Yarns and Fabrics Composed thereof.
We JOHN HENRY GARTSIDE of 56 Fountain Street Manchester in the County of
Lancaster Manufacturer and Merchant and JONATHAN BARNES of Buckton Vale near
Stalybridge in the County of Chester Chemist do hereby declare the nature of this
invention to be as follows:-
Our invention relates to and consists in dyeing cotton, cotton yarn and cotton textile
fabrics and other vegetable fibres and yarns and fabrics composed thereof with the
shades of drab, fawn and other similar colours or shades known as "Khakee" so that
such shades or colours shall be "fast."
In carrying our invention into effect we operate upon clean, unbleached or bleached
cotton or other vegetable fibre unbleached or bleached yarn or thread formed of cotton
or other vegetable fibre or unbleached or bleached textile fabric composed of cotton or
other vegetable fibre all of which materials we shall hereinafter refer to as "the
material to be operated upon." We take the material to be operated upon and immerse
it for a suitable length of time in a solution of any suitable kind of tannin matter which
solution of tannin matter is made to correspond in strength with the depth or degree
of shade or colour required. After immersing the material to be operated upon for a
suitable length of time in the solution of tannin matter aforesaid we remove the
material to be operated upon from the said solution and exhaust or remove the super-
fluous portion of the aforesaid solution of tannin matter from the material to be operated
upon and afterwards subject the material to be operated upon to the action of a dilute
solution of any suitable compounds of iron and chromium for a suitable length of time.
We next wash in water the material to be operated upon and then subject the material
to be operated upon to the action of a boiling solution of bichromate of potash or of
bichromate of soda until the shade or colour upon the material to be operated upon is
unalterable and again wash in water the material to be operated upon. We next boil
the material to be operated upon in a solution of carbonate of soda until the shade or
colour of the material to be operated upon undergoes no change. The material to be
operated upon is then washed in water and dried and afterwards finished in any
suitable manner.

Yarns and Fabrics Composed thereof.
We JOHN HENRY GARTSIDE of 56 Fountain Street Manchester in the County of
Lancaster Manufacturer and Merchant and JONATHAN BARNES of Buckton Vale
near Stalybridge in the County of Chester Chemist 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 :-
Our invention relates to and consists in dyeing cotton, cotton yarn and cotton textile
fabrics and other vegetable fibres and yarns and fabrics composed thereof with the
shades of drab, fawn and other similar colours or shades known as "Khakee" so that
such shades or colours shall be "fast."
In carrying our invention into effect we operate upon clean, unbleached or bleached
cotton or other vegetable fibre unbleached or bleached yarn or thread formed of cotton
or other vegetable fibre or unbleached or bleached textile fabric composed of cotton or
other vegetable fibre all of which materials we shall hereinafter refer to as the
"material to be operated upon." We take the material to be operated upon and
immerse it for a suitable length of time in a solution of any suitable kind of
tannin matter such as sumac extract which solution is made of a strength of
about 2° Twaddle. Such solution is made to correspond in strength with the
depth or degree of shade or colour required. After immersing the material to be
operated upon for a suitable length of time in the solution of tannin matter afore-
said we remove the material to be operated upon from the said solution and exhaust
or remove the superfluous portion of the aforesaid solution of tannin matter from
the material to be operated upon and afterwards subject the material to be operated
upon to the action of a dilute solution of iron and chromium. In order to form
such solution of iron and chromium we make a solution of nitrate of iron at or
about 20 Twaddle and make a solution of acteate of chromium at or about
3° Twaddle. We then mix the solutions of nitrate of iron and acetate of chromium-
We next wash in water the material to be operated upon and subject the material to be
operated upon to the action of a boiling solution of bichromate of potash or of bichromate
of soda, using a quantity of bichromate of potash or bichromate of soda equal in weight to
about three to four per cent. of the weight of the material operated upon.
practice that by adding sulphuric acid to the bichromate of potash or bichromate

of soda solution in a quantity sufficient to liberate nearly the whole of the chromic
acid contained in such bichromate of potash or bichromate of soda solution the action
of the chromic acid in such solution is rendered much more rapid. We immerse
the material to be operated upon in either of the solutions until the colour is
unalterable and again wash in water the material to be operated upon.
boil the material to be operated upon in a solution of carbonate of soda, such

to about five per cent. of the weight of the material to be treated.
We boil the
material in such solution of carbonate of soda until the shade of colour of the
material to be operated upon undergoes no change. The material to be operated
upon is again washed in water and dried and we afterwards subject the material
operated upon to the action of steam. The material operated upon is afterwards
finished in any suitable manner.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what we
claim is :-
The above described process by means of which we are enabled to dye cotton, cotton
yarn, and cotton textile fabrics and other vegetable fibres and yarns and fabrics
composed thereof with the shades of drab, fawn and other similar colours or shades
known as "Khakee" so that such shades or colours shall be "fast."
