the improvement is that the upper layer material and the lower layer material of the composite core body of the absorbent article are materials of non-woven fabrics, dust-free paper and toilet paper.

the improvement is that the fixed connection part of the lower surface of the hydrophilic surface layer and the upper surface of the third absorption core of the composite core body absorption article is provided with 2-3 adhesive layers.

the improvement is that in the composite core body, a fourth absorbent core and/or a fifth absorbent core is arranged between the th absorbent core and the second absorbent core, and the transverse interval between two adjacent absorbent cores is between 5 and 10 mm.

the improvement is that the lateral space between the absorption core and the second absorption core is 10-20 mm.

the improvement is that the longitudinal length of the liquid permeable part of the liquid permeable surface layer is 15-30 mm longer than the longitudinal length of the composite core body.

By adopting the technical scheme, the core body prepared by mixing the fluff pulp and the water-absorbing resin has the advantages of high absorption speed, good flow guide effect and the like, and also has the defects of relatively large reverse osmosis amount, low core body strength and the like; especially when adopting compound core structure, the fine hair oar and the resin mixture that absorbs water of low square grammes per square gra.
