SODA-PRINT PROCESS.

To all whom it may concern-.-

Be it known that I, ERNnsr CADGiiNE, a citizen of the Republic of France, residing at Englewood Cliffs, county of Bergen, and State of New Jersey, and I, JULEs'JEANoRos, a citizen of the United States, residing at Paterson, county of Passaic, and State of New Jersey, have invented certain new and useful Improvements in Soda-Print Processes, of which the following is a specification.

This invention relates to the printing of textile fabrics to produce brocaded or raised figured effects. In textile printing such effects are produced by what is known in the industry as the soda print process, which consists in the destruction by burning or otherwise, treating with a suitable chemical certain portions or sections of the fabric, the foundation or backing fabric of which consists of threads of different fibre from the threads which form the covering, the foundation threads usually being of animal fibre, asfor example, silk, and the other threads or threads to be destroyed, be ing of vegetable fibre, as for example, artificial silk or cotton. The fibres which constitute the threads of the foundation and the covering are obviously not limited to the example given, as silk may be used for the covering and any vegetable fibres for the foundation, or the entire fabric may consist of threads formed of the same fibres, having either the covering or foundation threads treated to resist the action of the chemical employed. The chemical is applied to the fabric usually by means of a printing roller provided with the required characteristics to produce the desired design, after which the fabric is subjected to heat to accelerate the reaction between the chemical and the threads to be destroyed. Obviously, a chemical is selected which will react with the threads to be destroyed, but which will be neutral with respect to the foundation threads. The reaction of the chemical with such threads is permitted to continue until the binding of certain of the threads to the foundation is destroyed and the fabric is then brushed, washed or otherwise-treated to remove the loosened threads, from the foundation fabric, thus leaving the covering thread intact in the untreated portipns to produce'the raised figures,

ever, have not been very successful, because of the unsurmountable difliculty of securin proper registry of the color printing wit% the reserved figures of the fabric after the soda printing has been completed, and the equally great difliculty of simultaneously printing the fabrics with the "burning or etching chemical and colors. While in the latter case it has been found possible to secure an accurate registration of the color and chemical during the printing, it has been found impossible to prevent the colors and chemicals from running.

It is the object of our invention to pro-.v

duce a new and improved soda printing process by means of which all of the reserved figured effects heretofore obtained may be secured and in addition any desired color effects may be produced upon the reserved figures; the color efi'ects obtainable with our process being practically unlimited and the outlines of the colored designs upon such figures being produced accurately with any desired degree of sharpness or contrast.

In its broadest aspects, our process consists in printing the desired color effects and patterns upon the face of the fabric and mixing with the colors, a resist composition which is-preferably colorless, and which will prevent the chemical used for destroying the threads to be destroyed from attacking or reacting with the threads of the portions to be reserved. The resist composition may either form a protective coating upon the reserved portions or may be such that it will react with the soda print chemical so as to neutralize the effect thereof. After the combined coloring and resist composition is applied, the entire face or back of the goods is then coated with #1 9da print chemical,

as for example, aluminum chloride or alu-. minum sulphate, when the threads to be de--;' stroyed consist of vegetable fibre. While the coating of the fabric with the soda print may be done in any suitable or convenient manner, we have found it desirable to use a padding roller the entire surface of which is covered with mille points, or as commonly termed in the art petit points. The fabric is then subjected to heat, preferablyby passing it through a dry box and as the soda print chemical will attack and react with all of the threads which have not been coated with the combined coloring and resist composition, the'binding of such'threads with the foundation fabric will be destroyed and will cause such threads to become loosened from the foundation so that they will either fall away from the foundation or may be readily removed therefrom by carding or brushing.

The usual manner of carrying out the well known soda print process is to execute the print upon the back or the face of the goods and is performed on' the goods either: (a) when theyare in the raw state, (b) when they are in the boiled off state; (0) when they are in the dyed state; or (d) after a regular print. As heretofore pointed out, it has been found a practical impossibility to secure a proper registration of the soda print design with the regular color print and to produce a commercially practical product. While our process can be performed upon the goods when in the raw, boiled-off or dyed state, the following is the preferred sequence of operations which we employ. The regular boil--off of the goods is performed, after which they are dyed, then the color printing of the goods as hereinbefore described by the use of a resist composition, is performed, and after the color printing has been completed the goods are steamed to fix the colors. The printed fabrics are now ready for the application of the burning composition or chemical which is applied evenly over the entire surface of either side of the goods, but preferably over the face thereof; after which the goods, with the chemical applied thereto, are subjected to the required heat to cause the unreserved threads to be destroyed as with the regular soda print. It will be obvious that the threads will only be destroyed upon those parts of the goods which have not; been coated with the resist color compositions, used in the first printing. After the burning of the unreserved threads has been completed, the goods are then washed, brushed or otherwise treated, to remove the loose threads and the chemicals use-d in the soda print, and are then subjected to the regular finishing operations.

We have found that aluminum chloride, or aluminum sulphate, or a mixture of these two chemicals, is satifactory for performing the burning or etching of the goods; and a typical example of a composition successfully employed by us for the combined print and resist printing consists of a regular gum arabic printing color of any desired shade, to which is added 25 per cent of blood albumen, 7 per.cent of chromium acetate and 5 per cent of sodium acetate. The albumen assists the coagulation. of the compound and forms a waterproofing for the printed colors; the chromium acetate assists in the waterproofing and also acts to fix the colors; and the sodium acetate helps to protect the printed parts by neutralizing the burning effects of the aluminum compounds. It will be understood that the combined color and soda print compositions may be varied considerably in accordance with the nature of the goods to be treated, and that the resist composition added to the regular printing color will obviously be varied according to the chemical employed for burning the threads to be destroyed.

Furthermore, the brocaded efiects which may be obtained by the use of our process are not limited ,to a fabric containing animal and vegetable fibres as hereinbefore described, but the process is equally applicable to plain cotton fabrics, to cotton fabrics in which the entire fabric or either the foundation or covering is constructed of mercerized or other threads to resemble silk, or to fabrics constructed in whole or in part of any artificial silks, acetylated cellulose or otherwise, provided that the fibres of the threads which are to form the foundation of the fabric are treated with a protective chemical before weaving. Tt will thus be seen that our process may be carried out not only with fabrics constructed of threads of different species, but also with fabrics constructed of all cotton fibres; all animal fibres, or all vegetable fibres if one set of the threads has been treated with a protective chemical before weaving.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is:
