Process for Dyeing Textile Materials in Cops or Spools with
Alizarine and other Mordant Dyes.
I, OLIVER IMRAY, of No. 28 Southampton Buildings, Chancery Lane, in the
County of London, Chartered Patent Agent, do hereby declare the nature of this
invention to be as follows:-
The dyeing mechanically of textile materials in cops or spools has hitherto been
only possible with colouring matters soluble in water, the insoluble mordant dyes
such as alizarine not being capable of use in this way.
My foreign correspondents have now succeeded in dyeing with these dyes on
cops and spools by using them in the form of alkaline solutions.
Of the colouring matters at present known and commercially used, the following
are adapted for this purpose:
Alizarine, purpurine, anthra- and flavo-purpurine, alizarine brown, rufigallol.
Nitro alizarines (alizarine oranges).
Amido alizarines (alizarine maroon, claret).
Alizarine bordeaux, alizarine cardinal.
Alizarine cyanines, anthracene blues.
Alizarine cyanine black.
Alizarine black (M. L. & B.) naphtazarine.
Alizarine green, alizarine yellow (ellag acid gallacetphenon, benzophenon, and
similar products, azo colours from nitraniline and salicylic acid).
Galloflavin, anthracene yellow, flavazol, anthracene red, diamant yellow, diamant
flavine, diamant orange, cloth orange and cloth brown, as well as some dyes which
contain salicylic acid, such as: oriol, cotton yellow, chrysamine, kresotine yellow,
diamine yellow, Hessian yellow, carbazol yellow.
Azarine, azo green, Persian red.
Solid green, dioxine, gambines.
Roseline, galleine, ceruleine.
Gallocyanine, gallamine blue, gallanilid blue, bleu fava, delphin blau, azurine in
paste, gallanil blue, gallanil violet, celestine blue.
Chrome blue, chrome violet, chrome green, chrome yellow, chrome orange,
chrome bordeaux, chrome prune, chrome red, chrome rubine, chrome brown,
chrome black.
The process is effected as follows.
The cops, spools, bobbins &c. are impregnated with a solution of the colouring
matter to be used mixed with an alkaline medium such as ammonia, hydroxydes
and carbonates of alkalies, carbonate of ammonia, alkaline reagent salts, such as
phosphate of soda, borax, silicate of potash, aluminate of sodium, alkaline reagent
soaps, Turkey red oil, and organic bases (for instance amines).
The fugitive mediums employed have the advantage over the fixed alkalies and
those containing salts, that in the drying they evaporate and leave the colouring
matter insoluble on the fibre, whereas, when fixed alkalies are employed, it remains
soluble.

page_text: Besides the solution of colouring matter there may be added to the dye bath
substances which do not precipitate the colouring matter in an alkaline solution, as
for example aluminate or stannate of sodium, solution of oxide of zinc and of lead
in soda lye, solutions of ammonia, of chrome and copper oxide, cobalt, nickel or
manganese oxydul, red and yellow prussiate of soda, chromic salts, solution of soap,
Turkey red oil, glycerine &c.
After impregnating the fibre, the excess of liquid is removed by centrifugal
machine, vacuum, or otherwise, and the material is then dried for fixing purposes;
a short steaming will have the same effect.
The dried material is then impregnated with the mordant in a bath, containing
the necessary mordants (alumina, chrome, lime, iron &c.) best in the shape of salts
of a volatile acid, such as acetic acid; the excess is removed, and after, or without
drying the formation of the colour lake can then be effected and completed by
steaming.
Washing, soaping and clearing serve in many cases to increase the brightness of
the dye.

I, OLIVER IMRAY, of No. 28 Southampton Buildings, in the County of
London, Chartered Patent Agent, 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:-

9-475 gall. water
0-250 gall. acetic acid 12° Tw. 1: 10.
00-250 gall. acetate of iron 15° Tw.
0-025 gall. acetate of lime 28-4° Tw.
The manipulations are the same as described for pink.
By combination of several colouring matters in the first bath and of the different
mordants, a great number of colours may be obtained.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The herein described process for dyeing textile materials in cops and spools with
alizarine and other mordant dyes by impregnating the material with the alkaline
solution of the colouring matter, drying or steaming and afterwards treating it
with the necessary mordants and effecting the development of the colour lake by
steaming.
