<p>The present invention provides fibril based fibers for use in filters and artificial leather, an industrially advantageous method of manufacturing such fibril based fibers, and a spinning nozzle. The fibril based fibers of the invention are composed of a high molecular polymer having a capability of forming at least one kind of film, and are structured such that fibrillated fibers having a diameter of 10 νm or less branch from a main fiber having a width of 0.1 to 500 νm and a length of 10 νm to 10 cm.</p> |
