摘要：
An absorbent core with an efficient flow guide property and breathability, and method for manufacturing same. The absorbent core comprises a surface layer (4), a bottom layer (5), and an absorbent layer between the surface layer (4) and the bottom layer (5)； the absorbent layer comprises a non-woven fabric layer (6) attached to the lower surface of the surface layer (4)； a super absorbent polymer is uniformly scattered in the non-woven fabric layer (6)； the surface layer (4) and the non-woven fabric layer (6) are attached to each other to form a composite layer； flow guide grooves (7) are formed on the composite layer and divide the absorbent core into a plurality of absorbent regions； the composite layer possessing the flow guide grooves (7) is connected with the upper surface of the bottom layer (5)； a super absorbent polymer is uniformly scattered between the lower surface of the non-woven fabric layer (6) and the upper surface of the bottom layer (5). According to the absorbent core, the plasticization extent of the non-woven fabric (6) can be minimized, the softness and comfort can be enhanced, and the tactile impression can be improved. Super absorbent polymers with different properties are matchedly scattered between layers of the absorbent core, and obvious protrusions would be formed after liquid is absorbed by the absorbent core； the absorbent core feels soft and comfortable and is good in breathability, high in absorbed liquid spreading speed, and small in skin contact area.L'invention porte sur un noyau absorbant présentant une propriété de guidage d'écoulement efficace et une bonne perméabilité à l'air, et sur son procédé de fabrication. Le noyau absorbant comprend une couche de surface (4), une couche inférieure (5) et une couche absorbante entre la couche de surface (4) et la couche inférieure (5). La couche absorbante comprend une couche de tissu non tissé (6) fixée à la surface inférieure de la couche de surface (4). Un polymère superabsorbant est u
