking of the fibrous web, it is impregnated by spraying or the like, or after the fibrous web is made into paper, the web is impregnated with the above-mentioned chemical to produce the web. The above-mentioned medicine absorbs moisture in the air and retains water to increase the content of moisture, thereby providing flexibility, It improves the texture and realizes a web that is not easily affected by changes in the humidity of the outside air, does not hinder the entanglement of fibers, and improves the adhesiveness to reduce the generation of web scraps. |
