    N° 6747 A.D. 1894 Date of Application, 4th Apr., 1894 Complete Specification Left, 4th J?n., 1895—Accepted, 16th Feb., 1895 PROVISIONAL SPECIFICATION. An Improved Mode of Rendering- Fabrics Impervious to Infection. I Helene Rachel Hirschler of 3 Place Victor Hugo, Paris in the Republic of France, married, do hereby declare the nature of this invention to be as follows :— The object of this invention is to render clothes and other fabrics impervious to 5 infection, and in such a manner that they will stand washing without detriment to the antiseptic properties with which they have been provided, and the invention consists in impregnating the fabric, whether of silk, wool, cotton, or other material, with an antiseptic substance constituting a microbicide, which is absolutely inoffensive, and without odour, and which will withstand the action of soaping, ■RJ without which property the impregnated fabric wTould lose its antiseptic properties. Up to this date, no one has succeeded in fixing an antiseptic substance in fabrics, especially so with respect to flannel, because it is absolutely necessary to find a substance which is rendered insoluble and becomes incorporated, so to speak, in the 15 fibre of the fabric. In carrying out this invention, the fabric is first impregnated with a solution of a soluble salt of bismuth, say the nitrate of bismuth, acidified with acetic acid or otherwise. After a sufficient mordanting in this metallic solution, the fabric is well rinsed 20 previous to being passed through a hot bath containing a solution of salicylic acid, or a soluble salicylate, or, it may be, bromic or iodo-salicilic acid, or one of their soluble salts, or benzoic or cresotinic acid, or, in a word, any other antiseptic acid or antiseptic salt capable of forming an insoluble salt of bismuth on the fibre. Dated this 3rd day of April 1894. 25 NEWTON & SON, Agents for the Applicant. COMPLETE SPECIFICATION. An Improved Mode of Rendering Fabrics Impervious to Infection. I Helene Rachel Hirschler of 3 Place Victor Hugo, Paris in the 30 Republic of France (married), do hereby declare the nature of this invention and in what manner the same'is to be performed, to be particularly described and ascertained in and by the following statement : — The object of this invention is to render garments, fabrics, or tissues, impervious to infection, and the invention consists in impregnating the garments, fabrics, or 35 tissues, with a substance which is antiseptic, an absolutely inoffensive microbicide, and without odour, and which will allow ot the garments or other fabrics being washed continuously without losing their antiseptic properties. Up to this date, no one has succeeded in fixing an antiseptic substance in a fabric, and especially so with respect to flannel, because no one has been able to 40 find an antiseptic which can be rendered insoluble, and becomes, so to speak, incorporated in the fibres of the fabric.
