Abstract

267,187. Tennant, W. J., (Rousset, J.). Nov. 11, 1925. Cellulose acetate, cellulose nitrate, and other cellulose derivatives, processes for making filaments from. - Hollow artificial filaments are made by dry spinning a normal solution of a cellulose ester &c. by extruding the solution into air or other gaseous medium at a temperature which is substantially higher than the boiling point of the solvent employed in the solution, the filaments at the moment of extrusion being subjected to an active superficial evaporation by maintaining a comparatively high rate of flow of the gaseous medium. With cellulose acetateacetone solutions, a suitable temperature range is 90-155‹ C., although the best results are obtained between 100-120‹ C.; in the case of nitrocellulose solutions in alcohol-ether, satisfactory results are obtained at 90-100‹ C. Specifications 189,973 and 248,696 are referred to.
