I, LIONEL CICERO GAUNT SHARP, of the Tower Dye Works, Low Moor,
near Bradford, in the County of York, Dyer, Printer and Colour Maker, do
hereby declare the nature of this invention to be as follows:
זי
This invention relates to the production of coloured border effects in combination
with fast dyed black grounds upon ordinary grey cotton cloths especially suitable
for umbrella cloths and selvedges.
The invention consists in producing upon an ordinary grey cotton cloth,
combination of fast dyes unalterable in rain or sun with coloured or illuminated
borders and fast black or brown grounds. Hitherto such effects have only been
produced by the more costly mode of weaving in the cloth coloured yarns to
produce the required effects.
In carrying my invention into effect, I treat the materials to a process of dyeing
which leaves the cloths almost colourless, the goods are next desiccated under
anitable conditions, and in this condition the cloth is capable of being developed
into fast black, but in order to produce border effects of various colours, the
desiccated colourless cloth has the coloured bordered effects printed and dried upon
the cloth. The colour used for border printing should contain re-agents capable
of preventing the colourless dye materials with which the cloth was first impregnated
from developing, when such dyes first put upon the body of the cloth are developed
into fast black, at the same time the colours printed to form the border effects are
fixed upon the fibre.

Improvements in the Production of Coloured Border Effects on
Fast Black Dyed Grounds upon Ordinary Grey Cotton Cloths,
especially suitable for Umbrella Cloths, Selvedges, and the like.
1, LIONEL CICERO GAUNT SHARP of the Tower Dye Works, Low Moor,
near Bradford in the County of York, Dyer, Printer and Colour Maker, 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:-
This invention relates to the production of coloured border effects in combination
with fast dyed black grounds upon ordinary grey cotton cloth, especially suitable
for umbrella cloths and selvedges.
The invention consists in producing upon an ordinary grey cotton cloth, a
combination of fast dyes unalterable in rain or sun with coloured or illuminatel

page_text: borders and fast black or brown grounds. Hitherto such effects bave only been
produced by the more costly mode of weaving in the cloth ccloured yarns to
produce the required effects.
In carrying my invention into effect, I treat the materials to a process of dyeing
which leaves the cloths almost colourless, the goods are next desicoated under
suitable conditions, and in this condition the cloth is capable of being developed
into fast black, but in order to produce border effects of various colours, the
desiccated colourless cloth has the coloured bordered effects printed and dried upon
the cloth. The colour used for border printing should contain re-agents capable
of preventing the colourless dye materials with which the cloth was first impregnated
from developing when such dyes first put upon the body of the cloth are developed
into fast black, at the same time the colours printed to form the border effects are
fixed upon the fibre.
.
The following are the suitable materials and proportions thereof which I prefer
to use in the aforesaid dyeing and printing operations, but I do not limit myself to
such, as they are given only as an example to illustrate the carrying out of the
invention:
For impregnating the cloth, there may be used for example a mixture of 50 lbs.
of aniline hydrochloride, 10 lbs. of ferrocyanide of potassium and 20 lbs. of chlorate
of potash in about 50 gallons of water.
The discharge or resist to be used with the colour for printing upon the ground
may be caustic soda thickened with starch paste.
The oxidising to develop the black or brown leaving the printed parts white or
coloured, is preferably effected in a room at 160 degrees (Fahrenheit) on a dry
bulb thermometer and 140 degrees on a wet bulb.

:
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 improved method of producing coloured border effects on ordinary grey
cotton cloths, especially suitable for umbrella cloths, selvedges and the like, which
consists in dyeing the cloth with materials which leave it almost colourless when
impregnated, in then desiccating and rendering the cloth capable of being developed
into a fast black or brown ground, then printing and drying upon the cloth,
coloured border effects in colours containing re-agents capable of preventing the
colourless dye materials with which the cloth was first impregnated from developing
at the parts so printed upon, and finally developing the fast black or brown ground,
substantially as described.
