Abstract:
Provided are: a nonwoven fabric having good sucking properties and wash durability; and a method for producing a nonwoven fabric. The nonwoven fabric is provided with multiple fiber bundles each having regions adhesive to a binder (i.e., binder-adhesive regions), wherein, when observed on a cross section randomly selected from the binder-adhesive regions, multiple single fibers are constrained by the binder so as to be integrated together, and the total number of single fibers in the fiber bundles is a value that satisfies the formulae: Nu/Nc > 1.10 and Nb/Nc > 1.10 wherein Nu represents the total number of fibers in upper layer bundles, Nb represents the total number of fibers in lower layer bundles, and Nc represents the total number of fibers in intermediate layer bundles.
