Description
Patented Nov. 28, 1933 1,937,110 vl'soosE SOLUTION. Richard Els sner, Johnson City, Tenn; assignor to American Glanzstoff Corporation,
New
York, N. Y., a corporation of Delaware N 0 Drawing.
Application July 21, 1931 Serial No. 552,192
3 Claims.
My present invention has to do with a new method for producing a filament of viscose possessing light-reflecting properties differing from those ordinarily produced.
One object of this invention is to incorporate with the solution a salt which will produce such an effect on the light-reflecting qualities of the formed filaments that they will appear to be of a duller lustre than ordinary artificial filaments.
Another object of this invention is to produce a viscose solution which will result in filaments possessing a sheen or lustre resembling that of real silk.
Other objects will become apparent from a study of the following specification.
When cellulose is impregnated with a mercerizing solution of caustic soda, and carbon bisulphide is then added, a water-soluble sodium salt of cellulose xanthogenic acid is produced. This salt is called Viscose and may be readily decomposed with the formation of gelatinized cellulose.
Theoretically, during the viscose reaction, sodium cellulose xanthogenate is formed as follows:
of fine filaments into a setting bath containing,
usually, acids and sulphates.
My new invention has to do with a viscose spinning solution which contains certain amounts of salts of xanthogenic acid or derivatives of this acid, or homologues of the same.
The general type formula for this acid may be indicated by the formula: I
For example, the calcium salt of dithio-carbonic acid-o-isobutyl ester of the general formu- .S-Ca--S o=s e o ooiH, moio I g 5 may be formed during the mercerization and it may be added directly to the solution prior to I spinning.
As a second example, I may form a salt which might be termed the dithio-carbonic acid starch ester, possessing the general formula:
SNa
O(Starch) Besides calcium salts, those of barium and strontium may also be used.
These compounds thus formed should be soluble in the viscose solution.
They are decomposed during the spinning process in the same manner as, the cellulose xanthate. Depending upon the. metal M which'has been used, soluble or insoluble metallic salts are formed Q in the filaments, film, etc.
The nature of the radical R controls the fact a 7 as to whether or not organic compounds are formed in the filament, film, etc., which upon evaporation, might produce bubbles. These bub-I bles, if so produced, would have the effect of reflecting the light in sucha wayas to produce duller lustre.
Having now set forth my by the patent statutes,'what I desire to claim is:
1. A viscose solution containing asalt of dithiocarbonic acid-o-isobutyl ester.
2. A viscose solution containing a calcium salt of dithio-carbonic acid-o-isobutyl ester. I
3. A viscose solution containing a barium saltof dithio-carbonic acid-o-isobutyl ester.
RICHARD ELSSNER.
