Description

Patented Mar. 1, 1932 UNITED STATES PATENT OFFICE ROBERT PETITDIDIER AND FRANCOIS VICTOR FEYNIER, OF PARIS, FRANCE, ASSIGNORS TO ETABLISSEMENTS PETITDIDIER (ANCIENNE MAISON JOLLY-BELIN), OF ST.-
DENIS, FRANCE COLOR PRINTING PROCESS FOR TEXTILE FABRICS No Drawing. App1ication filed July 12, 1926, Serial No. 122,039, and in France August 1, 1925.
The present invention has for its object a color printing process for textile fabrics of a composite character, which essentially consist on the one hand of artificial silk made of acetate of cellulose, and on the other hand of cotton, flax, natural silk, wool, or artificial fibres such as viscose silk, and the fabric may comprise the whole or a part of these various fibres.
The said process is based upon a most striking observation that certain colors having anthraquinone as a base, such as the amino hydroxy, diamino, tetramino, methylamino and di-methyl-diamino colors, certain but little affected by the action of the reducing agent which consists of sodium hydrosulfite, whereas on the contrary, under the action of the said reducing agent, the said colors Will disappear almost entirely from all the other fibres, so that by printing upon the said composite fabrics, we are enabled to obtain an appearance different from what is offered by the known methods. In particular, these fabrics show multi-colored or variegated eflects upon similar cellulose acetate threads to the exclusion of the other threads of the fabric.
Certain of the acid colors such as citronine' (diazoted sulfanilic acid+diphenylamin strongly nit-rated) and rocceline (diazoted naphthionic-acid+betanaphtol) soluble blue for silk (disulfonated triphenyl-para-ros aniline), and certain basic colors after a preliminary mordanting of the fabric with tannin or acetanol (pyridine nitrate), have the same properties.
these conditions we already The color printing process comprises the following operations, in the case of fabrics consisting of a mixture of cellulose acetate silk and viscose silk or cotton forming the (6) The printed fabric is treated in a steam operated autoclave for fixing the colors.v During this operation, the color becomes fixed upon the cellulose acetate fibre, but it is only incompletely fixed upon the cotton backing and upon the viscose silk.
(0) The fabric is then rinsed. During this operation, a part of the colors, which impregnated the cotton backing and the viscose will be removed.
(d) The fabric is finally treated in a sodium hydrosulfite bath, containing 1 gram of hydrosulfite per liter of water, the bath being heated to about degrees C. During this operation, the color will be discharged from al parts of the fabric except the cellulose acetate fibres.
The fabric can be utilized in this condition, or it may be treated in a dye bath which acts upon the cotton backing, without any marked change in the color of the cellulose acetate.
Ina modification of our said process, we dispense with the sodium-hydrosulfite bath, i. e. the fabric is utilized in the state in which it appears at the end of operation (0) for in obtain an excellent effect of color upon color.
IV hen the fabric to be printed has a backing of natural silk, we prefer to increase the amount of hydrosulfite from 1 to 2 or 3 grams per liter of water, according to the quality of the silk. In this manner the color of the natural silk backing is diminished, Whereas the colors printed on the cellulose acetate silkwith dyestuffs having anthraquinone as a base as above specified will preserve their brilliancy, and will assume suitable shades according to the duration and the temperature of the treatment.
Another feature consists in the fact that we may ellace the traces of color which still exist upon the backing, by treating the fabric hydrosulfite bath to in a bath containing 0.001 by volume of sulfuric acid at 66 degrees B., the bath having preferably a temperature of 80 degrees C.
It may happen that by reason of the strength of the colors employed for print ng the acetate of cellulose, the backing which should be white may still remain slightly colored, which may be prejudicial to the appearance of the f brie when the backing 1s not to be covered by an additional dyeing. However by treating the fabric-after printing the cellulose acetate as above disclosed-4n a bath of potassium permanganate and then in a solution of sodium bisulfit'e, the traces of color which somewhat stain the backing will entirely disappear. V
The proportions to be adopted, which are given by way of example, are 20 to 25 grams of potassium, permanganate in a bath of 100 grams of water, and the density of the sodium bisulfite solution may be about 15 degrees B.
In the same manner as for the fabrics with a cotton backing, the fabric thus prepared may be treated in a dye bath which acts upon the natural silk backing, without any marked change in the color imparted to the cellulose acetate. With fabrics having a wool backing, we prefer to increase the strength of the 5 grams per liter of water. e thus obtain upon the wool backing a sufficient attenuation of the printing to obtain, by a subsequent dyeing, a uniform backing, and the shades of color upon the acetate of cellulose will always preserve their original brilliancy. 7
Obviously, the aforesaid process is susceptible of various modifications in its execution, without departing from the spirit of the invention. In particular, the indications concerning the proportions and temperatures may be modified \Vhat we claim is:
1. A color printing process for composite fabrics composed, of cellulose acetate artificial silk mixed with other suitable fibers which consists in printing the fabric with colors of an anthraquinone base adapted to produce dyeing reactions upon the cellulose acetate, fixing the printed colors and rinsing the fabric in a reducing bath for removing all color from the fibers which are not the cellulose acetate fibers.
2. A color printing process for composite fabrics composed of cellulose acetate artificial silk mixed with other suitable fibers which consists in printing the fabric with colors of an anthraquinone base adapted to produce dyeing reactions upon the cellulose acetate, fixing the printed colors and rinsing the fabric in a bath of sodium hydrosulfite for removing all color from the fibers which are not the cellulose acetate fibers.
3. A color printing process for composite fabrics composed of cellulose acetate artificial silk mixed with other suitable fibers which consists in printing the fabric with colors of an anthraquinone base and adapted to produce dyeing reactions upon the cellulose acetate, fixing the printed colors, rinsing the fabric in a reducing bath for removing all color from the fibers which are not the cellulose acetate fibers and subsequently dyeing the fabric in a bath which reacts upon the fibers of the fabric without changing the color of the cellulose acetate fibers.
4:. A color printing process for composite fabric of cellulose acetate artificial silk mixed with other suitable fibers which consists in printing the fabric with colors of an anthraquinone base adapted to produce dyeing reactions upon the cellulose acetate, fixing the printed colors, rinsing the fabric in a bath of sodium hydrosulfite containing from 1 to.
5 grams of hydrosulfite per liter of water for removing all the color from the fibers which are not the cellulose acetate fibers.
5. A color printing process for compositefabrics composed of cellulose acetate artificial silk mixed with other suitable fibers, which comprises printing the fabric with colors of an anthraquinone base adapted to produce dyeing reactions upon the cellulose acetate, fixing the printed colors and rinsing the fabric successively in a bath of sodium hydrosulfite, in abath of potassium permanganate and in a solution of sodium bisulfite, for removing all color from the fibers which are not the cellulose acetate fibers.
6. A color printing process for composite fabrics composed of cellulose acetate artificial silk mixed with other suitable fibers, which comprises printing thefabric with colors of an anthraquinone base adapted to produce dyeing reactions upon the cellulose acetate, fixing the printed colors and rinsing the fabric successively in a bath of sodium hydrosulfite, in a bath of potassium permanganate containing from 20 to 25 grams of permanganate for 100 grams of water and in a sodium bisulfite solution having a density of about 15 degrees 136. for removing all color from the fibers which are not the cellulose acetate fibers.
In testimony whereof we affix our signatures.
