Abstract
Official abstract text for this publication.
In one or more embodiments, the present invention is directed to a moisturizing tissue paper having excellent softness, smoothness, and strength. In various embodiments, the present invention provides a two-ply tissue paper containing a moisturizing agent having a basis weight per ply of 16.6 to 17.9 g/m2, a two-ply paper thickness of 143 to 159 μm, and containing a polyol, hyaluronic acid, a fatty acid ester-based compound, and a fatty acid amide-based compound.
First claim
Opening claim text (preview).
The invention claimed is: 1. A two-ply tissue paper comprising a moisturizing agent, wherein a basis weight per ply is 16.6 to 17.9 g/m 2 , a two-ply paper thickness is 143 to 159 μm, and all of a polyol, hyaluronic acid, a fatty acid ester-based compound, and a fatty acid amide-based compound are contained in the two-ply tissue paper, the content of a fatty acid ester-based compound is 0.10 to 0.50 parts by mass with respect to 100 parts by mass of a pulp fiber and the content of a fatty acid amide-based compound is 0.01 to 0.05 parts by mass with respect to 100 parts by mass of a pulp fiber, a wet tensile strength in CD is 36 cN/25 mm or more, and an evaluation value (T) determined by the following formula (1) is 97 or more, Evaluation value ( T )=(basis weight×two-ply paper thickness×moisture content)/(dry tensile strength in MD (machine direction)×dynamic friction coefficient average value measured by a pin-on-plate type friction test apparatus×friction coefficient maximum value measured by a pin-on-plate type friction test apparatus) (1).
