Title: Production of artificial filaments by wet spinning
IPC: D01D5/06
Filed: 1960-12-01
Abstract: 975,172. Wet spinning artificial filaments- CELANESE CORPORATION OF AMERICADec. 1, 1960 [Dec. 11, 1959], No. 29385/64- Divided out of 975,171. Heading B5B. A wet spinning process is started by covering the spinneret face with a solvent for the filament-forming material, extruding through the spinneret just sufficient spinning solution to cover the exit ends of the spinneret orifices with the solution and form a crown of the solution, then replacing the solvent, before it can dissolve the crown, with coagulant and thereafter pulling away the coagulated crown while supplying spinning solution to the spinneret to continue extrusion of filaments drawn away with the coagulated crown. The extrusion of spinning solution may be started before the spinneret is fixed to the supply pipe feeding it during spinning, extrusion from the open pipe and taking place into a solvent for the filamentforming material to form a globule of spinning solution at the end of the pipe, and the pipe end may then be wiped clean and the spinneret, dressed with filter cloths and wet with solvent, may be secured to the pipe end and the crown of spinning solution formed thereon. The crown of spinning solution may be coagulated and filament production initiated with the aid of a strongly precipitant liquid coagulant by the process described in Specification 975,171. The process may be used in the wet spinning of solutions of cellulose esters, particularly cellulose acetate having an acetyl value of at least about 59% by weight calculated as combined acetic acid (cellulose triacetate). The process may be carried out using a conventional apparatus in which spinning solution is extruded upwardly through a spinneret into a spinning pot through which coagulant is circulated during normal spinning and from which the filaments formed are taken through a vertical column filled with the coagulant. The spinning solution may be a 21% solution of cellulose triacetate in a 90/10 methylene chloride/methanol mixture.
