COMPLETE SPECIFICATION.
An Improved Means or Method of Dyeing and Bleaching Warp
upon a Warp Beam.
I, GEORGE KEIGHLEY, of Bankhouse Iron Works, Burnley, in the County of
Lancaster, Machine 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 has reference to prior Letters Patent granted to me on the
13th day of March A.D. 1894 No. 5186.
The invention described in the Specification of the above named Letters Patent
consisted in the use of a perforated hollow beam upon which the warp was wound,
and means were employed for forcing hot water and afterwards dyeing liquor
through the warp from the outside and through the perforated hollow beam upon
which the warp was wound, but in practice I have found that the dyeing liquor
was not equally distributed amongst the warp threads but that the said liquor
passed through the warp in streams, whereby the warp was unequally dyed. To
avoid this, is the object of my present invention and this accomplish by placing
one or more layers of calico or other permeable material between the perforated
beam and the warp or in any part thereof for the purpose of arresting or retarding
the progress of the dyeing liquor, by which means the dye liquor is distributed and
acts slowly and gradually and equally throughout the body of the warp, permeating
every part of it and dyeing it an equal shade throughout.
The dye liquor may enter within the perforated tube, in which case, the
permeable material is wrapped around the outer periphery of the warp or near to
it; but if the dye liquor is made to pass through the warp from the outside, then in
that case, the intermediate or permeable material must be wrapped around the
perforated tube or near to it.
I do not however limit myself to the exact position of the intermediate substance
nor to the material used, as the intermediate part for arresting or retarding the
advance of the die liquor may consist of other materials such as flannel, paper,
wire gauze or cther fibrous or permeable substance or material for effecting the
same purpose, the primary object of my invention being to allow the liquor to
percolate slowly through the whole warp substance before it passes through the
perforated beam or vice versa.
Previous to dyeing the warp it is preferably got into a proper condition for
taking the dye, by subjecting it to the action of hot water in the same manner as
the dyeing process.
When bleaching warp the process is the same as that described for dyeing, but
the liquor is changed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
The application to or in combination with a perforated warp beam of a
permeable material or substance employed in the manner and for purposes herein
set forth.
Dated this 8th day of March 1895.
