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 wet-process is used for making super absorbent resin absorbent paperGram weight 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.

And a second test method: 20 persons are randomly found, the absorbent articles of examples 1-5 and comparative examples 1-10 are put on a wearing trial, and the antibacterial and deodorizing effects are judged.
