Abstract: 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.

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.
