A NEW COLOUR STARCH
Year: 1884

page_text: I, EMIL CAPITAINE, of 89 Chancery Lane, in the County of Middlesex, Engineer,
do hereby declare the nature of the said invention for "A NEW COLOUR STARCH"
to be as follows:-
The invention consists in amalgamating with starch in the course of its manu-
facture any suitable brown or yellow colouring matter, or compounds or mixtures
of the said two colouring matters in order that by making a watery solution of
this colour starch, and steeping woven fabrics, spun threads, fibres, et cotera,
therein, a cream colour shall be communicated to the same, simultaneously with
the starching operation. Hitherto it has been the practice to add the colouring
matter to the starch only after a watery solution of the starch has been made.
Therefore the invention essentially cousists in adding the colouring matter during
the process of manufacturing the starch and thus providing a new commercial
product which possesses in itself the requisite quantity of that particular colouring
matter that is necessary to communicate a cream colour of the desired shade. As
the cream colour may be required to be of varying shades from light to dark, s0
also the colouring matter and the proportions of the same may vary relatively to
the quantity of starch. Thus, the precise quantity of yellow or brown colouring
matter to be mixed with a given quantity-say one pound of the starch
cannot be stated. The quantity of colouring matter employed varies considerably
according as it may be desired to produce a light or dark cream colour. Again,
colouring matters are of different strength or intensity so that a different proportion
of the ingredients is employed for nearly every different colouring matter.
before explained the addition of the colouring matter is effected in the process of
the manufacture of the starch. The method of mixing may of course vary very
much. No new machine or new process is employed by me for the purpose of
carrying out the mixing operation which is purely mechanical and may be done by
band labour or by means of known stirring incchanism. Any of the known yellow
and brown colouring matters may be employed for the purpose of this invention"
such as the yellow colouring matters known under the name of:-Saffron, baryum,
calcium, annatto, turmeric, picric acid, chromate of lead or iron, fustic, xanthino,
[Price 4d 1
As

page_text: fustet, weld, quercitron, rhamnin or combinations of these, and the brown
known under the name of:-Cutch, aloc, camwood copperas or combinations
thereof.
This colour starch may also be made with an addition of so much of the
colouring matter as to require the addition to the same before using of a given and
corresponding quantity of ordinary white starch for the purpose of producing lighter
shades.
I, EMIL CAPITAINE of 89 Chancery Lane, in the County of Middlesex, Engineer
and Patent Agent, do hereby declare the nature of the said invention for "A NEW
COLOUR STARCH a communication to me from abroad by Drumm and Co of
Kaiserlautern, Germany, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The invention consists in amalgamating with starch in the course of its manu-
facture any suitable brown or yellow colouring matter or compounds or mixtures
of the said two colouring matters, in order that, by making a watery solution of
such colour starch and steeping woven fabrics, spun threads, fibres etcetera
therein, a cream colour shall be communicated to the same simultaneously with
the starching operation. Hitherto it has been the practice to add the colouring
matter to starch only after a watery solution of the starch has been made,
therefore the invention essentially consists in adding the colouring matter during
the process of manufacturing the starch and thus providing a new commercial
product which possesses in itself the requisite quantity of that particular colouring
matter that is necessary to communicate a cream colour of the desired shade.
the cream colour may be required to be of varying shades from light to dark so
also the colouring matter and the proportions of the same relatively to the
quantity of starch may vary. Thus the precise quantity of yellow or brown
colouring matter to be mixed with a given quantity-say one pound of the
starch, cannot be stated.
As
The quantity of colouring matter employed varies considerably according as it
may be desired to produce a light or dark croam colour. Again, colouring
matters are of different strength or intensity so that a different proportion of
the ingredients is employed for nearly every different colouring matter. As
before explained the addition of the colouring matter is effected in the process of
manufacture of the starch. The method of mixing may of course vary very
much. No new machine or new process is employed by me for the purpose of
carrying out the mixing operation, which is purely mechanical and may be done by
hand or by means of known stirring mechanism. Any of the known yellow
and brown colouring matters may be employed for the purpose of this invention,
if they are suitable therofor.

page_text: The colouring matter may also be added in a quantity sufficiently large to
render it necessary to add to this starch before use a corresponding quantity of
ordinary white starch in order to obtain lighter shades of colour.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is,
The production of colour starch by the addition-in and during the process of
the manufacture of starch-of a yellow or brown colouring matter, or compounds
or mixtures of such two colouring matters to the same for the purpose of producing
a colour starch ready for use which on being dissolved in water gives a solution
that simultaneously with the starching operation communicates a cream colour to
the woven fabrics, spun threads, fibres, et cetera, steeped therein, substantially as
hereinabove described.
