Abstract

311,763. Aceta Ges. May 16, 1928, [Convention date]. Grant of Patent opposed. Apparatus for making filaments. - The lack of thermal homogeneity and consequent variation of viscosity in solutions emerging from the spinning nozzle in the dry spinning process, is obviated by guiding the solution in symmetrically disposed streams and in as thin layers as possible along surfaces of a body of high heat capacity placed directly above the nozzle. By making the mass of such a body sufficiently large compared with the volume of solution in contact therewith a homogeneous solution giving a thread of uniform titre is obtained. In the construction shown in Figs. 1 and 2, a comparatively thin hollow cylinder a, attached to the spinning nozzle at f is almost filled by a massive coaxial cylinder b leaving a narrow passage for the flow of solution. Perforations h as shown, or peripheral grooves in the direction of flow in the cylinder b may facilitate the flow. The heat capacity of the cylinder a is increased by external fins g. Bodies of any desired form may be used in place of cylinders and there may be partial contact to minimize temperature inequalities. Or the body may be a single piece with symmetrically disposed passage ways for the flow of solution.
