Definitions

  • the invention relates to an improvement in the process of spinning viscose artificial silk, filaments comprising threads, staple fibres, bands and the like and especially to a method for preventing the obstruction of the spinning nozzles, which is caused by the slow clogging of the orifices during spinning.
  • the said obstruction is especially serious when using a spinning bath containing zinc sulphate.
  • invention is the addition of compounds which are stable in acid as well as in alkaline liquids. Still another object is not to use additions causing foam formation in concentrating the spinning bath by evaporation.
  • R represents an aromatic radical containing no more than 6 carbon atoms
  • R represents a substituent selected from a class consisting of hydrogen, aliphatic hydrocarbon groups containing no more than 2 carbon atoms and aryl groups containing no more than 6 carbon atoms
  • X represents a substituent selected from a group consisting of OH and a monovalent acid radical.
  • the pyridinium nucleus can be replaced by a homolog or derivative of yridinium.
  • 67, 656 (1934); 68, 1351 (1935) be prepared from pyridinium or a homolog or derivative of'pyridi-nium, an alkali halide which may or may not be substituted and an aldehyde.
  • Pyridinium halides or other pyridinium salts with a'monovalent acid radical or compounds from which such pyridinium salts can be formed under the reaction circumstances can also be used as a starting material.
  • the compounds to be used according to the invention can also be prepared from other starting materials, e. g. from styrene, bromohydrine or from homologs or derivatives of pyridinium.
  • the indicated compounds are generally spea ing not only stable in diluted acids, but also in cold diluted alkaline liquids and they can therefore 1 be added to the viscose as well as to the spinning the surface-tension of aqueous solutions and are a bath.
  • the compounds not being surface-active there is no foam formation when concentrating the spinning bath in the regeneration thereof.
  • Example I N(a-furyl-2' hydroxy-Z phenyl-l' ethyl) -1 pyridiniumbromide.
  • An equivalent amount of furfural is added to a solution of benzylpyridiniumbromide in ethanol. After the addition of 10 11.
  • sodium lye the reaction mixture is deposited during 5 days at 0 C.
  • the separated product is washed with alcohol and treated with decolorizing carbon and then recrystallized from waterof C.
  • the product melts at 207 C. under decomposition.
  • This compound is prepared from f-urfural and.
  • allylpyridiniumbromide not sharply defined.
  • the decomposition begins at 140 C.
  • the 'melting point is After spinning. for about 8 hours the obstruction of the orifices amounts of sodium sulphate and sulphuric acid and 50g. 01'- zinc-sulphate per litre.
  • Example IV N-( phenyl- 2 hydroxy-2' vinyl-1' ethyl) -1 pyridinium bromide was prepared from allylpyridiniumbromideand benzaidenyde. 0.1% of this com' pound was added to viscose and spinning took place in a bath with normal amounts 'of sodium sulphate and sulphuric acid. and 50 g. of zinc sulphate per litre.
  • R represents an aromatic radical containing no more than 6 carbon atoms
  • R represents a substituent selected from a class consisting of hydrogen, aliphatic hydrocarbon groups containing no more than 2 carbon atoms and aryl groups containing no more than 6 carbon atoms
  • X represents a substituent selected from a group consisting of OH and a monovalent acid radical.
