Abstract:
A wet sheet for cleaning includes multiple layers and is impregnated with a chemical solution. The wet sheet includes hydrophobic fiber layers arranged in a front surface layer and a back surface layer, and a hydrophilic fiber layer arranged in an intermediate layer. The hydrophobic fiber layers have an interlaced part with a high fiber density where the hydrophobic fiber layers are interlaced with the hydrophilic fiber layer. The interlaced part has at least one slightly interlaced part and at least one highly interlaced part which is formed in a dent shape and which is interlaced with a higher fiber density. The highly interlaced part is formed in an area ratio of 10 to 20% to an area of the front surface layer or the back surface layer. Static friction resistance of the wet sheet for cleaning is lower than kinetic friction resistance of the wet sheet for cleaning.
