METHOD FOR PRODUCING FINE FIBER, FINE FIBER, NON-WOVEN FABRIC, AND FINE FIBROUS CELLULOSE

摘要

The present invention relates to a method of producing a fine fiber, the method comprising the steps of: treating a cellulose raw material with an enzyme; and fibrillating the treated cellulose raw material; the step of treating with the enzyme comprising treating under a condition where at least a ratio of EG activity to CBHI activity is 0.06 or greater. Preferably, the cellulose raw material is selected from plant fibers. The present invention can provide a method of producing a fine fiber that efficiently produces a fine fiber from a cellulose raw material at low cost and with a low environmental burden; a fine fiber; and a non-woven fabric.
