| titleOfInvention | Improved process for the production of threads, films, bands and like products from viscose |
| abstract | Artificial threads, films and like products are produced by extruding viscose into a coagulating bath containing sulphuric acid, sodium sulphate, at least 0.5 per cent of zinc sulphate, a small proportion of a cation-active substance which is a quaternary ammonium salt derivative of pyridine (or a homologue thereof) in which an aliphatic chain containing more than 6 carbon atoms is attached to the pyridine nitrogen atom, and a small proportion of a second cation-active substance which is the reaction product of ethylene oxide and the amide of a fatty acid containing not less than 12 carbon atoms in the molecule, said amide also containing amino groups. In an example a viscose containing 7.3 per cent by weight of cellulose and 6.8 per cent by weight of caustic soda and having an ammonium chloride number of 11.5 is extruded into a spin bath at 70 DEG C. containing 7.4 per cent by weight of sulphuric acid, 16.9 per cent by weight of sodium sulphate, 3.5 per cent by weight of zinc sulphate, 10 mg. per kg. of "Antarox G-100" (a reaction product of ethylene oxide and an amide formed by reacting sperm oil with such an excess of a polyamine that only some of the amino groups are converted into amido groups, 15-19 mols. of ethylene oxide being reacted per mol. of the amide), and 25 mg. per kg. of lauryl pyridinium chloride. Dodecyl pyridinium hydroxide, chloride, bromide or iodide, hexadecyl pyridinium iodide, octadecyl pyridinium bromide or lauryl pyridinium sulphate may be used instead of lauryl pyridinium chloride. The addition of the pyridine derivative to the spin bath as well as the "Antarox G-100" enables the concentration of the latter required for the prevention of deposits in the spin bath to be reduced. Sepcifications 469,817 and 478,774, [both in Group IV], are referred to. |
