COATED FABRIC AND METHOD OF MAKING SAME.

Application led April 14, 1920, Serial No. 373,956. 4Renewed October 6, i925.

To all 'whom it may concern:

Be it known that I, Jassn H. MASON, a citizen of the United States, residing at have invented certain new and useful Improvements in Coated Fabrics and Methods of Making Same of which I declare the following to bel a full, clear, and exact description.

This invention relates to improvements in coated fabrics and the method of making more particularly to rubber-coated fabrics in which an ornamental effect is roduced by embossing the rubber-coated fa ric.

- Heretofore, it has been impossible'to produce a two-color or two-tone effect in rubber-coated fabrics except by printing on the rubber-coated fabric any desired design in which one or more colors might be used. This method has been and is objectionable because the design thus produced on the coated fabric has aflat appearance and looks chea The product made in this manner, there ore does not appeal to the buying public as a high ade material and it has not been possible 1n this manner to simulate the effect roduced on real leather. As a rule the co ored design thus printed on the vcoated fabric has a tendency to rub ofi'.

One of the objects of my invention is to provideV a new type of coated-fabric in which an ornamental effect is produced in more than one tone or color, giving a rich and pleasing appearance to the product.

Another object of my invention is t'o` provide a rubber-'coated fabric which is finished in more than one tone or color so as to simulate themulti-color effect produced in iinishing natural leather.

Another object of my invention is to pro-- vide an improved`process for producinga multi-color effect in rubber-coated fabrics.

In Fig. 1 lof the drawing there is illus- -trated a section through fabric coated in accordance with the processes indicated in the application, and

Fig. 2 is a section through a base fabric having a modified formation. l

In. general, I accomplish the objects of my mvention and avold the objectionable features of prior methods which have been indit'ed above, by coating a fabric backing with a base coat of rubber, embossing the base coat, and appl ing a surface coating carrying pigment, w ich may be of a different color from the base coat, so that the surface coating lodges in the crevices formed in the :base coat by the embossing operation, but-is rubbed oifof the high spots of the base coat. The coated fabric produced in accordance with my invention, in general, comprises a fabric backing having a base coat of rubber with crevices therein in which av surface coating carrying pigment, which may be of a different color from the base coat, is lodged.

In carrying out my invention, I first apply to a suitable fabric backing, such as a drill, sateen or moleskin, a base coat of rubber composition. This rubber composition may be any satisfactory rubberizing compound. The particular formula does not form a part of my invention, appropriate formulae being Well known to those skilled in the rubber art, it being understood that the ingredients will vary depending upon the character, quality and color of the coating to be produced. This rubber com ound may be applied to the bac-king on a ca ender or spreading machine in the manner well understood in the rubber art.

After the base coat is applied to the backing, it is embossed in the usual manner, either by passing the rubber-coated fabric between embossing rolls or by impressing the desired design on the base coat by embossing plates ina press. l

After the embossing operation, a soup coat or rub is applied as will be described hereinafter. This rub comprises a .suitable carrier containing pigment or dye to give color to the rub. may be such as to give the rub a different color from the base coat so that the multicolor effect may be produced by the cont-rast between the color of the rub and that of the base coat, as will appear more clearly hereinafter. I have secured very desirable results by the use of two different carriers for the pigment, both of which I-wi1l describe, it being understood that either of these carriers may be employed. I may use as acarrier for thepigment in the rub coat a vulcanzing varnish made up of a vegetable The pigment used a drying 'oil 'and sulphur. For instance, I

l may make up a rub coat by adding about eight pounds of sulphur to about twenty-fiveA gallons of boiled linseed oil and add to this the pigments or dyes necessary to give the rub coat the desired color. These ingrcdients are intimately mixed and the mixture thinned down until it is of the proper consistency for application to the base coat. Instead of the rub coat described above, I may use one in which rubber cement is used as the carrier for the pigment. For instance, I may dissolve rubber in a suitable rubber solvent, add the sulphur necessary for vulcanization and the pigments or dyes necessary to give the desired color to the rub coat. These ingredients are intimately mixed, brought to the proper consistency, and applied to the base coat in the manner which I will describe.

The rub coat is applied to the base coat by drawing the fabric carrying the embossed rubber base coat beneath a spreading knife while the fluid rub coat is fed in front of the spreading knife. This method of applying a coating is well known in the art and needs no further description to be understood by those familiar with this art. The tension of the fabric and the rate of feed of the rub coat in front of the knife is regulated and adjusted so` that the rub coat lodges in the crevices formed in the .base coat by the embossing operation and is rubbed otf of the high spots by the spreading knife so that the base coat is exposed at the high spots.

After the application of the rub coat, I may, when desired, apply a transparent top coat of a clear vulcanizing varnish. For instance, I add about eight pounds of sulphur to about twenty-five gallons of boiled linseed oil, mix these ingredients intimately', thin to the proper consistency-and apply by a spreading knife. I use a transparent top coat in cases where the pigments are of such nature that the finished product would otherwise be likely to crock or rub o.

The material coated as described above is then fed in the heater where it is cured or vulcanized by exposure to heat in the manner well known in the art. The curing operation may follow directly after the application of the rub coat or, in cases where a top coat is applied, it may follow the application of the top coat.

It will appear that the material produced in accordance with the process which I have described is characterized by a base coat of rubber having crevices or depressions in which a suitable vulcanizing carrier carrying pigment is deposited, the pigment being of a dilferent or contrasting color from the color of the base coat, so that a two-color or two-tone effect is obtained in this way. Since the ,final step in?, the process is the vulcanizing of all of the materials deposited on the backing, they are all amalgamated into a single compact mass so that the pigments will not crock or rub off. This is particularly true where they arc covered by atop coat as described.

I am aware that the particular embodiment of my invention, which I have described here, is succeptible of considerable variation without departing from the spirit of my invention and, therefore, I desire to claim the same broadly, as well as specifically, as indicated by the appended claims.
