Definitions

  • This invention relates to processes or making high-grade viscose products, especially for spinning purposes, for instance for the manufacture of fine-threaded viscose silk.
  • ceratin containing substances such as for instance wool
  • certain dissolving agents such as for instance diluted sulphuric acid
  • metal salts such as chromic salts
  • waste-products such as leather which had been treated by chromium compounds.
  • the following may serve as an example for carrying out my new process of making high-grade viscose products.
  • Example 200 g. of leather treated by chromium compounds are dissolved in about 1 liter of a 10% sulphuric acid at moderate heat and a. concentrated solution of sodium sulphate and sulphuric acid is added to this solution, so that the solution made for the spinning bath will contain about 100200 g. of ceratin contain ing constituents or their waste-products, about 130l50 g. of sodium sulphate and 1301el0 of sulphuric acid per liter.
  • viscose threads 01' 1 denier and less may be made according to the process forming part of my present invention.
  • the step of extruding filaments and the like of viscose material into a setting bath which consists of an acidic bath containing a member from the group comprising gluten and ceratin.
