County of Lancaster, Print Buyer, for the Invention. of "IMPROVEMENTS IN
TREATING FABRICS PRINTED WITH ANILINE COLOURS."
Scaled the 1st June 1877, and dated the 16th March 1877.
PROVISIONAL SPECIFICATION left by the said William Jackson at the
Office of the Commissioners of Patents on the 16th March 1877.

"IMPROVEMENTS IN TREATING FABRICS PRINTED WITH ANILINE
COLOURS."
My Invention consists in fastening and restoring aniline colours when printed
on woven fabrics. This Invention is particularly beneficial when applied to aniline
blacks, but it may be applied to other aniline colours.
A convenient mode of performing my Invention is as follows:-After the fabrics
have been printed with the aniline colour, they are passed through a solution of
soda and salt, and left to dry; this process fastens the colour effectually on the
fabric when applied immediately after printing, whereas when not so treated the
colours would fade on exposure to the air; and it restores and fastens the colour
if it has been allowed to fade from exposure.
My Invention may be modified by mixing the soda and salt with the aniline
colour or otherwise.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by

tember 1877.

COLOURS."

page_text: When fabrics have been printed with certain aniline colours, and particularly
with aniline blacks, it frequently if not always happens that the colours fade after
a few days' exposure to the atmosphere. Now, my Invention consists in so treating
fabrics printed with aniline colours, that the colours shall be made fast on the
fabrics, and that colours that have been allowed to fade by exposure shall, to a
great extent, be restored.
In performing my Invention immediately, or soon after the fabrics have been
printed with the aniline colours in the ordinary manner, they are passed through a
solution of carbonate of soda, or the ordinary soda of commerce, combined with
chloride of sodium, or the common salt of commerce, in the proportion of six ounces
of soda and one ounce of salt to one gallon of water, the fabrics are then dried, and
the aniline colours are by this means effectually fastened on the fabrics.
When fabrics printed with aniline colours have been allowed to fade by exposure
to the atmosphere, they may be restored by passing the printed fabrics through a
solution of the above description.
My Invention may be modified by mixing the soda and salt with the starch or
other ingredients employed for finishing the fabrics printed with aniline colours; or
the fabrics may be printed and finished in the ordinary manner, and then passed
through the solution above described to fasten or restore the aniline colours.
Having thus stated the nature of my Invention and described the manner of
carrying the same into practical operation, I wish it to be understood that I do not
intend to limit myself to the details or proportions given, and I claim the improved
mode of treating fabrics printed with aniliue colours, whereby the colours are
fastened or restored, as described.
In witness whereof, I, the said William Jackson, have hereunto set my hand
and seal, this Twelfth day of September, One thousand eight hundred
and seventy-seven.
WILLIAM JACKSON. (L.S.)
