The invention relates to the technical field of spunlace non-woven, and discloses a combined spunlace non-woven fabric for a personal hygiene nursing product water absorption surface layer and a preparation method of the non-woven fabric. The spunlace non-woven fabric comprises a first fiber layer and a second fiber layer, the first fiber layer comprises hydrophilic fibers, the second fiber layercomprises hydrophobic fibers, the fibers in the first fiber layer and the second fiber layer are entangled each other, a plurality of projections and a plurality of through holes are distributed on the surface of the first fiber layer, and the through holes penetrate the second fiber layer. The non-woven fabric comprises double-layer fibers with different solution absorption performances, one surface contacting with human skins has hydrophilicity, softness and skin-friendly performance of the fabric cannot be affected, the other surface without contacting with the human skins has hydrophobicity, so that ratio of hydrophilic fibers can be reduced, liquid storage amount of the surface layer is reduced, liquid absorbed by the first fiber layer can rapidly pass the second fiber layer to entera flow guide layer, and dry and comfortable performances of surface layer materials are improved.
