PROBLEM TO BE SOLVED: To provide a method for inexpensively and stably manufacturing a skin material preventing bleeding of a foam urethane resin to the skin material and not imparting the texture of nonwoven fabric without using a fluorine-based oil-repelling agent. ! SOLUTION: The method for manufacturing a nonwoven fabric processed with a non-fluororesin waterproofing agent includes: applying an aqueous coating material comprising at least a non-fluororesin waterproofing agent and a foaming agent and being adjusted to have an expansion ratio of 6-11.5 times and a viscosity of 6,000-14,000 mPa s in an amount of 8.5-22 g/m2 based on a nonvolatile content to one surface of a nonwoven fabric composed of a chemical fiber and having a basis weight of 130-200 g/m2, a thickness of 1.5-2.5 mm and an apparent density of 0.08-0.12 g/cm3; and drying the coating material at a temperature of 95-155°C. !
