摘要： After laminating together the first sheets crepe-processed at a high crepe ratio and the second sheet crepe-processed at a crepe ratio lower than that of the first sheet or not crepe-processed, the sheets are bonded together at bonding parts at a given pitch in rows. When the resulting bonded sheets are impregnated with a liquid, expansions are generated between the rows of bonding parts due to the difference in ratios of the elongation of the two sheets. The expansions take on the shape of large wrinkle according to the pitch of the bonding parts. At the production process of the sheet, the sheet is crepe-processed containing water at a preset ratio, whereby small wrinkles as residual crepe wrinkles are formed on the sheet surface. The large wrinkles and the small wrinkles can enhance the wiping effect.

摘要： Conventional water-decomposable fibrous sheets for cleaning sheets capable of being disposed of in toilets and others do not have well-balanced decomposability in water and strength. The water-decomposable fibrous sheet containing from 5 to 100% by mass of fibrillated rayon having a fiber length of at most 10 mm and having a degree of beating of at most 700 cc, optionally along with other fibers having a length of at most 10 mm, has good decomposability in water and high wet strength. When subjected to water-jetting treatment, it becomes more bulky to have a soft feel.
