Pulp layer and lower sap layers are coated with the first hydrophilic nonwoven fabrics, and the upper and lower surface of the polymer material layer is evenly distributed with plural number
A heat fusion joint, each heat fusion joint are distributed in matrix form, the lower surface of the upper layer absorptive core and lower layer's absorptive core
It is provided with several sap on upper surface and absorbs block, each sap absorbs block and is resisted against the institute of the heat fusion joint on polymer material layer
The region surrounded is sprayed with sap material on the upper surface of the upper layer absorptive core, and is covered with layer of non-woven fabric, described
Non-woven fabrics is connect by heating item with upper layer absorptive core, is provided with guide layer on the non-woven fabrics.
Further, it is fluted that the setting of block corresponding section is absorbed on the polymer material layer with each sap, it is described recessed
The depth of slot is less than the height that sap absorbs block.
Further, the upper layer absorptive core and lower layer's absorptive core are that wood pulp is mixed with sap, and passes through the second parent
Water non-woven fabrics cladding.
Further, air hole is provided on the upper layer absorptive core and lower layer's absorptive core.
By using preceding solution, the beneficial effects of the utility model are: the utility model absorbent item, passes through macromolecule
Upper sap layer, wood pulp layer and sap layer lower are set in material layer, and by the way that heat fusion joint is arranged so that upper sap layers with lower sap layers very
Good is fixed on wood pulp layer, while spraying water sap material, and non-woven fabrics and guide layer in the upper surface of upper layer absorptive core
It is connect with upper layer absorptive core by heating item, prevents from agglomerating after absorbing expansion, and the lower infiltration of the discharged liquid of heat fusion joint quickening
Speed realizes quickly water suction, reduces discharged liquid in the residence time of liquid permeability surface layer, and reduce the aqueous of upper layer absorptive core
Amount increases comfort so that being evenly distributed after polymer material layer water suction；Further, the sap of setting absorbs block, Yi Jishe
The groove set is used to cooperate with sap water suction block, increases contact area between the two, accelerates the infiltration rate of discharged liquid, reduces
The absorbent time of polymer material layer, and there is upper layer absorptive core and polymer material layer in the sap water suction block being arranged
Buffer gap increases gas permeability.
