IMPROVEMENTS IN DYEING AND PRINTING SILK AND OTHER WOVEN FABRICS
Year: 1873

page_text: LETTERS PATENT to William Whiston, of Langley, near Macclesfield,
in the County of Chester, for the Invention of "IMPROVEMENTS IN
DYEING AND PRINTING SILK AND OTHER WOVEN FABRICS."
Sealed the 14th November 1873, and dated the 24th September 1873.
PROVISIONAL SPECIFICATION left by the said William Whiston at the
Office of the Commissioners of Patents, with his Petition, on the
24th September 1873.
I, WILLIAM WHISTON, of Langley, near Macclesfield, in the County
of Chester, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN DYEING AND PRINTING SILK AND OTHER WOVEN FABRICS," to be
as follows:-
This Invention relates to a combination of what is known as "hot
wax printing" with the process of dyeing silk or other fabrics with
aniline colors, whereby I am enabled to obtain white or colored spots or
other patterns upon a colored ground.
For producing white spots or other patterns on a colored ground I
print the spots or design upon white silk or other fabric by the well-

page_text: known process called "hot wax printing." I then dye the fabric the
desired aniline color in cold water (instead of hot as usual), and the
spots or pattern printed, as above described, will resist the dye.
For dyeing cotton or linen fabrics the ordinary mordants for aniline
colors must be employed.
After the cloth is dyed the required shade and dried I pass it through
a bath of benzine, benzoline, benzole, or other spirit obtained from coal
tar or petroleum, and this process removes the wax-from the cloth,
leaving the spots or pattern clear white without injuring the brilliancy
of the color.
When colored spots or patterns are required I first dye the fabric the
color of the spots or pattern, and when dried I print on the wax. I
then dye the cloth the ground color (in cold dye), which must be such a
shade as will cover the former dye, and after again drying the fabric pass
it through the benzoline or other coal tar or petroleum spirit to remove
the wax as before.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
.filed by the said William Whiston in the Great Seal Patent Office on
the 24th March 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WHISTON, of Langley, near Macclesfield, in the County of Chester, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of September, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Whiston, Her special license
that I, the said William Whiston, my executors, administrators, and
assigns, or such others as I, the said William Whiston, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
•

page_text: Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
DYEING AND PRINTING SILK AND OTHER WOVEN FABRICS," upon the condition
(amongst others) that I, the said William Whiston; my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said William Whiston, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement (that is to say) :-
This Invention relates to a combination of what is known as "hot
wax printing" with the process of dyeing silk or other fabrics with
aniline colors, whereby I am enabled to obtain white or colored spots or
other patterns upon a colored ground.
For producing white spots or other patterns on a colored ground I
print the spots or design upon white silk or other fabric by the well-
known process called "hot wax printing." I then dye the fabric the
desired aniline color in cold water (instead of hot as usual), and the
spots or pattern printed, as above described, will resist the dye.
For dyeing cotton or linen fabrics the ordinary mordants for aniline
colors must be employed.
After the cloth is dyed the required shade and dried I pass it through
a bath of benzine, benzoline, benzole, or other spirit obtained from coal
tar petroleum, and this process removes the wax from the cloth, leaving
the spots or pattern clear white without injuring the brilliancy of the
color.
When colored spots or patterns are required, I first dye the fabric the
color of the spots or pattern, and when dried I print on the wax. I then
dye the cloth the ground color (in cold dye) which must be such a shade
as will cover the former dye, and after again drying the fabric pass it
through the benzoline or other coal tar, or petroleum spirit to remove
the wax as before.

page_text: Having now described the nature and object of my said Invention,
together with the manner in which the same is to be or may be per-
formed or carried into practical effect, I wish it to be understood that I
claim as my Invention, the production of white or colored spots, or other
patterns upon a colored ground by the combination of the process
known as "hot wax printing" with the process of dyeing with aniline
colors, substantially in the manner herein-before described, that is, by
first printing the spots or design upon a white or colored fabric by hot
wax printing, then dyeing the fabric the desired aniline color in cold
water, and afterwards dissolving out the wax by a bath of benzine or
other suitable hydrocarbon spirit.
In witness whereof, I, the said William Whiston, have here-
unto set my hand and seal, this 23rd day of March, in the year
of our Lord, One thousand eight hundred and seventy-four.
