Description
Patented May 12, 1936 UNITED STATES PATENT OFFICE MANUFACTURE OF ARTIFICIAL SILK No Drawing. Application October 4, 1932, Serial No. 636,180
4 Claims.
My present invention has to do with a new and novel method for producing artificial cellulosic products with a low lustre.
More especially, my present invention concerns 5 a new method for producing artificial filaments which possess the desirable low lustre of real silk.
One object of the present invention is to provide a novel method for producing a filament or thread of artificial silk which has greater opacity and covering power, and which possesses a low or dull lustre.
Other objects will become apparent from a study of the following specification and claims.
In the manufacture of artificial filaments, a cellulosic solution is prepared (cuprammonium, viscose, nitrocellulose or organic derivatives of cellulose), and spun or extruded into a medium which tends to harden the filaments thus formed. My present invention has to do with a new and novel mixture or compound, to be added to the spinning solution before the filaments are formed, and which remains in the filaments during the after treatment thereof. The presence of this substance in the filaments gives them the greater opacity and covering power desired and renders them lustreless.
I prepare an emulsion which I add to the spinning solution prior to the extrusion of the filaments. This emulsion is thoroughly mixed with the solution, and is composed of:
Casein One part Nitrocellulose-lacquer Two parts Of this emulsion I prefer to add about 15% to the cuprammonium cellulose or viscose solutions, said percentage being based upon the cellulose content of said solutions.
Having now set forth my invention as required by the patent statutes, what I desire to claim is:
1. A cellulosic spinning solution for the manufacture of soft-lustre products comprising a substance selected from the group consisting of viscose and cuprammonium cellulose together with casein and a nitrocellulose lacquer.
2. A soft-lustre viscose filament containing a small amount of casein and of a nitrocellulose lacquer.
3. A soft-lustre cuprammonium cellulose filament containing a small amount of casein and of a nitrocellulose lacquer.
4. A cellulosic spinning solution for the manu facture of soft-lustre products comprising a substance selected from the group consisting of viscose and cuprammonium cellulose together with about 15 per cent of an emulsion consisting of one part of casein and two parts of a nitrocellulose lacquer, said percentage of emulsion being based upon the cellulose content of said substance.
