Problems solved by technology

[0014] In addition, in the structure of Patent Document 2 (the nested laminated structure), although the contact area with the object of use can be reduced compared with the pointed-to-pointed laminated structure, due to the embossing in the sanitary tissue paper Since the space is small, there is a problem that it is difficult to absorb oil and the like due to the deformation of the fine embossed space when a load is applied during use, and the absorbed oil oozes out (see Figure 18 ~ Figure 21 )

Embodiment 1

[0203] In Example 1, using Figure 1 to Figure 4 The shown kitchen paper 100 of the first embodiment. In Example 1, as the base paper, pulp with a fiber raw material of 100% by mass and a weight per square meter of 22.1 g / m 2 Two sheets of crepe paper 10, 20 of the base paper are stacked up and down (two layers). Regarding the embossing conditions, a nested form is adopted, and the area of ​​the embossed convex parts EC1 and EC2 is set to 1.1mm 2 , the shape of the embossed convex portions EC1, EC2 is set to be a quadrangle, the pattern of the non-embossed portion 50 is set to be a cross and has no intersection in the cross, and the total number of embossed convex portions EC1, EC2 The number is 2090 / 144cm 2 , the glue coating area ratio of the embossed convex portion EC1 of the crepe paper 10 and the non-embossed convex portion NE2 of the crepe paper 20 (the coating area ratio of the non-embossed convex portion NE1 of the crepe paper 10 and the embossed convex portion EC...

Embodiment 2

[0205] In Example 2, using Figure 5 and Figure 6 The shown kitchen paper 100 of the second embodiment. In embodiment 2, the weight per square meter of base paper is 21.5g / m 2 , in the embossing condition, each pattern formed in the non-embossed regions 51, 53 of the non-embossed part 50 is made into a shape in which four elongated rectangles are arranged at predetermined intervals, and the non-embossed part Each pattern formed in the non-embossed regions 52 and 54 of 50 is made into a shape in which 12 elongated rectangles are arranged at predetermined intervals, and the total number of embossed convex parts EC1 and EC2 is 2105 pieces / 144cm 2 , assuming the total volume of all embossed convex parts EC1 and EC2 is 10759mm 2 , except that the area ratio of the non-embossed portion 50 is 10.7%, it is the same as in Example 1. Table 1 shows the conditions and results of Example 2.

Embodiment 3

[0207] In Example 3, using Figure 7 ~ Figure 10Kitchen paper 100 of the third embodiment shown. In Example 3, it is the same as in Example 1 except that the non-embossed portion 60 is formed on the crepe paper 20 . Table 1 shows the conditions and results of Example 3.

Abstract

Provided is sanitary tissue paper that includes: a first sheet on the front and rear surfaces of which a plurality of embossed protrusions and a plurality of embossed recesses that correspond to the embossed protrusions are formed; and a second sheet on the front and rear surfaces of which a plurality of embossed protrusions and a plurality of embossed recesses that correspond to the embossed protrusions are formed. The first sheet and the second sheet are integrated with each other by making the surfaces on which the embossed protrusions are formed face each other in a nested manner. The first sheet and the second sheet have embossed portions in which a plurality of embossed protrusions and a plurality of non-embossed protrusions are formed. At least either one of the first sheet and thesecond sheet has a non-embossed portion in which the plurality of embossed protrusions and the plurality of non-embossed protrusions are not formed. The non-embossed portion has a shape not having anintersecting part.

Description

technical field [0001] This invention relates to sanitary tissue paper. Background technique [0002] As sanitary thin paper such as kitchen paper, sanitary thin paper having a laminated structure in which sheets of embossed crepe paper or the like are laminated is known. In conventional sanitary tissue papers, each sheet is embossed in order to impart oil and water absorption performance, thereby forming convex portions on one side (hereinafter referred to as embossed convex portions), and embossing convex portions on the other side. Recesses corresponding to the protrusions (hereinafter, referred to as embossed recesses) are formed on the surface. Then, these sheets are laminated, thereby forming spaces (embossed spaces) between the laminated sheets, and absorbed oil and the like are held in the embossed spaces. [0003] In addition, in this kind of sanitary tissue paper, in order to improve the appearance and absorption performance (moisture or oil absorption and retent...
