摘要 |
Provided is a high strength wet-laid nonwoven fabric having strength, i.e., tensile strength, tear strength and interlayer peeling strength, similar to those of a filament nonwoven fabric, and a uniformity similar to that of a conventional wet-laid nonwoven fabric. This nonwoven fabric is made of a fiber having a fiber diameter of from 7 mu m to 25 mu m and a ratio L/D of from 0.8 x 10<3> to 2.0 x 10<3> and is produced by entangling the fibers in a sheet made by a paper making machine by using a columnar water stream. |
