The invention relates to the field of leather processing, in particular to a non-woven fabric impregnation device and an impregnation method thereof.The non-woven fabric impregnation device comprises an impregnation device, a conveying device and a heating device, and the conveying device and the heating device are both located on the upper portion of the impregnation device and communicate with the impregnation device; the impregnation device comprises an execution assembly and further comprises a frame assembly located outside the execution assembly, impregnation liquid is prepared through centrifugal force, meanwhile, the impregnation liquid is discharged to the non-woven fabric through the flow guide effect of a vortex partition plate, and therefore the non-woven fabric is subjected to impregnation treatment, the impregnated non-woven fabric is dried through an electric heating roller, and the non-woven fabric is dried through the frame assembly. After the winding device is rotated, the impregnation liqui
