られていない。Absorbent articles such as paper diapers that are widely used at present are formed of three layers of a surface material, an absorbent material, and a back material from the side that comes into contact with the skin when worn. In addition to strength and flexibility, the surface material is water permeable to quickly transfer the liquid to be absorbed to the absorbent, prevents the liquid that is absorbed to absorb it from returning to the skin, and has a dry feel to the skin. In order to achieve such an object, US Pat. No. 369526 is required.
Nonwoven fabrics composed of hydrophobic fibers are often used as proposed in No. 9, 4041951 and No. 4391869.
If a non-woven fabric is made to have a strong hydrophobicity, the dry touch property of the surface material using this will be improved, but it will lead to a decrease in water permeability. There are attempts to make it possible, but satisfactory performance has not been obtained.

There is. In response to such a demand, in the surface material using the non-woven fabric in which the surface activity is adhered to the above-mentioned hydrophobic fiber, when the liquid is absorbed once or twice, the surface active agent is washed out and the water permeability is rapidly lowered. There are drawbacks. An object of the present invention is to eliminate the drawbacks of conventional surface materials and to provide a surface material for absorbent articles having both appropriate water permeability and dry touch property even after absorbing liquid repeatedly.
