ALEXANDER WINOGRADOEF, OF NEW YORK, N. Y., ASSIGNOR TO INECTO, INC., 01'

NEW YORK, N. Y., A CORPORATION OF DELAWARE.

ART OF DYEING FIBERS.

No Drawing.

My invention includes the use of iodine or any of its compounds capable of liberat ng iodine in an acid solution of the oxidizmg agent employed in connection with any proc- 5 ess of dyeing which depends upon the formation of dyestuif upon the fibers by combination of an oxidizing agent with a dye intermediate.

My invention is more particularly directed to an improvement in the art of dyeing fibers such as hair, fur, feathers and the like, with developing colors which are formed on the fibers by the action of an oxidizing agent such, for instance, as hydrogen peroxide, upon a dye leuco-compound such, for instance, as paraphenylene diamine.

- It has long been known that the speed of dyeing and the quality of the color produced in a developing bath may be greatly improved by the use of certain substances, such as heavy metal salts; for instance, copper acetate. The use of these metallic components is often objectionable for many reasons, particularly because of the injurious effect upon the hair texture. I do not wish to necessarily exclude the heavy metal salts but offer the iodide as an inoffensive alternate. An iodide of a heavy metal WOllld'bB capable of exerting a double effect partly due to the' iodide content and partly due to the heavy metal.

By my invention the speed of dyeing may be greatly increased and the uniformity of shade vastly improved without the use of objectionable salts or injurious oxidizing agents. I have found that the use of iodine containing materials, for instance, potassium iodide, cadmium iodide or lithium iodide will permit of this increase of speed of dyeing. The method of use may be either by mordanting the fibers in a preliminary bath, or by adding the iodine-containing material directly to the dye bath.

The mechanism of this action has not'been definitely determined but it is well known that iodides or iodine-containing materials act as catalysts in many types of reactions, and undoubtedly their role in this instance is likewise catalytic, because very smalldifference in speed of reaction.

Examples of the use of my invention are as follows:

The fibers are soaked for fifteen minutes in a solution containing ten parts by weight Application filed July 11,

of cadmium iodide in one hundred parts of solution. The fibers are then washed with water and treated with the appropriate mixture of pharaphenylene diamine and hydrogen peroxide for from ten to fifteen minutes, depending upon the depth of shade desired. The fibers are then washed and dried.

.Another method would be to add an iodide to the dye bath containing a mixture of paraing an iodide to a solution of paraphenylene diamine and soaking the material to be dyed therein. The material is then washed and treated with an oxidizing agent, such as hydrogen peroxide, whereupon the color will be developed.

What I claim is 1. In the art of dyeing fibers, treating the fibers with a solution of an inorganic iodide where the color is developed by the oxidation of a leuco-compound.

2. In the art of dyeing fibers, treating the fibers with an oxidizing agent and a dye leuco-compound in the presence of a solution of .an iodine-containing material.

3. In the art of dyeing fibers, treating the fibers with an oxidizing agent and a dye leuco-compound in the presence of a solution of an iodide.

4, In the art of dyeing fibers, treating the fibers with an iodine-containing material capable of liberating iodine from an acid solution when treated with an oxidizing agent, in such a way as to promote the development of dyestufis formed by oxidation upon the fibers.

5. In the art of dyeing fibers, treating the fibers with an iodide in a solution, in such a way as to promote the development of a dyestufl upon the fibers by oxidation.

6. A'process for the rapid development of dye upon fibers, by oxidation of a dye leucocompound in the presence of an iodine-containing material.

- 7. A process for dyeing fibers by using an oxidizing agent and a dye leuco-compound, in conjunction with an iodine-containing material.

8. A process for dyeing fibers, by developing the dye upon the fibers by oxidation of a dye leuco-compound in the presence of an iodine-containing material.

' 9. A process for preparing fibers for dyeing with colors developed by oxidation, by impregnating the fibers With a solution-0f an iodine-containing material.

as my invention, I have signed my name this 9th day of July 1925. i DR. AL EXANDER WINOGRADOFF.
