Abstract
In the composition and method of treatment of cellulose filaments, the emulsion that is applied to the filaments after spinning, but before drying, includes, in combination, a cone oil, a surface active agent, such as of alkyl polyamine derivatives or polyoxyethylene alkyl ether type agent, a positive ion water solution for alkyl polyamine derivative, polyoxyethylene alkyl ether type surface active agent, urea resin, a resinfication catalyzer, and water, and after treatment of the filaments with said emulsion, subsequent to their spinning, said treated filaments then being dried in a tunnel type dryer, in a high frequency heating type dryer, to provide filaments having reduced shrinkage, and lower-swelling characteristics during application and usage.
