<p>PROBLEM TO BE SOLVED: To obtain a nonwoven fabric for extrusion lamination capable of being directly extruded and laminated onto a film and excellent in interlaminar strength and a film-nonwoven fabric composite using the nonwoven fabric and readily producible and processable and further the film-nonwoven composite excellent in strength, touch feeling, water resistance and moisture permeability and suitable as sanitary materials. SOLUTION: This nonwoven fabric for extrusion lamination has a mixed resin comprising (A) a polyolefin and at least one kind selected from (B1) a modified polyolefin modified with an unsaturated carboxylic acid or its derivative, (B2) an ethylenic copolymer containing a comonomer unit having a polar group and (B3) a modified thermoplastic elastomer prepared by modifying a thermoplastic elastomer with an unsaturated carboxylic acid or its derivative on the outer surfaces of filaments constituting the nonwoven fabric. The film- nonwoven fabric composite suitable as the sanitary materials is obtained by integrating the nonwoven fabric with a thermoplastic resin film, providing the composite and using an elastomer having moisture permeability as the film.</p> |
