An Improvement in yo
I, THOMAS INGHAM, of 4, York Street, Manchester, in the County of Lancaster,
Manufacturing Chemist, do hereby declare the nature of this invention to be as
follows;
1
This invention relates especially to the process of dyeing for which Letters
Patent No. 1,629 were applied for by myself on the 21st day of January 1897,
and the object of this invention is to render such process more perfect when dyeing
goods requiring subsequent treatment, similar for example to the treatment to
which cotton velvets are subjected after dyeing.
I have found that goods dyed by my process above described and requiring to.
undergo subsequent treatment as above described have not as good and bright
an appearance a as goods dyed thereby and not so treated; and the object of this
invention is to avoid this deterioration in brilliancy or bloom.
For this purpose I mix with the developing bath a suitable quantity of an aniline
or coal tar color, such quantity and color varying according to the shade desired,
and I find that goods passed through my logwood bath and then through a develop-
ing bath mixed with aniline or coal tar color retain their bloom after the
subsequent softening or other process.
This invention will therefore avoid the necessity of any special process or bath
for applying the aniline bloom to the goods.

I, THOMAS INGHAM, of 4, York Street, Manchester, in the County of Lancaster,
Manufacturing Chemist, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement;
This invention relates especially to the process of dyeing for which Letters
Patent No. 1,629 were applied for by myself on the 21st day of January 1897,
and the object of this invention is to render such process more perfect when dyeing
goods requiring subsequent treatment, similar for example to the treatment to
which cotton velvets are subjected after dyeing.

page_text: I have found that goods dyed by my process above described and requiring to
undergo subsequent treatment as above described have not as good and bright
an appearance as goods dyed thereby and not so treated and the object of this
invention is to avoid this deterioration in brilliancy or bloom.
For this purpose I mix with the developing bath (that is to say the mordant
bath) a suitable quantity of an aniline or coal tar color (say in the proportion
of oz. to 1 oz. of the coal tar color to the gallon of mordant) such quantity and
color varying according to the shade desired, and I find that goods passed through
ny logwood bath and then through a developing or mordant bath mixed with
aniline or coal tar color retain their bloom after the subsequent softening or other
process.
This invention will therefore avoid the necessity of any special process or bath
for applying the aniline bloom to the goods.
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 improved dyeing process consisting in first passing the yarn or cloth through
the coloring bath in the open state, and suitably squeezing the same between
rollers and then passing the same into the mordant or fixing solution in the cold
state. (this mordant bath being prepared by adding thereto a suitable proportion
of an aniline or coal tar color) and afterwards steaming the same, which effects the
combination between the coloring matters and the mordant thereby producing a
brilliant and permanent color, substantially as herein before set forth.
Dated this 5th day of August 1898.
