WILLIAM WILKS BLACKETT of Leeds in the County of York
IN FINISHING TEXTILE FABRICS
"3
"IMPROVEMENTS,
The object of my invention is to produce textile fabrics, with a better finish,
handle solidity, appearance, durability, weight condition and strength than has
hitherto been obtained
The ingredients I use in obtaining the above results are preferably of a purely
mineral nature and are chiefly:-Chloride of Calcium; Chloride of Iron and White
Arsenic, other such ingredients may be added in some cases with advantage
according to the nature of the fabrics.
The ingredients are ground to powder and then by the addition of water are
separately reduced to a liquid condition by means of boiling; after each compound
part has been thus reduced to its liquid condition the different liquids are well
mixed together so forming the one liquid which at a proper temperature is applied
(by means of rollers placed in a trough) to the different textile fabrics and gives
the above results. Fabrics so finished are in no way detrimentally effected by
variation of temperature or other climatic conditions.

"IMPROVEMENTS
The object of my invention is to impart to textile fabrics, better finish, handle
solidity, appearance, durability, weight, and condition, than has hitherto been
obtained.
The ingredients I use in obtaining the above results are of a purely mineral
nature and chiefly :-Chloride of Calcium, Chloride of Iron, and White Arsenic in
various combinations according to the nature of the fabrics.
These ingredients are ground to a powder and then by the addition of water are
separately reduced to a liquid condition by means of boiling, after each component
part has been thus reduced to its liquid condition, the different liquids are well
mixed together, so forming the one liquid which at a proper temperature is applied
(by means of rollers placed in a trough) to the different textile fabrics and gives
the above results; fabrics so finished are in no way detrimentally effected by
variation of temperature, or other climatic conditions.
Such being the nature and object of this my said invention in order that the
same may be fully understood, I will proceed to describe the same in detail.
This invention relates to the finishing off all Textile Fabrics by the action of a
mixture of Chloride of Iron, Chloride of Calcium, White Arsenic and water or
some of them according to the fabrics, and their special requirements, by means of
which I impart to the various textile fabrics very considerable improvements over
all other methods of finishing hitherto in use, such improvements being in the
handle, solidity, appearance, durability weight and condition.
The ingredients I use in obtaining the above results are in the following
proportions.

page_text: effect,
would have it understood that what I claim as the invention to be secured
to me by the hereinbefore in part recited Letters Patent is,-
1 The finishing of textile fabrics in the manner described, and for the purposes
set forth.
2 The use and employment of Chloride of Calcium, Chloride of Iron, and White
Arsenic, separately or in combination, in the manner described, and for the purposes
set forth.
In witness whereof I the said William Wilks Blackett have hereunto set, my
hand and seal this ninth day of January in the year of our Lord one
thousand eight hundred and eighty three.
