According to some preferred embodiments, the wet-process papermaking super absorbent resin absorbent paper is obtained by compounding super absorbent resin evenly distributed between two raw paper layers through wet-process papermaking; wherein the contents of the components are as follows: 60-90 wt% of base paper and 10-40 wt% of super absorbent resin particles;

The wet-process papermaking super absorbent resin absorbent paper is obtained by uniformly distributing super absorbent resin between two raw paper layers through wet-process papermaking, and specifically comprises the following steps: 1) Making upper and lower base papers by wet papermaking; 2) Uniformly broadcasting the super absorbent resin particles on the lower base paper; wherein, the percentage content of the base paper and the super absorbent resin particles is: 60-90 wt% of base paper and 10-40 wt% of super absorbent resin particles; 3) Pressing the upper base paper with the lower base paper sprayed with the super absorbent resin particles to obtain composite paper; 4) And drying and shaping the laminated composite paper at 105-120 ℃ to obtain the wet-process super absorbent resin absorbent paper.

The wet-process high-water-absorption resin absorbent paper prepared by adopting the base paper and the high-water-absorption resin particles with the percentages is soft and comfortable, and has good absorption performance and good dryness. If the content of the base paper is more than 90wt%, the wet-process super absorbent resin absorbent paper has poor absorption performance and poor dryness; if the content of the base paper is less than 60wt%, the wet-process super absorbent resin absorbent paper has poor softness, is uncomfortable and has high cost.

In the invention, the gram weight of the wet-process super absorbent resin absorbent paper is 20-300 g/m ² The inventors found that when the gram weight of the wet-process super absorbent resin absorbent paper is less than 20g/m ² When the addition amount of the super absorbent resin is small, the wet method is used for manufacturing the super absorbent resin absorbent paper, so that the liquid absorption effect is poor; when the gram weight of the wet-process super absorbent resin absorbent paper is higher than 300g/m ² When the high water absorption resin is added, the total weight of the wet-process high water absorption resin absorbent paper is larger, so that the portability of the sanitary absorbent articles is reduced. Therefore, on the basis of ensuring the high water absorption of the wet-process super absorbent resin absorbent paper, the wet-process super absorbent resin absorbent paper is lighter and thinner, and the gram weight of the wet-process super absorbent resin absorbent paper is preferably in the range.

The first test method comprises the following steps: taking animal blood for 2 times, each time of 5mL, and recording the time of finishing each time of absorption as the absorption speed in s at intervals of 10 minutes for 2 times; reverse osmosis is to put 10g filter paper on an absorbing article for 1min under the pressure of a weight of 1.2kg after 5mL of animal blood is added for 5min each time, and weigh the gram weight added by the filter paper in g; diffusion is a length measurement in the transverse direction in cm 1 minute before the second reverse osmosis.

And a second test method: the wearing trial was performed on the absorbent articles of examples 1 to 5 and comparative examples 1 to 11, respectively, with 20 persons randomly found, under the premise of ensuring other sanitary conditions, and the dry and refreshing effect was judged by changing every four hours during the menstrual period.

And a test method III: 20 persons are randomly found, and wearing trial is carried out on the absorbent articles of the examples 1-5 and the comparative examples 1-11 respectively, so as to judge the antibacterial and deodorizing effects.

Table 1: results of performance testing of the absorbent articles of examples 1 to 5 and comparative examples 1 to 11.

TABLE 1

The first absorption speed, the second absorption speed, the first reverse osmosis, the second reverse osmosis and the transverse diffusion length performance are tested by the first reference test method; a second test reference test method for dryness effect; and a test reference test method III for antibacterial and deodorizing effects.

As can be seen from the above comparative data, compared with comparative examples 1 to 11, the absorbent articles prepared in examples 1 to 5 have the advantages of high absorption speed, low reverse osmosis, good dryness and the like, and meanwhile, the liquid-permeable surface layer adopts the antibacterial spun-laced nonwoven fabric obtained by compounding aloe viscose fibers, chitosan fibers and bamboo charcoal fibers, so that the absorbent articles have excellent antibacterial and deodorizing effects. The superconducting structure of the comparative example 1 is two layers of wet-process super absorbent resin absorbent paper, which is not folded, and is easy to be laterally diffused after liquid infiltration, so that the lateral diffusion length value is larger than that of the examples; in comparative examples 3 to 4, through holes are formed in the region of the folded portion near the center portion, and the liquid is easily laterally diffused after infiltration, so that the lateral diffusion length value is larger than that of the examples; however, in comparative example 3, a through hole was also provided in the region of the folded portion near the open end, so that the liquid permeation rate and the liquid absorption rate were faster than those of comparative example 4; the first absorption layers of comparative examples 7-8 were not perforated, and the liquid permeation rate and absorption rate were slower than those of the comparative examples; the liquid-permeable surface layer of comparative example 10 is a common spunlaced non-woven fabric, and has no antibacterial component, so that the antibacterial and deodorizing effects are poorer than those of the examples; the absorption layer of comparative example 11 is made of high water absorption resin wrapped by non-woven fabric, and has poor absorption effect and large reverse osmosis quantity, thereby affecting the bacteriostasis and odor removal effects of the liquid-permeable surface layer.
