A wet cleaning sheethas a liquid retentive sheetmade of a fibrous material or a cellular material and impregnated with a predetermined amount of a detergent, etc., a liquid impermeable sheetdisposed on one side of the liquid retentive sheet, and a liquid gradual-releasing sheet made of a fibrous material and less air permeable than the liquid retentive sheetdisposed on the other side of the liquid retentive sheet. The liquid impermeable sheethas a bag shape with openingson one side thereof. The liquid retentive sheet is held in the bag and releases the detergent, etc. through the openings. The liquid gradual-releasing sheet has an air permeability of 0.05 to 6 m/kPa&#xb7;s thereby to control the gradual release of the detergent, etc.

Wet sheet for cleaning

A bulky sheet comprising a fiber aggregate formed by water needling of a fiber web is disclosed. The bulky sheet has a number of projections and depressions comprising the fiber aggregate. The projections and the depressions is formed both by rearrangement of the constituting fibers of the fiber aggregate by water needling of the fiber aggregate and by the multiple bending manner of the fiber aggregate along the thickness direction thereof. The projections and the depressions retains the shape thereof by themselves.
