Abstract
A method of producing a fine fiber, including treating a cellulose raw material with an enzyme; and fibrillating the treated cellulose raw material; treating with the enzyme under a condition where at least a ratio of endo-glucanase activity to cellobiohydrolase activity that is 0.06 or greater. The cellulose raw material may be a plant fiber. The method 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.
