| abstract | Threads are produced by extruding a solution of an acrylonitrile polymer in an organic solvent which is soluble in carbon tetrachloride into a coagulant bath consisting of or containing carbon tetrachloride. The polymer may be a homopolymer of acrylonitrile or a copolymer thereof with another polymerizable compound, e.g. styrene, methyl acrylate or vinyl acetate. The solvent may be dimethyl formamide and the concentration of polymer in the solution may be between 15 and 20 per cent. The coagulant bath may be at a temperature between 40 DEG and 50 DEG C. In an example a copolymer of vinyl acetate and acrylonitrile dissolved in dimethyl formamide is extruded into a bath of carbon tetrachloride at 48 DEG C. The thread is taken from the coagulating bath at 17 metres/minute and is stretched by passage through ethanol at 60 DEG C. on to a godet with a peripheral speed of 74 metres per minute. Specifications 459,596, 461,675, 583,939, 584,548 and U.S.A. Specification 2,467,553 are referred to. |
