Abstract

The heterogeneous acetylation of regenerated cellulose textile articles is carried out using acetic anhydride as the acetylating agents and an alkali metal acetate, especially potassium acetate, as catalyst at 100 DEG -135 DEG C., keeping the acetic anhydride content of the acetylation bath above 95 percent by weight, and also keeping the constituent filaments of the articles at constant length. The process is quick and thus suitable for continuous operation, and avoids mutual cohesion of the filaments as a result of softening or partial solution.
