EMILE BRONNERT, OF NIEDERMORSCHWEILER, NEAR MULHAUSEN, GERMANY, ASSIGNOB TO THE FIRM OF VEREINIGIE GLANZSTOFF-FABRIKEN A.-G., F
ELBEBF'ELID, GERMAN Y.
IROCESS FOR THE PRODUCTION OF THREADS, FILMS, 0R PLATES.
l l'o Drawing.
To all whom it may concern:
Be it known that I, EMILE BRONNERT, a 'subject of the Emperor of Germany, residing at Niedermorschweiler, near Miilhausen, a Alsace-Lorraine, Germany, have invented certain ne and useful Improvements in Processes for the Production of Threads, Films, or Plates; and I.do hereby declare the following to be a full, clear, and exact 1o description of the invention.
For producing formed articles, such as threads, films or plates, by precipitating the same from viscose .solutions it has been found to be advantageous to employ such 16 acids, which form soluble or even deliquescent salts with the soda of the viscose; these acids being employed either alone or preferably together with a salt (for .instance sodium salt) of the corresponding an acid. Suitable cheap acids of this kind are the non-volatile aliphatic hydroxy acids,
such as lactic acid, glycolic acid citric acid,
tartaric acid. The precipitation will practically be performed rather at a Warm ternperature (for instance a temperature of 20-60 C. in the precipitating bath has produced good results, but the higher the temperature the more the coagulation together with decomposition takes place). For example a mixture of one liter of saturated solution of lactate of soda with for instance 1&0 grams of lactic acid added thereto makes at 60 C. an excellent precipitating Specification 01' Letters Patent.
Application filed April 9, 1813. Serial No. 759,932.
Patented July '7, 1914.
bath for spinning artificial threads from a viscose solution for example into the well known centrifugal boxes with a satisfactory velocity.
The further treatment of the precipitated threads or the like may be carried out ac cording to known processes. The employ- 4Q ment of the said nonvolatile acids of the fatty acid series (being of organic nature) together with their salts, instead of sulfuric Or formic acid, is particularly advanta eous because they are not volatile, and ono harm either to the gelatinous thread freshly formed or to the metals of which the spinning bones are made, or to the work people.
What I claim is:
In" producing threads, films or plates or the like from viscose solution, the process which consists in conducting the viscose solution through a heated precipitating bath consisting of a solution of a salt of nonvolatile aliphatic oxyacids such .as lactic, glycolic, citric, tartaric acid together with a sufiicient quantity-may 15-20% of the same free acid. 2
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
EMILE BRQNNERT.
