IMPROVEMENTS IN THE METHOD OF OBTAINING TURKEY RED AND OTHER COLOURED YARNS
Year: 1878

page_text: LETTERS PATENT to James Hodgkinson, of Southport, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN THE METHOD OF OBTAINING
TURKEY RED AND OTHER COLOURED YARNS."
PROVISIONAL SPECIFICATION, left by the said James Hodgkinson at the
Office of the Commissioners of Patents on the 25th May 1878.
JAMES HODGKINSON, of Southport, in the County of Lancaster. "IMPROVEMENTS
IN THE METHOD OF OBTAINING TURKEY RED AND OTHER COLOURED YARNS."
My Invention relates principally to the production of Turkey red yarns from
cotton; but is also applicable in the production of cotton yarn of other colours,
such, for example, as indigo blue yarn, and also in the production of coloured yarns
from flax, jute, wool, and other fibrous substances. In the ordinary processes the
Turkey red colour is obtained by subjecting either the yarn or cloth woven there-
from to dyeing processes.
According to my Invention I take the uncarded cotton, or I take the material
when in the condition of a sliver or roving after being carded but before being spun
into yarn, and I subject the said cotton or the material when in the indicated
condition to the dyeing processes. The said processes may be similar to those
employed in the treatment of woven fabrics or yarns when dyeing Turkey red with
the exception that the cotton is dried and opened between the several processes or
liquorings." The opening may be effected by any suitable means, but I prefer to
employ a Crighton opener " for the purpose. I do not confine myself to this
opening if a sufficiently good effect can be obtained without it.
<<
k
The dyed cotton or material is subsequently spun into yarn either alone or
combined with undyed cotton slivers or rovings, or with cotton slivers or rovings of
a different colour or shade.
By combining undyed cotton slivers or rovings with the dyed cotton slivers or

page_text: rovings I am enabled to obtain any required shade of colour, and to obtain shades
of colour which could not conveniently directly be; obtained in the ordinary dyeing
processes; and I am also enabled to obtain coloured yarns of higher counts, that is
to say, I obtain finer yarns than can now be directly dyed to practical advantage.
When producing indigo blue yarn, or yarn of colours other than Turkey red, I
subject the slivers or rovings to the treatment suitable to obtain the desired colour,
and I subsequently spin the slivers or rovings into yarn, either aloue or combined
with other slivers or rovinga undyed or dyed a different colour or shade.
It may be considered to be advisable in some cases to recard the dyed slivers or
rovings before subjecting them to the spinning processes, as, for example, before ]
subjecting them to the action of the drawing frames.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said James Hodgkinson in the Great Seal Patent Office on the 23rd
November 1878.

In my Provisional Specification I mentioned that my Invention was applicable
to the dyeing of indigo blue and other colours than Turkey red, but I have not
included such application herein, and I make no claim in respect thereof; and I
disclaim the extension of my Invention to the dyeing of other colours than Turkey
red; and I would have it to be understood that I claim the production of Turkey
red yarn by subjecting the uncarded cotton or other fibrous material, or the slivers
or rovings of carded cotton or other fibrous material to the Turkey red dyeing
processes previously to the subjection of such cotton slivers or rovings or of the
fibrous material to the spinning processes.
In witness whereof, I, the said James Hodgkinson, have hereunto set my hand
and seal, this Twenty-second day of November, in the year of our Lord
One thousand eight hundred and seventy-eight.
