Abstract
Small amounts of acridine dyestuffs are added to concentrated protein spinning solutions, particularly those to be used in dry spinning processes. The acridine dyestuffs prevent putrefaction of the protein solutions and formation of gas bubbles therein during storage or treatment for spinning. The spinning operation is facilitated since stronger threads are produced and there are less breakages. In examples, spinning solutions comprise 24-26 per cent of casein, 0.5 per cent of oleic acid, and 0.005-0.01 per cent of an acridine dyestuff, dispersed in caustic soda solution of sufficient concentration to give a solution with a pH value of 9.2. The solutions may be used for spinning artificial threads at 40 DEG C. even three or four days after the original preparation. Dyestuffs specified are: 2-ethoxy-6, 9-diamino-acridinium lactate, 10 - methyl - 3 - amino - 9 - (4 - amino - phenyl) - acridinium hydrochloride, 10 - methyl - 3, 6 - diamino - acridinium hydrochloride and 2,8-diamino-acridinium hydrochloride.
