Improvements in Printing Calico and other Woven Fabrics of
Cotton and Cotton Warps.
We, LOUIS RIVETT, of Norfolk House, Heaton Norris, Stockport, in the
County of Lancaster, Cotton Manufacturer, and ROBERT HENRY SCOTT, of Gale
House, Littleborough, in the County of Lancaster, Calico Printer, do hereby
declare the nature of this invention and in what manner the same is to he
performed, to be particularly described and ascertained in and by the following
statement:
This invention consists in the combining or printing at one operation and in
the manner requisite in each particular case on calico or other woven fabrics of

page_text: cotton or cotton warps subjected to what is known as "the naphthol prepare" of
a colour or colours or colouring substance or substances of the paranitraniline
series or nitrosamine red along with black, blue, green or yellow which may be
suitable for use with "a naphthol prepare" and thus enables us to obtain by cheap
and simple means effects and combinations of a colour or colours or colouring
substance or substances of the paranitraniline series or nitrosamine red with black,
blue, green and yellow, or one or more of them.
The colours or colouring substances which we use in connection with a colour
or colours or colouring substance or substances of the paranitraniline series or
nitrosamine red are lead yellow, Prussian blue and green produced by the mixture
of lead yellow and Prussian blue. Acids or other reagents are added to the
colours or colouring substances in order to neutralise or otherwise act upon the
"naphthol prepare as may be requisite.
After calico or other woven fabrics of cotton or cotton warps have been printed
according to this invention with the colours or colouring substances to be applied
thereto such calico or other woven fabrics or warps are subjected to the treatment
necessary to fix or develop the colours upon such calico or other woven fabrics
or warps and then washed or treated as may be necessary or desirable.
In order that our invention may be readily carried into effect we will now
further describe the manner in which our invention is applied in the printing of
calico and other woven fabrics of cotton and cotton warps.
The blue to be printed upon calico and other woven fabrics of cotton or cotton
warps according to our invention is produced by printing thereon Prussian blue in
connection with oxalic acid or tartaric acid or both oxalic acid and tartaric acid,
or other acid or acids.
As an instance of the proportions in which we may mix together the materials
to be printed upon calico and other woven fabrics of cotton or cotton warps in
order that a blue may be produced thereon in accordance with our invention and
as an instance of the manners in which such materials may be mixed together we
would mention that two and a quarter pounds of Prussian blue in the form known
as prussiate pulp, two and a half pounds of oxalic acid and one quart of hot water
being mixed together and five pounds of tartaric acid and three pints of water
being mixed together and one quart of water being thickened by being mixed
with one and a half pounds of starch, the three mixtures so produced may be all
mixed together and the mixture so produced may be printed upon the calico or
other woven fabric of cotton or cotton warp to be operated upon.
°
The yellow to be printed upon calico and other woven fabrics of cotton or
cotton warps according to our invention is produced by printing thereon acetate
or nitrate of lead in connection with any suitable acid such for instance as tartaric
acid.
As an instance of the proportions in which we may mix together the materials
to be printed upon calico and other woven fabrics of cotton or cotton warps in
order that a yellow may be produced thereon in accordance with our invention
and as an instance of the manners in which such materials may be mixed together
we would mention that five pints of water being used to dissolve four pounds of
nitrate of lead, three pounds of citric acid and three pounds of tartaric acid, and
two and a half pints of water being thickened with one and a half pounds of
flour, the solution of nitrate of lead and citric and tartaric acids and the mixture
of flour and water may be mixed together and the mixture so produced may he
printed upon the calico or other woven fabric of cotton or cotton warp to be
operated upon.
The green which we print upon calico or other woven fabrics of cotton or cotton
warps is produced by a mixture of the blue and the yellow which are produced
in the manner above described.
As an instance of the proportions in which we may mix'together the materials
to be printed upon calico and other woven fabrics of cotton or cotton warps in
order that a green may be produced thereon in accordance with our invention and

page_text: as an instance of the manners in which such materials may be mixed together we
would mention that two parts of the mixture which we have above described as
being capable of being printed upon calico or other woven fabrics of cotton or
cotton warps in order that a blue may be produced thereon and one part of the
mixture which we have above described as being capable of being printed upon
calico or other woven fabrics of cotton or cotton warps in order that a yellow may
be produced thereon may be mixed together and the resulting mixture may be
printed upon the calico or other woven fabric of cotton or cotton warp to be
operated upon.
The black to be printed upon calico and other woven fabrics of cotton or cotton
warps according to our invention is formed from logwood liquor, gall liquor,
prussiate of potash and any salt of iron as may be convenient.
As an instance of the proportions in which we may mix together the materials
to be printed upon calico and other woven fabrics of cotton or cotton warps in
order that a black may be produced thereon in accordance with our invention and
as an instance of the manners in which such materials may be mixed together we
would mention that two gallons of logwood liquor may be mixed with three
gallons of gall liquor and one gallon of the resulting mixture may be mixed with
four ounces of yellow prussiate of potash and one and a quarter pounds of flour
and with six parts by volume of the mixture of gall liquor, logwood liquor, yellow
prussiate of potash and flour there may be mixed one part by volume of nitrate
of iron and the resulting mixture may be printed upon the calico or other woven
fabric of cotton or cotton warp to be operated upon.
The variations which it may be necessary to make in the intensity of the tints
or shades to be produced upon calico or other woven fabrics of cotton or cotton
warps according to our invention may be produced by varying the strengths of
the mixtures printed upon the calico or other woven fabrics of cotton or cotton
warps as may be requisite.
The calico or other woven fabric of cotton or cotton warp to be printed
according to our invention is first thoroughly bleached and is then " prepared
with naphthol or any other preparation of naphthol. After being prepared
with naphthol or any other preparation of naphthol the said calico or other
woven fabric of cotton or cotton warp is printed with the blue, yellow, green and
black above mentioned as being employed according to our invention or one or
more of them as may be desirable in each particular case and also with para-
nitraniline, the paranitraniline being prepared in the usual way for application to
the calico or other woven fabric of cotton or cotton warp. The printing of the
said calico or other woven fabric of cotton or cotton warp with paranitraniline and
the other or others of the above named colours to be applied to it is accomplished
by means of the ordinary machines or appliances used in the printing of calico or
other woven fabrics of cotton and cotton warps.
After the printing of the paranitraniline and the other colour or colours to be
used in connection therewith upon the said calico or other woven fabric of cotton
or cotton warp has been accomplished such calico or other woven fabric of cotton
or cotton warp may be run through a solution of bichromate of potash or
bichromate of soda in order that the colours may be fixed and developed upon such
calico or other woven fabric of cotton or cotton warp and then such calico or
other woven fabric of cotton or cotton warp may be washed and otherwise treated
as may be desirable.
In conjunction with or instead of paranitraniline we may employ any other
colour or colours of the paranitraniline series or nitrosamine red.
By combining and printing at one operation as above described upon calico or
other woven fabrics of cotton or cotton warps subjected to what is known as
"the
naphthol prepare a colour or colours or colouring substance or substances of
the paranitraniline series or nitrosamine red along with black, blue, green and
yellow which may be suitable for use with a "naphthol prepare
" or any one or
more of them we are enabled to obtain by cheap, simple and efficient means

page_text: effects and combinations of a colour or colours or colouring substance or substances
of the paranitraniline series or nitrosamine red with black, blue, green and yellow
or one or more of them and also to obtain by simple and cheap means effective
results in the printing of calico and other woven fabrics of cotton or cotton warps
and also to dispense with steaming of the calico er other woven fabrics of cotton
or cotton warps after the printing thereof and to obtain on calico or other woven
fabrics of cotton and cotton warps colours which shall be less liable to injury by
sunlight than the colours hitherto printed upon such goods.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
-claim is :-
The hereinbefore described improvements in printing calico and other woven
fabrics of cotton and cotton warps according to which for the purposes and
substantially in the manner herein before described there are combined and printed
at one operation and in the manner requisite in each particular case on calico
or other woven fabrics of cotton or cotton warps subjected to what is known as
"the naphthol prepare" a colour or colours or colouring substance or substances
of the paranitraniline series of nitrosamine red along with black, blue, green and
yellow or one or more of thein.
Dated this Twenty-second day of November 1895.
