The invention relates to enhanced oil absorbent cotton which comprises an oil absorbent film layer and non-woven fabric layers arranged on two sides of the oil absorbent film layer, wherein the oil absorbent film layer is prepared by the following steps: S1, preparing polyisobutyl acrylate and dissolving a certain amount of polyisobutyl acrylate in a first organic solvent to form a second solution; S2, preparing polyacrylonitrile and dissolving a certain amount of polyacrylonitrile in a second organic solvent to form a second solution, wherein the mass ratio of polyacrylonitrile and polyisobutyl acrylate is 0.2-3; and S3, carrying out electrostatic spinning on the first and second solutions through electrostatic spinning channels respectively at the same time, wherein the electrostatic spinning conditions are as follows: the voltage is 5-25kV, the receiving distance is 5-20cm, the nozzle moving speed is 0.5-2mm/s, the rotating speed of a receiver is 100-500rmp, and the electrostatic spinning time is 5-10h. The spinning film is the oil absorbent film layer which is 1-3mm thick. The enhanced oil absorbent cotton provided by the invention not only has a high oil absorption rate, but also has relatively high mechanical strength.
