At least one of these is added to the previous adhesive and mixed uniformly. In this case, the weight ratio of the humectant to the adhesive is preferably in the range of 30 to 70%.
- the weight ratio of the humectant to the adhesive is less than 30%, it becomes difficult to clearly suppress the effect of the present invention, that is, the deterioration of the texture of the sanitary paper accompanying the use of the adhesive. Conversely, when the weight ratio of the humectant to the adhesive exceeds 70%, the bonding strength between the two sheets is insufficient, and the sheets are likely to be separated.
- the paper quality improver is a sizing agent
- a rosin emulsion type, an alkyl ketene dimer type, an alkenyl succinic anhydride type, a styrene type polymer or the like commonly used in the papermaking field can be used as the sizing agent. It is not limited to. At least one of these is added to the previous adhesive and mixed uniformly.
- the weight ratio of the sizing agent to the adhesive is preferably in the range of 30 to 75%.
- the weight ratio of the sizing agent to the adhesive is less than 30%, it is difficult to improve the effect of the present invention, that is, the difficulty of tearing sanitary paper accompanying the use of the sizing agent.
- the weight ratio of the sizing agent to the adhesive exceeds 75%, the joining strength between the two sheets is insufficient and the sheets are easily separated.
- the weight ratio of the sizing agent to the pulp component contained in the stock for making paper is in the range of 0.1 to 1%.
- the weight ratio of the sizing agent to the pulp component contained in the paper stock is less than 0.1%, it can hardly be expected to improve the difficulty of sanitary paper tearing due to the use of the sizing agent.
- the weight ratio of the sizing agent to the pulp component contained in the stock exceeds 1%, the water disintegration property of the sanitary paper is impaired.
- the ratio of the adhesive, the humectant and the sizing agent is set in a range of 4: 3: 3 to 6: 2: 2 by weight. It is preferable to do.
- an embossed pattern is formed on the sheet exposed on the surface side of the sanitary paper, and the adhesive may further contain a colorant.
- a colorant In this case, an aqueous dye or the like can be generally employed as the colorant, but may be an aqueous pigment and is not limited thereto.
- the sheet exposed on the back side of the sanitary paper is embossed, and convex portions by this embossing can be formed over the entire area at a predetermined interval.
- the sheet that is not exposed on the front side or the back side of the sanitary paper is embossed and the embossed convex portions are spread over the entire area of the sheet. It may be formed by.
- the sheet exposed on the back side of the sanitary paper is embossed, and the density of the projections at the center side of the sheet can be set higher than the density of the projections at the edge of the sheet.
