Abstract
A sanitary napkin comprising a filler including a water-permeable layer of hydrophobic fibers for passing the body fluid therethrough and an absorbing layer underlying the layer for absorbing the fluid, and a water-permeable covering which covers the filler. The napkin is used with the water-permeable layer in contact with the human body. The water permeable layer has outstanding water permeability and functions to prevent reverse flow, permitting the absorbing layer to readily absorb the body fluid while preventing the fluid from returning toward the body. The napkin therefore has an agreeable feel at all times during use without feeling wet or sticky. The cushioning property of the water-permeable layer also gives a comfortable feel.
