FAST DYEING ON THE FIBER.
IEO Drawing. Application filed October 12, 1925, Serial No. 62,149, and. in Germany September 27, 1924.
A known method of producing fast dyeings on the fiber consists in impregnating the fiber with a compound adaptedto be coupled and then treating the fiber with a solution of a diazo compound. In cases in which the compound adapted to be coupled has a certain afinity for the fiber it is suificient merely to wring out the impregnated fiber and to conduct the coupling without previously drying. in producing printed colors, the material is previously prepared with a compound adapted to be coupled, such as for example 2-onynaphthalene, and is printed with a thickened diazo-solution; or the material may be printed with a mixture of 'an alkali compound of 2-oxynaphthalene and stable diazo compound, after which the material is steamed or exposed to the air and theddyeing developed by treatment with an em In the known process dificulties are associated with the diazotization. By the present invention these diiiiculties are avoided and the process is conducted very simpl by carrying out the preparation of the diazo compound on the fiber where it unites directly with the coupling component. The preparation of a diam-solution or the use of agstable diazo compound is accordingly unnecessary.
One method of carrying out the invention consists in impregnating the fiber with a solution containing a nitrite and a compound adapted to be coupled and after wrlnging the damped goods treating them with a solution of a salt of a diazotizable base. The solution of this saltmay contain an excess of acid and a metal salt may be added to it if desired.
In pirinting, the goods may be printed with. a thic ened mixture of both components to om. 00.01;. coon:
gether with a nitrite and after drying the goods the dyestufi may be developed by action of an acid or of an acid salt. The print-- mg colours are characterized by their high' duction of azo dyes on the fiber may be combined with dyeing with any suitable dyes, whereby any desired mixed shades may be obtained.
The new process is also of interest in connection with art industries, such astor example painting materials by hand or by means of a stencil. I

The yarn is wrung and then introduced into 200 com. of a solution containing0.95 grams of the hydrochloride of 2.5 dichloraniline and 7.5 rams of aluminium sulphate per liter. The dyeing obtained is reddish orange.

35 by treatment with a soluble nitrite and a reagent having an acid reaction, of a diazotizable amine on the fiber in the presence of a compound adapted to be coupled, the steps which consist in impregnating the fiber with a mixture comprising the compound adapted to be coupled and the soluble nitrite, and, thereafter, treating the so-impregnated fiber with a second mixture comprising the reagent having an acid reaction.
2. In the process of producing fast dyeings on cellulose acetate fiber involving the ing the fiber from said bath, wringing the fiber, and developing the dyeing on the soimpregnated and wrung fiber by treatment of the same in a second bath comprising a reagent having an acid reaction.
