Definitions

  • washing processes may have proved useful for certain kinds of artificial silk (such as of copper oxide a'mmonial), where the chemicals adhering to the fibre are complete-- ly soluble in water.
  • This is, however, different with viscose silk, especially such of unripe viscose matter (unripe alkali-cellulose);
  • considerable quantities of bisulphide of carbon are produced in the decom osition of the viscose matter, which bisulphlde of carbon is insoluble in water.
  • This bisulphide of carbon repels the washing water, thereby preventing a favourable washing effect.
  • considerable time is reqllliired in this case, or washing water of a big ertemperature must be used, the application of which,
  • the present invention relates to a process for removing the bisulphide the fibre in the s carbon, from ortest possible way and Application filed March 26, 1925. Serial No. 18,605.
  • a process for treating freshly spun unripened viscose silk on spools consisting in subjecting said silk before the usual washing to a yacuum of sufficient strength to rapidly and completely remove the carbon disulpfioiide resulting from the spinning, from the name .tothis specificatiom' '13s.
