for the Production of an Evenly Mixed Dyed Yarn.
1, JOAH LODGE, of Bath Mills, Lockwood, near Huddersfield, Yorkshire Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
The special object of my invention is the production of even mixed dyed yarns of
various shades of colour blended together, so that when woven into a cloth, the
cloudiness hitherto found on woven mixed fabrics will be obviated.
Hitherto the mixed coloured yarns have been produced by dyeing the whole of the
tops or slivers, and blending them with tops or slivers of other colours or undyed, but
in consequence of the variation in the length of the staple, some fibre being much
longer in the staple than others, the blending of the colours has produced uneven
and cloudy yarn, consequently, when woven into a fabric, the unequal shade of the
yarn has made the cloth cloudy or streaky. To prevent cloudiness in woven fabrics
is the primary object of my invention, and this I propose to accomplish by a new
treatment of the top or sliver.
To carry out my invention I dye the top or sliver in such a manner that parts
of the tops are dyed one colour, and the remaining parts are left undyed in the
grey or ground colour, that is to say, I dye the top in which 1 choose to term
blocks and spaces; for instance, I block the part to be left undyed, and the space
left between the blocked part, is left for dyeing; or in other words one part of the
sliver is covered and not exposed to the dye liquor, whilst the remaining part of
the sliver is uncovered and therefore exposed to the liquor. After the top has
been thus dyed it is taken and combed or otherwise similarly treated, by which
means the blending of the dyed or undyed fibre will be equalized, producing yarn
of even shade throughout, consequently, when woven into a cloth, the cloudiness
hitherto complained of will be absent.
The means or method of producing the intermittently dyed top or sliver may be
various; therefore wish to make no claim to any form of mechanism for dyeing
tops or sliver in spaces.

page_text: for the Production of an Evenly Mixed Dyed Yarn.
I, JOAN LODGE, of Bath Mills, Lockwood. near Huddersfield, Yorkshire, Manu-
facturer, 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:-
The special object of my invention is the production of evenly mixed dyed yarns of
various shades of colour blended together, so that when woven into a cloth, the
cloudiness hitherto found on woven mixed fabrics will be obviated.
Hitherto mixed coloured yarns (meaning thereby yarns formed of differently
coloured fibres mixed together) have been produced by dyeing the whole of the tops
or slivers used in forming the yarn, and blending them with tops or slivers of other
wholly dyed colours, or wholly undyed. It has proved that in consequence of the
variation in the length of the staple of the wholly dyed fibres, some fibre being much
longer in the staple than others, the blending of the colour has produced uneven and
cloudy yarn, consequently, when woven into a fabric, the unequal shade of the yarn
has made the cloth cloudy or streaky-To prevent cloudiness in woven fabrics is the
primary object of my invention, and this I propose to accomplish by a new treatment
of the top or sliver, which will enable yarns to be formed in which suitable partly
dyed fibres are evenly mixed and blended, and the injurious effects, due, as I have
ascertained, to the practice, hitherto adopted, of mixing wholly dyed fibres, may be
advantageously obviated.
yarns
In some cases tops or slivers have been prepared by printing colours upon them.
but when such tops or slivers are subsequently treated and formed into
which are
woven into fabrics, the result has been that the surfaces are soon spoiled, as the
printed colours are fugitive and fade away. To the preparation or use of such printed
tops or slivers, or to yarns formed from them, I make no claim.
To carry out my invention, I prepare the tops or slivers intended to be used in
forming the yarns by first dyeing them in such a manner that parts of the tops are
dyed one colour, and the remaining parts are left undyed, in the grey or ground
colour that is to say, I dye the top in what I term blocks and spaces; for instance,
I block the part to be left undyed, while the space left between the blocked part
is allowed to take the dye; or in other words, one part of the sliver is covered and
not exposed to the dye liquor, whilst the remaining part of the sliver is uncovered,
and therefore exposed to the action of the dye liquor, the result being that a striped
appearance is given to the tops or slivers. In some cases, instead of treating undyed
tops or slivers in the manner above described, wholly dyed tops or slivers having
a self colour may be partly blocked and dyed so as to produce fibres that are
suitable for my purpose. After the tops have been thus dyed they are combed in
the usual way or otherwise similarly treated, by which means the partly dyed fibres
.

undyed fibre will be equalized, producing yarn of even shade throughout. The
result will be that yarn manufactured by my improved process will, when woven
into a cloth, produce a fabric which will not present the defective appearance of
cloudiness hitherto the subject of frequent complaint and difficulty.
There are several obvious methods of producing the space-dyed tops or slivers, so
as to enable fibres to be produced, that may be used in my improved process, and
persons experienced in dyeing would have no difficulty in employing some one
or more of them. But I have found that the special apparatus for which I applied
for Letters Patent on November 4, 1887 No. 15022 may be used with great advantage
as regards economy and efficiency. That apparatus is fully described in the complete
specification of my said letters patent.
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
I claim is
Firstly. The manufacture of improved mixture yarns by combining worsted tops
and other slivers, the fibres of which are dyed in spaces and afterwards formed
into yarns, substantially as described.
Secondly. The improved process of preparing tops or slivers, by dyeing the several
tops or slivers in parts, so that when mixed they may form evenly blended mixture
yarns, suitable for being woven into cloth, in which the tendency to a streaky
or cloudy appearance is obviated.
