The present invention discloses a highly breathable super absorbent diaper pad and a preparation method thereof, which belongs to the technical field of diaper pads, and comprises a protective layer, an absorption layer and an anti-reverse osmosis layer from top to bottom, wherein the protective layer is composed of antibacterial modified soybean protein viscose fiber, polyester fiber and ES fiber, the absorption layer is composed of super absorbent fiber and antibacterial modified soybean protein viscose fiber, and the anti-reverse osmosis layer is composed of super absorbent fiber and antibacterial modified soybean protein viscose fiber. The present invention adopts a three-layer non-woven fabric structure with gradual changes in pore size, hydrophilicity and disorder, which can accelerate urine absorption and prevent reverse osmosis; the present invention treats soybean protein to improve hydrophilicity, antibacterial property and air permeability, and the amphiphilicity can make urine diffuse and be absorbed faster and adjust water absorption balance; the present invention utilizes mannitol, hexafluorobutyl methacrylate and other ingredients to make the fiber have excellent water absorption, reduce surface energy, and form a network structure with block copolymer and sodium polyacrylate to improve water absorption and air permeability.

This invention provides oleanolic acid-modified HG-type pectin nanomicelles, their preparation method, and applications. The preparation method of the HG-type pectin nanomicelles includes: esterifying 3,3'-dithiodipropionic acid and oleanolic acid to obtain SS-OA; esterifying SS-OA and HG-type pectin to obtain oleanolic acid-modified HG-type pectin; dissolving the oleanolic acid-modified HG-type pectin and dispersing it ultrasonically to obtain oleanolic acid-modified HG-type pectin nanomicelles. The oleanolic acid-modified HG-type pectin nanomicelles of this invention combine the functional activities of HG-type pectin and oleanolic acid, as well as the redox responsiveness of 3,3'-dithiodipropionic acid, constructing nanomicelles that respond to ROS generated during alcohol metabolism. They exhibit amphiphilicity and good biocompatibility, and can be used to prepare drugs to alleviate chronic alcoholic liver injury.
