Beschreibung
Zusammenfassung:	The present invention provides an absorption product, which comprises an absorption core body 1. The absorption core body 1 comprises: an upper permeable layer and a lower permeable layer, and the upper permeable layer and the lower permeable layer have an integrated polymer microporous foam structure, wherein a plurality of first permeable holes are provided in the upper permeable layer, a plurality of second permeable holes are provided in the lower permeable layer, and the aperture of the first permeable holes is larger than that of the second permeable holes. A hydrophilic surface layer 2 is provided on the upper surface of the absorption core body 1, and a water-repellent bottom layer 3 is provided on the lower surface thereof. The absorption core body 1 is obtained by reacting an acrylate monomer, modified acrylate, a cross-linking agent, a photoinitiator, an emulsifier and an initiator, wherein the modified acrylate is obtained by reacting the reaction product of isosorbide and glycidyl ether with acry
