Abstract
Fibers are modified by applying a solution of a low substituted cellulose ether having a molar degree of substitution with alkyl and/or hydroxyalkyl groups in the range of 0.05 to 1.0 in an aqueous alkali solution to fibers, and causing the solution borne on fibers to coagulate. The method achieves satisfactory fiber modifications with respect to antistatic property, moisture absorption and shrink resistance without a cumbersome step of dissolution while ensuring safety.
