Elastic Nonwoven Fabric

Abstract

The object of the present invention is to improve the elasticity of a nonwoven fabric manufactured by the spunbonding method. To attain the object, the present invention provides a nonwoven fabric manufactured by the spunbonding method, wherein a lot of holes are formed in the nonwoven fabric by the needle punching method, to give said nonwoven fabric elasticity. Synthetic resin may be impregnated into the nonwoven fabric.

1 . An elastic nonwoven fabric made of a nonwoven fabric manufactured by a spunbonding method, wherein a multiplicity of holes are formed in said nonwoven fabric by a needle punching method, and synthetic resin is impregnated into said nonwoven fabric. 
   
   
       2 . (canceled) 
   
   
       3 . An elastic nonwoven fabric in accordance with  claim 1  wherein said synthetic resin comprises a thermoplastic resin. 
   
   
       4 . An interior material for an automotive vehicle, said material comprising a nonwoven fabric in accordance with  claim 1 , as a surface layer material, and a base material having a surface to which said elastic nonwoven fabric is attached as a surface layer, then being molded into a prescribed shape. 
   
   
       5 . An interior material for an automotive vehicle, said material comprising a nonwoven fabric in accordance with  claim 2 , as a surface layer material, and a base material having a surface to which said elastic nonwoven fabric is attached as a surface layer, then being molded into a prescribed shape. 
   
   
       6 . An interior material for an automotive vehicle, said material comprising a nonwoven fabric in accordance with  claim 3 , as a surface layer material, and a base material having a surface to which said elastic nonwoven fabric is attached as a surface layer, then being molded into a prescribed shape. 
   
   
       7 . An elastic nonwoven fabric in accordance with  claim 1 , wherein said holes range in number between substantially 10/cm 2  and 100/cm 2 . 
   
   
       8 . An elastic nonwoven fabric in accordance with  claim 1  having a weight within the range of substantially 30 g/m 2  to 60 g/m 2 . 
   
   
       9 . an elastic nonwoven fabric in accordance with  claim 1 , wherein each of said holes has a diameter within the range of 0.1 mm to 2.4 mm.
