Abstract
A sanitary napkin for women includes a permeable inner sheet, which comes into contact with the skin of a wearer to thus allow secretions to pass therethrough, an outer sheet fused to the inner sheet, and an absorption pad disposed between the inner sheet and the outer sheet to absorb the secretions passed through the inner sheet, the outer sheet being a nanolaminate film composed of a nanomembrane formed by electrospinning a polymer solution and a strength-reinforcing nonwoven fabric laminated on one side of the nanomembrane.
