UNITED s'rATss PATENT OFFICE;
PBoOCESS F PgggggNG 4 'Oskar Huppert, Chicago, 111., assignor to The Glidden Company, Cleveland, Ohio, at corporation of Ohio No Drawing. Original application May 13, 1940,
Serial N 334,920. Divided and this application March 10, 1941, Serial No. 382,577
3Claims.
The present invention relates to the production of artificial fibers from soya protein, such as artificial wool and the like.
The present application is a division of application Serial No. 334,920, filed May 13, 1940.
In the manufacture of artificial protein fibers, a spinning solution of the protein is extruded through spinnerets into a coagulating bath and the fibers are then hardened. After hardening the fibers are'washed, subjected to an aftertreatment, and may be variously treated to produce the finished fiber.
In the case of casein, for example, the fibers, after hardening, do not stick together and may be subjected to washing and the after-treatment without any particular difiiculty. In the case of soya protein fibers, however, the individual fibers or filaments after hardening are sticky and ad- .herent with the result that they stick together to form a coherent mass, thereby preventing successful after-treatment, carding and the like.
It is,- therefore, an object of the present invention to overcome the aforementioned-sticking of the hardened soya protein fiber.
It is a further object of the present invention to treat the hardened films before washing or other treatments to overcome the aforementioned sticking. a
The invention is applicable to any fiber prepared from soya protein. The fiber may be spun from suitable solutions of either hydrolyzed or unhydrolyzed protein. Th spinning solution may also comprise in whole or in part a soya protein disulfide'prepared in accordance with United States Patent No. 2,112,210. Such a protein disulfideis prepared by treating a soya protein hydrolysate with carbon disulfide at a hydroxyl ion concentration which corresponds at most to that ofa solution of calcium hydroxide and then oxidizing the thus sulfurized protein to form the disulfi de. The objects of the present invention may be accomplished by subjecting the hardened fiber,
before washing, to the action of nitrous acid. The
action of the nitrous acid is such that the fibers 'lose their stickiness and may thereafter be washed, subjected to an aftertreatment, and otherwis successfully handled. It is surprising that the strength, elasticity, and flexibility of the fibers are not diminished by the treatment with nitrous acid. on the contrary, they become more resistant to boiling water and take dyes more easily. By this treatment the fibers become hydrophobic permanently waterproof and fast to washing and dry cleaning.
The treatment with nitrous acid maybe effected in any suitable way. The fibers maybe immersed in a'solution of nitrous acid for a short time. Preferably when the fibers are acid, such 5 as when-they are coagulated in an acid bath, they may be immersed in a solution of sodium nitrite or other suitable nitrous acid forming substance.
The following examples are illustrative.
Example I grams of sodium hydroxide. This solution is allowed to ripen one or two days and the spinning solution soobtained, after being freed of air, is
spun into a coagulating bath of a combination of 25% sulfuric acid and 15% sodium sulfate. The
fibers are then treated in a hardening bath containing 5% formaldehyde and 8% sodium chlo- 20 ride. The acid containing fibers, before washing are then treated for 5 minutes in a 2% solution.
- of sodium nitrite, after which they are washed.
, No sticking. difiiculty is encountered during the washing operation and the fibers may be sub- .iected to an after-treatment and other operations without encountering sticking difiiculties.
' Example II then bubbled into the solution at 60? C. with vigorous stirringfor an hour. The solution is allowed to cool to room temperature while agitat- 40 ing. The spinning of 'the. fibers, coagulation,
hardening and nitrous acid treatment is thereafter the same as in Example I.
It will be understood that the detailed procedures described are capable of variation and modification without departing from the spirit and scope of the invention defined in the appended claims. I claim:
'1. The processor preparing artificial fibers 59 comprising spinning into a coagulating bath to form fibers a solution containing soya protein disulfide prepared by treating soya protein hydrolysate with carbon disuliide at a hydroxyl ion con-. centration which at mostcorresponds to that of a solution of calcium hydroxide and oxidizing the 300 grams of hydrolyzed soya protein are dissolved in 1560 cc. of water with the acid of 15 thus suliurized protein to produce the disulfide,
resulting sulfurized protein to form the disulflde.
3. The process which comprises treating with nitrous acid a disulfide protein fiber spun from a solution of a protein disulfid resulting .Irom treatment of protein with carbon disuiflde and oxidation of the resulting sulfurized protein to form the disulfide.
