Description
Patented Aug. 30, 1932 UNITED STATES PATENT OFFICE JOHANNJ'O SEF STOCKLY, OF TELTOW-SEEHOF, NEAR BERLIN, AND ERHARD WITTE, F BERLIN-LICHTERFELD, GERMANY, ASSIGNORS, BY' MESNE ASSIGNMENTS, T0 AMERICAN GLANZSTOFF CORPORATION, OF NEW YORK, N. Y.
PROCESS FOR THE MANUFACTURE OF ARTIFICIAL SILK, HAIR, BANDS AND SIMILAR PRODUCTS OF DIMINISHED LUSTER No Drawing. Application filed April 5, 1929, Serial No. 352,894, and in Germany April 5, 1928.
It has already been proposed to add caoutchouc to spinning solutions, in order to impart to the threads spun from such solutions the valuable properties of the caoutchouc. For
that purpose it was necessary to dissolve the caoutchouc by means of suitable solvents and to incorporate the said solution in order to obtain a homogenous mixture with the viscose.
According to the present invention it is not desiredato obtain a homogenous dissolution of the caoutchouc in the spinning solution or the products produced thereof, but merely on enrulsification of the added substance in the spinning solution and a minute but always non-homogenous distribution of the caoutchouc in the products manufactured. For that purpose a primary productof the caoutchouc, i. e. latex is mixed with the spinning 9 solution, suitably in the form of the known commercial concentrates. The emulsification of the latex can be easily carried through in all such spinning solutions which are alkaline for instance in the viscose and in the cuprammonium solution of cellulose. The spinning solutions uniformly mixed with latex can be spun in the .customary manner without any difliculty. When using viscose it is possible to make use in particular of acid precipitatingbaths generally knownvin the art. The small globules of latex having at the most a diameter of 0.02 millimetres, will passwithoutany hindrance through the fine but rather spacious spinning apertures without choking the latter.
The globules of latex having coagulated into caoutchouc can be found after precipi tation, washing and finishing of the products ly divided state. The latex obtained in the or luster in proportion to the quantity and manufactured,embedded in the mass in a fine-' concentration of the latex preparation used. The latex preparations and concentrations respectively may be used in a vulcanizedor not vulcanized state and in the claims where latex is referred to, either of said forms is intended. The invention may be applied to the manufacture of artificial silk or staple fibre from viscose, cuprammonium solution of cellulose having any desired degree of dull luster. It is also particularly adapted for the manufacture of artificial horse hair and bands, in which manufacturers and the industry specially give preference to products showing a wax-like or dull surface. For influencing the luster of artificial silkin order to obtain almost any degree of the luster of the usual artificial silk down to perfect dullness, it will sufiice to add to the spinning solutions a minimum quantity of 1 per cent up to about a maximum quantity of about 10 per cent of the known commercial per cent concentrates of latex, calculated on the spinning material contained in the spinning solution. By changing the quantity of the added substance it is possible to diminish the luster of the products obtained, in any desired manner.
In the case of artificial horse hair or hands, where in particular a pronounced dullness of the article is desired, there is no difficulty to add to the spinning solutions or the products respectively a still higher percentage of added substance.
Example I Example [I The process is carriedthrough exactly in the same manner as stated in Example I with the difference however, that the 60 per cent concentrate of latex is applied in its vulcanized form. I
' Ewample III To a solution of. cuprammonium cellulose,- containing 7 per cent of cellulose, 3 per cent of copper and per cent of ammonia, about 4 grams per litre of the 60 per cent concentrate of latex either vulcanized or not, are added, whereupon the well agitated solution is spunifin the well known manner.
Weclaim: 1. The method of producing artificial silk and the like of diminished luster comprising in combination the step of adding to an v alkaline cellulosic solution a concentrate of:
caoutchouc latex, spinning the mixture into a thread and treating the thread so obtained in the usual manner.
tex, spinning the solution into filaments and treating the filaments so obtained in the usual manner. 1 r
4. The method of producing artificial silk and the like of diminished luster,-compris-- ing in combination, the step of adding to an alkaline cellulosic spinning solution concentrates of caoutchouc latex, the quantity thereof ranging from one to ten per cent calculated on the quantity of the spinning substance contained in the spinning solution, spinning the mixture into artificial filaments and in treating the filaments so obtained in the usual manner. I a
5. The method of producing artificial silk and the like of diminished luster, compris-' ing in combination, the step of adding to a cuprammonium spinning solution concent-rates of caoutchouc latex, the quantity thereof ranging-from one to ten per cent calculated on the quantity of the spinning substance contained in the spinning solution,
- spinning the mixture into artificial filaments and in treating the filaments so obtained in the usual manner.
6. The method of producing artificial silk and the like of diminished luster, comprising in combination the step of uniformly emulsifying concentrates of caoutchouc latex in an alkaline cellulosic spinning solution, spinning the mixture into filaments, and treating the filaments so formed in the usual manner.
7. The method of producing artificial silk I and the like of diminished luster comprising 1n combination the steps of adding to an alkaline cellulose solution a concentrate of latex in vulcanized form, spinning the mixture into a thread and treating the thread so obtained in the usual manner.
8. A cellulosic artificial silk filament of the class consistingof viscose and cu'prammonium filaments having its luster diminished by having dispersed through its mass a concentrate of latex in vulcanized form.-
9. A cellulosic artificial silk filament of the class consisting of viscose and cuprammonium filaments havin its luster diminished by having disperse through its mass a concentrate of latex the quantity thereof ranging from one to ten r cent calculated on the quantity of the cellulose in the filament. 4
