Definitions

  • This invention has reference to improvements in the precipitation of cellulose from its solutions by means of which a very strong and superior grade of an artificial fibrous material may be produced.
  • aqueous or acidified aqueous salt solutions have been employed as a rule.
  • a precipitating bath in which the Water is replaced by methanol presents great advantages over the precipitating baths heretofore known.
  • aprecipitating bath consisting of a solution of magnesium chloride or magnesium-sulphate in methanol and an inorganic acid is particularly suitable. It is also possible within the scope of this invention to employ a mixture of methanol and aninorganic acid or merely a solution of an inorganic salt in methanol.
