ABSTRACT:
A method for spinning a cellulose acetate fiber having a low degree of substitution per anhydroglucose unit (DS/AGU) of the cellulose acetate is provided. The addition of 5 to 40 weight percent water to cellulose acetate(CA)/acetone spinning solutions (dopes) will produce dopes that will allow fibers to be solvent spun using CA with a DS/AGU from 1.9 to 2.2.
