Abstract:
This wet sheet for cleaning (1) of the present invention, which is composed of a plurality of layers and impregnated with a chemical solution, is provided with: hydrophobic fiber layers (3) respectively disposed on a front surface layer and a rear surface layer; and a hydrophilic fiber layer (2) disposed on an intermediate layer interposed between the hydrophobic fiber layers (3). The hydrophobic fiber layers (3) have an interlaced part which is interlaced with the hydrophilic fiber layer (2) at a high fiber density. The interlaced part is provided, on the front surface layer and the rear surface layer, with: a low interlaced part (32); and a high interlaced part (32) interlaced at a higher fiber density than the low interlaced part (32), and formed in a concave shape. The high interlaced part (31) is formed to have an area ratio of 10-20% with respect to the area in a plane view of the front surface layer or the rear surface layer.
