Abstract

The invention discloses a method for preparing a composite absorption core and the composite absorption core prepared by the method. The method includes the steps: (1) spraying a first adhesive layeron the upper side face of a bottom layer; (2) sprinkling first imbibition materials for forming a lower water absorption layer on the upper side face of the bottom layer with the sprayed first adhesive layer, and laying a middle absorption layer on the upper portion of the lower water absorption layer; (3) spraying a second adhesive layer on the lower side face of a surface layer, and sprinkling second imbibition materials for forming an upper water absorption layer on the lower side face of a surface layer; (4) covering the middle absorption layer made of materials obtained in the step (2) with materials obtained in the step (3) in such a manner that the side face of the upper water absorption layer is downward; (5) compacting the materials to obtain the composite absorption core. The composite absorption core prepared by the method has the advantages of good dry and comfortable property, avoidance of lumping, fault and hardening in expansion, high liquid infiltration and diffusion speed, less return permeability and the like.

Description

technical field [0001] The invention relates to the field of composite absorbent cores, in particular to a method for manufacturing composite absorbent cores and the composite absorbent core produced by the method. Background technique [0002] In the prior art, the composite absorbent core generally includes a surface layer, a bottom layer and an intermediate layer arranged between the surface layer and the bottom layer, and the absorbent material is fixed on the surface of the intermediate layer by means of bonding or the like. When the composite absorbent core touches liquid, the liquid passes through the surface layer to the middle layer, and is absorbed and retained by the absorbent material fixed on the middle layer to play the role of absorbing liquid. Thus, the amount of fluid that the absorbent core can absorb is determined by the amount and absorbent properties of the absorbent material. In this structure, since the absorbent material is usually distributed betwee...
