HELENE RACHEL HIRSCHLER, OF PARIS, FRANCE, ASSIGNOR TO J. HAYEM dz CO., OF SAME PLACE.
IMPREGNATlNG FABRICS WITH ANTISEPTIC SALTS.
SPECIFICATION forming part of Letters Patent No. 564,928, dated uly 28, 1896.
Application filed April 6, 1895. Serial No. 544,803. (No specimens.) Patented in France liovember 26, 1893, No. 234,161; in England April 4,1894, No. 6,747, and in Germany April 29, 1894, No. 77,880.
To all whom it may concern: cresotinic acids or their combinations. In a Be it known that I, HELENE RACHEL word, any other antiseptic acid or salt capa- HIRSCHLER, of Paris, in the Republic of ble of forming on the fiber an insoluble salt France, have invented an Improved Mode of of the metal used may be employed.
Rendering Fabrics Impervious to Infection, The first bath containing the metallic salt 5 5 (for which I have obtained a patent in France, to form the mordant base or support is predated November 26,1S93,No. 234,161; in Gerpared from the following ingredients, the many, dated April 29, 1894, No. '7 7 ,880, and in quantities of which are calculated for the Great Britain, dated April 4, 1894, No. 6,747,) treatment of about ten kilograms of fabric:

One hundred and twenty-five to one hundred 60 The object of this invention is to render and fifty grams nitrate of bismuth or one garments,fabrics, or tissues impervious to in hundred and twenty-five grams chlorid or fection; and theinvention consists in impregbichlorid of tin dissolved in two hundred hating the garments, fabrics, or tissues with to two hundred and fifty grams crystalliza substance which is antiseptic and an abable acetic acid, Warm.

The effect Which takes place on bring- In carrying out this invention the fabric ing the salicylic acid into the presence of the is first treated with a lukewarm solution of metallic salt is to produce an insoluble salia metallic salt, which acts as a kind of morcylate of bismuth or tin, as the case may be,

The fabric is then. removed, and after rinsing is passed through a second bath containing in tannic acid two per cent. of the weight of the fabric under treatment. The fabric is again removed and rinsed and finally passed through a third bath, containing a solution of three per cent. of salicylic acid and Solvays soda in the proportion of an eighth part by weight of the acid used.
The fabric should be left in each bath about half an hour. The temperature of the tin bath and of the salicylic-acid bath should be raised to boiling-point, the temperature of the second bath being, preferably, that of warm Water.
Although I have mentioned garments and fabrics or tissues only, the invention is' applicable to vegetable or animal fibers generally, such as used, for example, for mattresses or bedding, or stuffing for articles of furniture, or feathers used for pillows, or to down for quilts, or for any other materials or sub stances which are liable to become infected with microbes or germs of diseases, all of which, for the purposes of this invention, 1 include under the word fabrics.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- The mode of rendering fabrics impervious to infection as herein described, consisting in impregnating the fabric with a-solution of a metallic salt, such as chlorid of tin, and subsequently immersing the so-impregnated fabric in a solution of an organic acid, such as salicylic acid, as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
