Abstract:
The present invention is a wet type nonwoven fabric that includes two or more kinds of fibers, wherein the wet type nonwoven fabric includes a short fiber A that is constituted of a fiber-forming thermoplastic polymer and has a fiber diameter D of from 100 to 1000 nm and the ratio of a fiber length L to the fiber diameter D, L/D, in the range of from 100 to 2500 in from 4 to 50% by weight relative to the total weight of the nonwoven fabric, and a binder fiber B that has a single fiber fineness of 0.1 dtex or less in from 10 to 50% by weight relative to the total weight of the nonwoven fabric.
