Definitions

  • Known spinning baths for making artificial silk and other artificial textile fibres from viscose generally consist in a mineralacid solution, with or without the addition I Application filed June 30, 1824. Serial No. 723,865.
  • nitric acid A very small proportion of mtrlc acid in the bath suffices to produce a good efiect, even an addition of 0.1 per cent of nitric acidshowing its influence. Under certain conditions dependent upon the degree of maturity and composition of the viscose and also on the maturity of the soda cellulose used, the proportion of added nitric acid may be increased, for instance it may amount to 5 per cent. 1 I
