Description

UNITED STATES PATENT OFFICE.
A DOLEv I-IOZ, OF LINDAU, GERMANY, ASSIGNOR OF ONE-HALF TO ALBERT WESTER-MANN, OF HOTTINGEN, SWITZERLAND, AND J OSEF ZERVAS, OF
NEW YORK, N. Y.
COLORS F OR PRINTING ON TEXTILE FABRICS.
SPECIFICATION forming part of Letters Patent No. 486,873, dated November 29, 1892. Application filed May 28. 1891. Serial No. 394,340. (No specimens.)
To all whom, it may concern:.
Be it known that I, ADOLF HOZ, a citizen of the Republic of Switzerland-residing at Lindau, in the Kingdom of Bavaria and Empire of Germany, have invented certain new and useful Improvements in the Manufacture of Colors for Printing on Textile Fabrics, of which the following is a specification.
The object of this invention is to supply for the printing of textile and other fabrics in colors an improved color composition by which the printing may be performed directly on any fabric without requiring a preparatory treatment for the same and without necessitating a subsequent finishing treatment after the color is applied, the fabric being completely printed as soon as the color is applied thereto; and the invention consists of a color composition which partakes to some extent of the character of the water-soluble colors heretofore used for printing on textile fabrics and of the fatty inks or colors used in lithographic and type printing and which consists of a mixture of a dye-stud soluble in water or alcohol, a fatty substance, and a thickening substancesuch as linseed-oil varnish-to which may be added soap, oil, wax, asphaltum, manganese, or other fatty or drying substances, according to the special dye-stud employed.
For illustrating the peculiar characteristics ofmy improved color composition I will now describe the preparation of three different kinds of the same.
First group-benzidinc colors or so-called direct-coloring dyc-stufls.-'lhe dye-stuffs of this group are mixed with the required quantity of water, in which a mordant-such as phosphate of soda-is dissolved, so that the proper developing of the color is produced. 40 The substances which serve to fix the dyestufi-such as sulphate of copper and albu men-are next added and dissolved by thoroughly stirring the solution. The fatty substance is nextadded and then the thickening substance, which consists of linseed-oil varnish, mixed with the required quantity of wax, fat, &c., or with the required quantities of acids and salts. A water-soluble dye-stuff is thus combined with an acid-containing alkaline or neutral mordant and fixing substances,
with a fatty substance, and with a thickening substance.
Second gr0upam'linc c0l0rs.-The aniline color is mixed with water and so-called Turkey-red oil and thoroughly dissolved in the same by boiling. The color is then precipitated by means of a suitable mineral acid, the fatty residue carefullywashed and mixed with linseed or other oil, so as to form a kind of paste, then mixed with afdrier, and finally mixed with linseed-oil varnish or other suitable varnish. In this case a color is obtained which conta ns oleic acid and which is thickened with varnish without any other substance. By adding thickening substances such as soaps, fats, asphalt-um, &c.the printing is greatly facilitated. According to the quantity of varnish used the print obtains a more or less glossy appearance, while by the substances that are added to the color a more or less efiiect-ive resistance against washing and light is imparted to the same.
Third group-alizarine colorsQ-From the alizarine colors a varnish color is obtained by subjecting them to the action of steam under pressure, after which the fatty substances are added in the same manneras with the aniline colors.
My improved color composition for printing in colors on textile and other fabrics differs 8o essentially from the water or alcohol soluble colors heretofore employed, as neither the thickening of the color with starch nor fixing substances are required for properly developing the colors. All the diderent water-soluble dye-stuffs which were heretofore used for printing on cotton and other textile fabrics can be used for producing my color composition by mixing it with a fatty substance and a thickening substance, such as linseed-oil 9o varnish. The fabrics are then printed without any preparatory or subsequent treatment.
In some of the water-soluble colors a mordant for developing the color is necessary. While by the former method of. printing on textile 5 fabrics only water-solubledye-stuffs could be used, my improved color composition produces the changing of the water-solubledyestuffs by the addition of varnish into a fixed color, which can be printed, fixed, and devel- IOO oped on the fabric without any special drying or fixing process, except in some cases when they are subjected to steam either at atmospheric or higher pressure. By the old method of printing in colors the thickening substance has to be removed by washing,while by my improved color composition no Washing is required, as a portion of said substance evaporates, while the remaining portion is retained without being objectionable. In the former method of printing the color was only developed by the final treatment of the fabric, while by my method the color is ready as soon as the same is printed on the fabric, so that any desired tint or shade can be produced without the least difficulty. By the former method the color compositions had to be adapted to the peculiar characteristics of the fiber, while my new color composition can be used for printing on every textile or other fabric, whether it be cotton, wool, silk,'leather, or other material.
In testimony that I claim the foregoing as' my invention I have signed my name in presence of two subscribing witnesses.
