Abstract

265,577. Syntheta Akt.-Ges. Feb. 4, 1926, [Convention date]. Apparatus f o r making filaments. - The solvent is recovered in spinning artificial silk by extruding the threads i n t o a chamber heated to a temperature above the boiling point of the solvent and enclosing a heated atmosphere consisting only of the vapours of the solvent evaporated from the threads. As shown, the threads are projected from nozzles b arranged in the roof of a chamber a heated by steam pipes, not shown, and the threads are collected on spools. The concentration of the solvent in the atmosphere of the chamber, is maintained constant by withdrawing vapour from the latter and passing it through a condenser c, uncondensed vapour being returned to the chamber; the withdrawal and return of the vapour is effected through perforated pipes b<1>, b<2>, connected to a pump. The condenser is arranged as a byepass in the circulating system, the proportion of vapours passed to the condenser being determined by valves in the piping.
