Description

Patented Sept. 13, 1932 T E S OFFICE JOHN E. GEORGE, OF ST. LOUIS, MISSOURI, ASSIGNOR TO 'IHEALLIGATOR COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF DELAWARE FABRIC AND PROCESS OF MAKING THE SAME No Drawing.

My invention relates to a process of treating a fabric, such for example, as a woven cotton fabric commercially known as balloon cloth, whereby, when certain preferred materials are employed, a metallic sheen is imparted to both surfaces but one surface is given a different appearance from the other. My process may also be carried out in such manner that the fabric is rendered 11o waterproof and made a suitable and attractive material for use in the manufacture of raincoats and other waterproof garments.

The process comprises passing the cloth through a liquid bath, preferably of the com- 15 position hereinafter set forth, and then passing it between rolls to remove the surplus liquid and to so govern the disposition of the pigment content thereof as to produce the result desired. This latter may be accomplished by employing a roll having a rigid surface in cooperation with another having a resilient surface and I have successfully employed a smooth steel roll in cooperation with a smooth rubber roll, After the treated fabric has been passed between the rolls it is dried by suitable means, such as subjecting it to heated air in a drying oven.

A suitable liquid bath for carrying out my new process and securing the novel resulting fabric, comprises linseed oil mixed with asuitable drier, such as a linoleate of lead, cobalt, or manganese, and also with a suitable thinner, such as petroleum naphtha. The composition further carries in suspension a pigment, such as aluminum powder. The proportion of this powder employed may be'varied, depending on the color tones desired in the resulting fabric.

The fabric to be treated is preferably first dyed a selected color and I have found that if a red fabric is employed and treated with a liquid bath which carries aluminum powder as a pigment the resulting product has a very satisfactory appearance, having a grayish red tone on one side and a metallic gray tone on the other side. The side which was in contact with thesteel roll during treatment has, after drying, the grayish red tone, and while I do not bind myselfto any theory as to why the color of the side which passed Application filed February 23, 1929. Serial No. 342,300.

in contact with the rubber roll is different, it would appear from the resulting product that the metal pigment is distributed by the action of the rolls in such manner that it is much more. dense, or in other words, more of it visible, on the side which contacted with the rubber roll. The pressure applied to the fabric as it passed between the rolls may of course be varied but the desired and attractive resulting different appearances of the two sides of the fabric is secured when the pressure between the rolls is so adjusted as to remove the treatment liquid to such extent that the treated fabric when dried is not of appreciably greater thickness than prior to treatment.

Other pigments, such as bronze powder, for example, may be substituted for aluminum powder in the liquid bath, and by varying the color of the cloth treated and color of the pigment a variety of fabrics, as to color, may be produced, always, however, of different color on the opposite sides, and therefore of particular desirability for use in making unlined waterproof garments.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. The process of treating a fabric which comprises passing it through a liquid bath containing a metallic pigment, then passing the fabric between rolls one of which has a smooth rigid surface and the other a smooth resilient surface, and then drying the fabric.

2. The process of treating a colored fabric which comprises passing it through a bath of waterproofing material which contains a metallic pigment, passing the fabric between a pair of rolls one of which has a smooth rigid surface and the other a smooth resilient surface, and then drying the fabric.

3. The process of treating an absorbent textile fabric which comprises immersing it in a drying oil containing a metallic pigment, then passing the fabric in single sheet form between squeezing rolls, one of which has a smooth rigid surface and theother a smooth resilient surface, said rolls being adjusted to remove such portion of the treatment liquid as will result in the fabric having substantially the same thickness as before treatment, and then drying the fabric.

4. The process of Waterproofing and simultaneously imparting different appearance to 5 the opposite sides of a Woven absorbent cloth of red color which comprises immersing the cloth in a bath of liquid waterproofing material containing a metallic pigment of a color different from that of the cloth, and passing go the cloth in single sheet form between a pair of squeezing rolls, one of said rolls having a smooth rigid surface and the other a smooth resilient surface, whereby surplus treatment I material is removed and the pigment c0n tained in the treatment material remaining in the cloth is so distributed as to modify the original color of the cloth to a greater extent on one surface than on the other.

In testimony whereof, I hereunto afiix my signature, this 16th day of February, 1929.

JOHN E. GEORGE.
