[0030] The arrangement alternately refers to that the first embossed depressions 13 are arranged between adjacent first embossed protrusions 11, and the first embossed protrusions 11 are arranged between adjacent first embossed depressions 13, forming a pattern of first embossed protrusions 11, first embossed depressions 13, first embossed protrusions 11, first embossed depressions 13, and so on, and the arrangement pattern of the second embossed protrusions 12 and the second embossed depressions 14 is the same as that of the first embossed protrusions 11 and the first embossed depressions 13, which will not be described herein.

[0031] It can be understood that, by using the above arrangement pattern, the first surface 101 and the second surface 102 of the base body 10 can have a substantially uniform pattern, more specifically, the first surface 101 and the second surface 102 of the base body 10 can both have embossed protrusions and embossed depressions at the same time, and the embossed protrusions and the embossed depressions have the same pattern, thereby facilitating use.

[0032] It can be understood that the first embossed protrusion 11 and the second embossed recess 14 are arranged correspondingly, which means that when the second embossed recess 14 is formed by recessing the base body 10 from the second surface 102 to the first surface 101, the first surface 101 is correspondingly protruded away from the first surface 101 to form the first embossed protrusion 11. Similarly, the second embossed protrusion 12 and the first embossed recess 13 are arranged correspondingly, which means that when the first embossed recess 13 is formed by recessing the base body 10 from the first surface 101 to the second surface 102, the second surface 102 is correspondingly protruded away from the second surface 102 to form the second embossed protrusion 12. In a specific embodiment, the first embossed protrusion 11, the second embossed recess 14, the second embossed protrusion 12 and the first embossed recess 13 can be realized by embossing roller groups, which include a pair of rollers arranged in parallel and placed on the same axis, i.e. an embossing roller and a bottom roller. The embossing roller includes an upper roller body, an upper protruding part extending radially outward on the upper roller body, and an upper recessed part recessed inward on the upper roller body. The bottom roller includes a lower roller body, a lower recessed part recessed inward on the lower roller body, and a lower protruding part extending radially outward on the lower roller body. The upper protruding part corresponds to the lower recessed part, and the lower protruding part corresponds to the upper recessed part. There is a gap between the embossing roller and the bottom roller. The base body 10 passes through the gap between the two rollers. After passing through the gap between the two rollers, the first embossed protrusion 11 and the first embossed recess 13 are formed on the first surface 101, and the second embossed protrusion 12 and the second embossed recess 14 are formed on the second surface 102.

[0033] Further, the first embossed protrusion 11 is the same as the second embossed protrusion 12, and the first embossed recess 13 is the same as the second embossed recess 14. The same means that the shape and size of the embossed protrusion are the same, and the shape and size of the embossed recess are the same.

[0034] Further, the first embossed protrusion 11 is in the shape of a prism, which includes a first end face 111. The area of the first end face 111 is greater than or equal to 3.5 mm², so that the first embossed protrusion 11 has a larger contact area. Preferably, the first embossed protrusion 11 is a quadrangular prism.

[0035] It can be understood that the second embossed protrusion 12 includes a second end face 121, the first embossed recess 13 includes a first opening 131, and the second embossed recess 14 includes a second opening 141. The area of the first opening 131 is equal to that of the first end face 111, and the area of the second opening 141 is equal to that of the second end face 121.

[0036] Further, the distance between adjacent first embossed protrusions 11 is defined as D1, and D1≥4 mm. More preferably, D1=4.2-5.5 mm.

[0037] Further, the height of the first embossed protrusion 11 is greater than or equal to 0.6 mm, preferably, the height of the first embossed protrusion 11 is 1-3 mm.

[0038] Further, the depth of the first embossed recess 13 and the second embossed recess 14 is greater than or equal to 1.4 mm, preferably, the depth of the first embossed recess 13 and the second embossed recess 14 is 1.5-2.5 mm.

[0039] Further, the distance between the adjacent first embossed protrusion 11 and the first embossed recess 13 is defined as D2, then D2≤2 mm, more preferably, D2=0.5-1.5 mm.

[0040] It is found in practice that, by the above setting, on the one hand, the embossed patterns on both sides of the household paper are almost completely consistent, so that the use on both sides has the same effect; on the other hand, the above setting makes the embossed protrusions and recesses have relatively rough contact surfaces, which can form better absorption effect on the water stains on the foot surface during wiping and can form massage effect on the foot surface, so that the use of the foot is more comfortable; on the third hand, compared with the existing embossing setting, the average water absorption is increased by 8.3% through the above setting.

[0041] Please refer to Figure 7 , in Figure 7 , the cross section of the household paper at A-A is shown, in the third embodiment, the first embossed protrusion includes low protrusion 311 and high protrusion 312, wherein the height of the high protrusion 312 is greater than that of the low protrusion 311, at the same time, the high protrusion 312 and the low protrusion 311 are arranged alternately, which means that the adjacent high protrusions 312 are arranged with low protrusions 311, and the adjacent low protrusions 311 are arranged with high protrusions 312, to form the pattern of low protrusion 311, high protrusion 312, low protrusion 311, high protrusion 312…….

[0042] Further, the height of the high protrusion 312 is higher than that of the low protrusion 311 by more than 0.2 mm.

[0043] Please refer to Figures 4-6 , in Figures 4-6 , the cross section of the household paper at A-A is shown, in the third embodiment, the first embossed protrusion includes low protrusion 311 and high protrusion 312, wherein the height of the high protrusion 312 is greater than that of the low protrusion 311, at the same time, the high protrusion 312 and the low protrusion 311 are arranged alternately, which means that the adjacent high protrusions 312 are arranged with low protrusions 311, and the adjacent low protrusions 311 are arranged with high protrusions 312, to form the pattern of low protrusion 311, high protrusion 312, low protrusion 311, high protrusion 312…….

[0044] The first embossing protrusion 21 and the first embossing recess 23 are arranged in a staggered manner. Specifically, the first embossing recess 23 is located in a first region 25 defined by four first embossing protrusions 21 adjacent to each other, and a first virtual straight line 251 connecting the first embossing protrusions 21 at opposite corners passes through the first embossing recess 23. Similarly, the first embossing protrusion 21 is located in a second region 26 defined by four first embossing recesses 23 adjacent to each other, and a second virtual straight line 261 connecting the first embossing recesses 23 at opposite corners passes through the first embossing protrusion 21. Through the above arrangement, the first embossing protrusion 21 and the first embossing recess 23 are always arranged in a staggered manner, and the second embossing protrusion 22 and the second embossing recess 24 are also arranged in a staggered manner. In this arrangement, the embossing patterns of the first surface 201 and the second surface 202 are almost identical, and the spacing between the first embossing protrusions 21, the first embossing recesses 23, the second embossing protrusions 22, and the second embossing recesses 24 can be set larger, presenting a more sparse embossing pattern than the first embodiment. This allows the first end surface 211 and the second end surface 221 to be arranged larger, thereby having a larger absorption area and presenting a rougher feel, thereby meeting the needs of different consumers.

[0045] It can be understood that the first embossing recess 23 is arranged separately from the first embossing protrusion 21, and the second embossing protrusion 22 is arranged separately from the second embossing recess 24.
