Abstract: 1,032,991. Wet-spinning polyacrylonitrile. COURTAULDS Ltd. Dec. 4, 1962 [Dec. 5, 1961], No. 43434/61. Addition to 940,020. Heading B5B. A solution of polyacrylonitrile in a mixture of dimethyl formamide and an aromatic hydrocarbon, which solution has been prepared according to claims 1, 4 and 5 of the parent Specification, is extruded into a spin-bath comprising a mixture of an aromatic hydrocarbon and dimethyl formamide in which mixture the hydrocarbon/D.M.F. ratio is maintained at a sufficiently high level to cause the separating out of the polyacrylonitrile in the form of filaments, the liquor is contacted with a sufficiently high proportion of water to cause the liquor to divide into an aqueous phase containing D.M.F. and not more than 1% of the hydrocarbon, and the D.M.F. is recovered from the aqueous phase by distilling off the water therefrom. The liquor may be passed from the bottom to the top of a packed column or a series of packed columns in counter-current to water percolating through the column(s) or water may be passed through the coagulating bath simultaneously with the filaments, e.g. by spraying the water in to the bath. The steam formed in the recovery of the D.M.F. from the aqueous phase may be used in the stretching of the filaments in steam. The water condensed from the steam used in the stretching operation may be passed to the spray above the spin bath so that any D.M.F. which may have been extracted from the filaments by the condensed steam in the stretching operation may also be recovered. When equilibrium is established in the spinning operation the spin-bath should comprise at least 8 parts by weight of hydrocarbon to 1 part of dimethyl formamide to maintain adequately the coagulating properties of the spin-bath. The aromatic hydrocarbon in both the spinning solution and the spin-bath may be benzene, toluene, or xylene.
