T 0 all whom it may concern:
Be it known that I, CLARENCE L. COLE, major,United States Army, a citizen of the United States, residingat Fort Logan H. Roots. in the county of Pulaski and State of Arkansas, have invented certain new and useful Improvements in Methods of Dyeing and Preserving Fabrics, of which the following is a specification.
This invention relates to preserving fabrics from the action of mildew and like organic growths, and the general object of the invention is to provide a method which will protect canvas, yarns, or other textile" fabrics from the action of mildew by forming copper tannate in the canvas.
A further object of the invention is to provide a method of protecting canvas from destruction by the effects of mildew which is very simple and which has been tested and found thoroughly effective.
It is a well known fact that copper is destructive to the life of algae and fungi, which are low forms of life present in stagnant pools and in moisture, and, therefore, it is the design of this invention to provide means whereby canvas, yarns, or other textile fabric may be impregnated with copper. I have found, by experiment, and proved by thorough tests that by using tannic acid and copper sulfate, 2. chemical combination, copper tannate results, which renders the textile fabric so treated entirely immune to the action of mildew. I have further found that not only does this copper tannate have a destructive effect upon these low forms of life, but that it colors canvas or like material, producing indeed a khaki color, which is particularly valuable where the canvas is to be used for making tents and other shelters.
The method. is as follows :-The yarn, canvas, or tent cloth is immersed in a cold solution of water and 2% of,tannic acid, (3, 11, 0 .The temperature of the solution is then raised to 190 F. and the solution then allowed to cool. When the solution is cooled, the yarn, canvas, or tent cloth is immersed in a bath formed by suspending 65% of calcium carbonate in a 5% solution of copper sulfate. The textile fabric is allowed to remain in this solution until a com lete reaction has occurred. The cloth is t en removed from the solution and thoroughly washed to remove the deposited Specification of Letters Patent.

carbonate and then dried. lVhen dry, the previously white canvas cloth or yarn has acquired a khaki color.
When cloth which has been previously impregnated with a solution of tannic acid is placed in the sulfate of copper bath. two distinct chemical reactions take place, one
betweenthe copper ion and the tannate. radical, and the other between the calcium of mold growth or apparent deterioration in tensile strength. As tannic acid is a common mordant used in dyeing, the copper tannate produces a fast color and hence the method above described is particularlyserviceable as a dye for yarn and in the manufacture and treatment of cotton fabrics.
It will further be noted that the method above described produces no poisonous effects which would be injurious to mill operatives in treating the canvas in the bolt or in treating the yarn previous to Weaving the canvas.
It may be said that this method has been carefully tested by Army ofiicials detailed for this purpose and has been found to he of particular value. It is also to be understood that the term fabric as used in this specification and claims is intended to include not only a woven fabric, but the yarn, threads, or other elements of which the fabric is composed.
The action of the tannic acid is that of a mordant, and the copper ions combine with the tannic acid to form an insoluble compound the primary dye, copper tannate, which preserves the canvas through the inhibitary action ofthe copper on low forms of life, such as molds which it destroys.
While the tannic acid and copper sulfate are in all cases used, yet I have also found that the addition of potassium dichromate gives a different shade to the fabric. I have also found that boiling the fabric with a acid and subsequently immersing the fabric,
in a bath formed by suspending an excess of calcl'um carbonate in a solution of copper sulfate.

4. The method of treating textile fabrics to preserve them, consisting in first immersing the fabric in ,a solution containing tannic acid and subsequently immersing the fabric in a bath formed by suspending calcium carbonate in a 5% solution of sulfate, the calcium carbonate being in excess in the bath.
5. The method of preserving textile fabrics, consisting in immersing the fabric in a cold solution of Water and tannic acid, heating the solution and subsequently permitting the solution to cool, and withdrawing the fabric from the solution and immersing the same in a bath formed by suspending calcium carbonate in a solution of copper sulfate.
