摘要： The present disclosure includes a head part to which a cleaning sheet is attached; and a handle part which is connected to the head part and which is for gripping by a user. The head part includes a top surface part which forms an upper surface side and to which the handle part is connected; and a bottom surface part which forms a lower surface side. The bottom surface part is formed to be freely attachable/detachable with respect to the top surface part. Due to this configuration, it is possible to provide a cleaning tool which can easily clean both low places such as a floor surface and high places such as a ceiling and the upper part of a wall.

摘要： A toilet cleaning sheet 100 includes a multi-ply base paper sheet that is substantially water-dispersible. The multi-ply base paper sheet contains pulp and a water-soluble binder and is impregnated with an aqueous chemical agent. The basis weight of the multi-ply base paper sheet is 30 gsm to 150 gsm, and the content of the water-soluble binder increases towards a front surface and/or a back surface.

摘要： This cleaning sheet is provided with an embossed part in which the sheet is compressed in the thickness direction. The cleaning sheet is provided with outer layers, forming the surfaces of the sheet; and an inner layer sandwiched between the outer layers. In the boundary areas between the outer layers, and the inner layer, the fibers of the layers are entangled. This allows for a sheet that better retains the raised and sunken shapes embossed therethrough and exhibits excellent collecting performance.

摘要： Household tissue paper is obtained by applying a ply process to two or more sheets of base paper. First embossments and second embossments, arranged around the first embossments, are formed on an entire surface of the household tissue paper, a shape of a protruding part of each of the second embossments differing from a shape of a protruding part of each of the first embossments. Hence, because a contact area with an object to be cleaned or the like can be increased, it is possible to enhance surface strength of the household tissue paper being embossed and to enhance wiping performance.
