Definitions

  • Thisinvention concerns improvements in orrelating to processes for the manufacture of artificial textile fibers.
  • the process may be effected with the addition of aluminium salts and/or tin salts and/or formaldehyde with ortwithout sodium salts to the acid coagulating ba h.
  • Example A An aqueous solution of sulphuric acid and sodium sulphate is made, the proportions being such that the bath contains 140 cubic centimetres of 66 B. sulphuric acid and 400 grammesof sodium sulphate for each litre of the'bath.
  • aluminium salts are added, preferably aluminium sulphate or potash alum. It is also advantageous to add small quantities of tin salts, for example tin acetate.
  • Example B ence of the sodium chloridin the bath assists the action of the aluminium salts in making filaments insoluble.
  • the first bath is likewise preferable and the amount of sulphuric acidemployed can be gradually reduced to of the amountindicated above according to the higher or lower percentage of viscose added to the casein solution. 'I'he higher the percentage of viscose, the lower can be the amount of acld'in the coagulating bath. Also, the bath temperature may be slightly lower.
