DII'i'EBENTIAL COLORED FABRIC AND METHOD OF MAKING- SAME.
Io mun This invention relates to fabric having a design thereon which design is due to the difference of the effects of dyes upon the material of which the fabric is com osed and the material with which the fabric is printed.
An object of our invention is to provide a fabric having a design thereon, which deslgn is not made by the ordinary process of printing by means of dyes or other colors, but which is obtained by the differential dyeing of the fabric due to the printing or the application by other means of material upon such fabric, which material is affected by dyes in a manner different from the material of which the fabric is composed.
Another object of our invention is to'providea fabric which is cross-dyed, wherein color effect or design produced is independent of the weave but which may be produced in any desired configuration.
Another object of our invention is to roduce a design by cross-dyeing upon a fa ric composed at least in art of an orgamc derivative of cellulose aving a design of cellulose rinted thereon.
Other 0 jects of our invention will appear from the following detailed description.
It is 'well known that cellulose, whether natural cellulose such as cotton, or reconstituted cellulose such as is obtained from viscose, reacts in a different manner from cellulose acetate silk, natural silk or wool towards many dyes, or that differential effects may be obtained b dyeing a mixture of cellulose and these fibres in one bath containing a dye or mixture of dyes. This principle is used commonly in cross-dyeing.
mixed fabrics made by weaving yarns of cotton and one of the above mentioned materials. Obviousl in this method, the differential color efihct depends entirely upon the nature of the weave. In accordance with our invention, cross-dyeing effects are obtained by making a deslgn of cellulose, irrespective of weaving, on a fabric which contains at least some yarn of a material other than cellulose, and then immersing the fabric in a bath containing one or more dyes having different coloring effects upon the cotton and the other material.
The fabric to be treated may be made entirely of an organic derivative of cellulose, such as organic esters of cellulose or organic ethers of cellulose. Examples of organic Application filed August 18, 1927- Serlal No. 212,882.
esters of cellulose that may be used are cellulose formate, cellulose acetate, cellulose propionate and cellulose butyrate. Examples of cellulose ethers that may be used are methyl cellulose and ethyl cellulose. Or the fabrlc may be composed of a mixture of any of the above organic derivatives of cellulose with one or more other fibres such as natural silk, wool, cotton or reconstituted cellulose. Furthermore the fabric to be treated may be com osed wholly of silk or wool or a mixture 0 these animal fibres.
The fabric, constituted as above set forth, is printed with a material whose behavior toward dyestuffs is different from that of organic derivative of cellulose, natural silk or wool. Among the materials used for thispurpose may be mentioned cellulose, gelatin or casein. The so printed fabric is then dyed in a differential dye bath.
' One mode of carrying out our invention is to print the fabric, constituted as above set forth, with one of the common solutions of cellulose used in making reconstituted cellulose artificual silk, such as a solution of cellulose xanthate (viscose) or a cuprammonium solution of cellulose. The thickness or concentration of the cellulose solution to be used for printing may be varied in accordance with the type of fabric to be treated or the nature of the design desired. After the fabric has been printed with the cellulose solution, it is permitted to dry if desired. The fabric is then treated to reconvert the cellulose compound of the print back to cellulose. For instance, if viscose has been used for printing, the cellulose is reconstituted by immersing the fabric in a dilute aqueous solution of sulphuric acid. Better results may be obtained by using a solution of sodium acid sulfate, ora solution of sodium acid sulfate and sodium sulfate as the precipitating bath. The fabric now has a design of cellulose imprinted or impressed upon it. The fabric may now be washed and/or dried if desired. It is now ready for the dyeing treatment.
The fabric, which contains at least some fibres or yarns of one or more of the following substances, viz, organic derivative of cellulose, silk, wool, or some other fibre other than cellulose, and which has a design of cellulose imprinted thereon, is now placed in a dye bath which contains one or more" dyes which act differently towards the cellulose and the other material of which at least some of the fibres are composed. Thus the dye may color cellulose and not color the other material, or it may color the cellulose more deeply than the other material. ()n the other hand the dye may color the other material and not color the cellulose or else color the other material more deeply than the cellulose. Again, the dye bath may contain two or more dyes, one of which colors the other material and not the cellulose, while the other of which colors the cellulose but not the other material. When using such mixtures of dyes, it will be seen that by immersion of the fabric so printed with cellulose in a single dye bath, a two-colored design may be produced. The fabric is then given the ordinary finishing treatment.
When the fabric treated according to the above process is made of mixed yarns containing cotton, such as mixed cellulose acetate and cotton, mixed natural silk and cotton, or mixed wool and cotton, the cotton yarn will be dyed or remain undyed in the same manner as the cellulose of the print. This will give the double effect of ordinary cross-dyeing of mixed fabrics together with the effect of the cross-dyeing of the printed cellulose design.
In another application of our invention, the fabric constituted as above set forth, is printed with a solution of gelatin or a solution of casein, and then dyed. The parts of the fabric printed by the gelatin or casein are not affected by the dyes and thus differential color effects are obtained. The gelatin or casein is then washed off by appropriate treatment and the fabric is then finished in any appropriate manner.
To further elucidate the mode of carrying out our invention, the following specific examples are given by way of illustration only:
Example I Per cent.
SRA blue IV 0.5 GB cotton fast yellow B (color index #842 Schultz-Julius #617) 1.0
Glaubers salt (sodium sulfate) 30 The percentages given are based on the weight of the fabric treated.
After finishing in the ordinary manner the background of the fabric is colored blue, while the design is of a greenish color due to the combined effects of the yellow color of the cellulose print and the blue of the cellulose fabric under the print.
Example I I SRA blue IV CR cotton fast scarlet 4 BS (color index #327 Schultz-Julius #279) 0.5 Glaubers salt 30 The percentages given are based on the weight of the fabric treated.
After finishing in the ordinar manner the background of the fabric is co ored blue While the design is of a greyish-purple due to the combination of the red color of the cellulose acetate print and the blue color of the cellulose acetate fabric under the print.
Example [11.
A cellulose acetate satin is printed with cellulose in the maner set forth in Example I. Itis then immersed in a dye bath containing a dye which dyes cellulose brown but which does not affect the cellulose acetate. This dye bath is made up as follows:

After finishing in the ordinary manner the background of the fabric is of the original natural color of the cellulose acetate silk (white) while the design is brown.
