Description
Patented Oct. 31 1933 UNITED STATES "PATENT OFFICE FILAMENT TREATMENT Franz Hoelkeskamp, Wul Jpcrtal-Barmen, Germany, assignor to American Bemberg Corporation, New York, N. L, a corporation of Delaware '1 Claims. (01. 28-1) My present invention relates to a novel method of producing artificial filaments possessing a dull lustre.
One object of my invention is to provide a new filament having an appearance closely resembling that of natural silk.
Another object is to providea filament which possesses water-repellant qualities.
Other objects will become apparent from a study of the following specification. I
Several attempts have heretofore been made to produce lustreless filaments. According to one proposed method, insoluble metallic oxides are precipitated upon the face of the filament.
The layer of salts thus formed has been found to possess only to a slight degree the necessary adhesion, and, during the subequent wet treatment of the filaments is easily rubbed off of the swollen fibre. Another type of proposal was that the precipitant be formed within the filament itself. According to this method, very finely dispersed powders are suspended in the spinning solution itself. One drawback to this process is the great difiiculty arising through the necessity of using special carriers for the suspension. In some cases the use of suitable carriers is impossible.
According to my invention the disadvantages outlined above are eliminated. In the new process a precipitation of insoluble metallic salts which adhere firmly to the filament is produced. This is accomplished by first precipitating these salts on the filaments, and then pre-.
cipitating' thereon a water repellent hydroxide. As an example, aluminum hydroxide, may be mentioned.
In carrying out my novel method, asoluble metallic hydroxide, for example, barium hydroxide, is deposited by means of a bath on, and partly into, the fibre. The fibre is then treated with a salt solution, the hydroxide of which is especially water repellent. As an example, aluminum sulphate may be employed. It may be found desirable-to add to one or both of the baths used a protective colloid, for example, glue. The following reaction takes. place in the second bath:
Thus it may be seen that the treated fibre contains a close mixture of the delusterizing barium sulphate, and the water repellent aluminum hydroxide. If protective colloids are used the resulting precipitation is rendered even more fine and durable.
Because of the lessening of the swelling action due to the presence of a water repellent precipitant, -I have found that the barium sulphate is enclosed in the filaments and thus rendered diilicult to remove.
As a specific example of my new process, a textile material may be treated with a solution of baryta which contains one gram of Ba(OH)z per litre. Thereafter the textile is treated with a 0.5% aluminum sulphate solution to which 0.025% of glue has been added. Afterwards the material is thoroughly rinsed with clear water in order to remove the excess of aluminum sulphate and the loose barium sulphate, and treated with. a wax-soap emulsion.
As may be easily seen from the above description, my process is limited tono special type of filament. Therefore, Iwish to belimited only by the scope of the appended claims.
I claim:
1. In a process for delustring formed filaments, the-steps of treating them with a solution containing baryta and thereafter with a solution containing aluminum sulphate, then rinsing with water and then treating with a waxsoap emulsion.
2. In a process for delustring formed fila-. ments, the steps of treating them with a solution containing baryta containing approximately one gram of barium hydroxide per litre, and thereafter with a solution containing aluminum sulphate, then rinsing with water.
3. In a process for delustring formed filaments, the steps of treating them with a solution containing baryta containing approximately one gram of barium hydroxide per litre, and thereafter with a solution containing aluminum sulphate, then rinsing with water and then treating with a wax-soap emulsion.
4. In a process for delustring formed filaments, the steps of treating them with a solution containing baryta containing approximately one gram of barium hydroxideper litre, and thereafter with a solution containing aluminum sulphate and a protective colloid, then rinsing with water.
5. In a process for delustring formed filaments, the steps of treating them with a solution containing baryta containing approximately one gram of barium hydroxide per litre, and thereafter with a solution containing aluminum sulphate and a protective colloid, then rinsing with water and then treating with a wax-soap emulsion.
6. In a process for delustring formed filaments, the steps of treating them with a solution containing baryta containing approximately one gram of barium hydroxide per litre, and thereafter with a solution containing aluminum sulphate and glue, then rinsing with water.
7. In a process for deluatring formed illnmente, the steps of treating them with a solumama tion containing baryta containing approximately one gram of barium hydroxide per litre, and thereafter with a solution containing aluminum sulphate and glue, then rinsing with water and then treating with a wax-soap emulsion.
