' STENGILING AND DYEING FABRICS AND THE LIKE.

Application filed November 5, 1925, Serial No. 67 ,038,and in Germany November 7, 1924.

My invention refers to the art of producing coloured patterns on porous materials such as fabric and the like and more especially to the manner of stencili'ng which originated in Java and is commonlyknown as batik dyeing. As is well known to those skilled in the art this Javan method is based on the impregnation of those parts of the fabric, which shall not be dyed, with Wax, paraffin or some other resist, preferably by immersing a metal stencil inhot-fiuid wax and then placing it onto the fabric, the fluid wax entering the fabric and protecting the impregnated portion against the dye solutime. This method can be easily practised at the average temperature of 40 0., prevailing as a rule in a hot country like Java, the more so as the wax produced by the J avan bees remains fluid for a longer periodthan the Wax of the bees reared in Europe and America. In consequence of the materially lower average temperature prevailing in these latter countries and of the more rapid solidification of the wax the utilization of the J avan batik process encounters serious difiiculties. both in Europe and America.

Moreover the J avan process does not allow impregnating several layers of fabric or the like at a time and in consequence thereof a piece of fabric impregnated only on one side HllSl) be turned over in order to treat the rear s1 e.

It is an object of my invention to overcome all these difliculties and to render the batik dyeing process applicable independently of the temperature of the air and of the melting point of the wax. It is a further object of my invention to render this process adapted for a production on a large scale.

tion to render the process more eflicient as regards the quality of the products obtained. With these and other objects in view I will now proceed to describe my invention and how the same is to be performed, having reference to the drawings which illustrate.

diagrammatically and by way of example several modes of carrying my invention into practice.

It placing the fabric, paper or the like on a support containing or consisting of wax or other resist and applying heat to those parts of the fabric or the like, which it is intended to impregnate with the wax. so as to protect it from being dyed. The heat will It is a further object of my invenis based substantially on the step of cause the wax or the like to melt below these parts of the fabric, the fluid wax being then absorbed by these parts. Preferably heat is applied by pressing onto the fabric a metal stencil which has heated to a temperature suflicing to melt someof the wax under the fabric inserted between them.

In the drawings Fig. 1 is a vertical section illustrating the above mode of proceeding.

Fig. 2 is a similar view illustrating means.

whereby the method of stencilin-g can be practised in a continuous manner.

Figs. 3 and 4 are similar views illustrating two modifications of the arrangement shown in Fig. 1.

Referring first to Fig. 1, a is a metal stencil, b is a piece or web of the fabric to be impregnated and c is a sheet of wax, parafiin or the like. By pressing the heated stencil it onto the fabric, some of the wax on the surface of c is melted and readily absorbed by the fabric. Obviously the stencil a can be formed and engraved in any suitable manner in order to produce the pattern desired in each individual case.

In the arrangement disclosed in Fig. 2, a is an engraved metal cylinder which replaces the ordinary stencil and 0' is a wax cylinder. 7; is the web of fabric travelling between them. Obviously, when the metal cylinder a is heated in any suitable manner, it will cause the wax on the surface of cylinder 0 to melt and to be absorbed by the fabric 1) while this latter is pulled through'between them. 1

In the modification illustrated in Fig. 3, a is the stencil and b the fabric to be impregnated, c is a piece of fabric thoroughly impreviously been pregnated with the resist such as wax, f is a piece of oil cloth or the like and (l is a yielding support formed by a piece of felt or the like. Here the sheet of pure wax shown in Fig. 1 is replaced by a Web of porous materlal impregnated with the resist, which may prove useful in many cases, and this impregnated sheet can be advanced together with the fabric tobe impregnated which could not be done as easily in the case of a solid sheet of wax.

In the modification illustrated in 4 means are provided .whereby the iece of fabric or the like to be impregnate is prevented from stickin to the wax-s11 ort when this latter so idifies. If the a ric were allowed to stick to the wax one side of the layer of resist would be torn and this sart of the fabric could be attacked by the yestufl solution. In order to prevent means 'such as clampingl blocks a are l on the la er of wax c, t ese clampin locks holding t e fabric 6, which shall be mpregnated, m stretched condition above the wax bodyIsfo as tokeep it in spaced relation thereto. fabric by means of the stenci a this part of the fabric is pressed onto the wax support in order to be impregnated but on being relieved of the pressure the fabric will be detached at once from the wax" by its elasticity before the wax has solidified.

Obviously several superposed layers of fabric, paper or the like can be acted upon simultaneously by the stencil and it is there- -fore possible to insert a folded iece of fabric or the like between the stenci and the wax and by a single impression of the stencil to impregnate several portions of the piece of fabric in a strictly identical and symmetrical manner.

Inasmuch as the wax absorbed by the fabric solidifies at once, the fabric or the like can be dyed-without any loss of time pressure is now ap lied onto the olding the fabric to and after having dried can be impregnated in another place.

The products obtained by this process are not only equal to but in most cases superior to those produced by hand and in the ordinary manner practised in Java.

I wish it to be understood that I do not desire to be limited to the exact materials, operations and means described and illustrated, for obvious modifications will occur to Ia rson skilled in the art.
