Abstract
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.
Claims15
Household tissue paper obtained by applying a ply process to two or more sheets of base paper,
- wherein first embossments and second embossments, arranged around the first embossments, are formed on an entire surface, 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.
A hydrolysable sheet comprising a multi-ply base paper sheet that is substantially water-dispersible, the multi-ply base paper sheet containing pulp and a water-soluble binder and being impregnated with an aqueous chemical agent, wherein
- a basis weight of the multi-ply base paper sheet is 30 gsm to 150 gsm,
- a content of the water-soluble binder increases towards a front surface and/or a back surface, and
- first embossments and second embossments, arranged around the first embossments, are formed on an entire surface, 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.
A hydrolysable sheet comprising a multi-ply base paper sheet that is substantially water-dispersible, the multi-ply base paper sheet containing pulp and a water-soluble binder and being impregnated with an aqueous chemical agent, wherein
- a basis weight of the multi-ply base paper sheet is 30 gsm to 150 gsm,
- when an abrasion resistance test by a rubbing fastness tester using a PP band as a pendulum is conducted three times both for an MD direction and a CD direction, two averages respectively for three measured values are greater than or equal to 40, and
- first embossments and second embossments, arranged around the first embossments, are formed on an entire surface, 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.
