PURPOSE:To obtain a bulky nonwoven fabric for sanitary materials excellent in dry touch properties and feel without repetitive deteriorating wet back and water absorption rate. CONSTITUTION:This nonwoven fabric for sanitary materials is obtained by laminating and integrating a highly shrinkable fiber sheet on a low-shrinkable or a nonshrinkable nonwoven fabric and subjecting the resultant laminate to shrinking treatment under conditions so as to enable the sufficient shrinkage of the fiber sheet. The nonwoven fabric has 2-20 wrinkles 0.2-3mm deep per cm on at least one side, >=15cm<3> apparent specific volume, <=0.2% initial wet back and <=2.3sec initial absorption rate. |
