Improvements in the Manufacture of Mixed or Multi-coloured Yarns
and Fabrics.
I, FELIX MEYER, of 78, Williamstreet, Aix-la-Chapelle, Rhenish Prussia,
Germany, Manufacturer, do hereby declare the rature of this invention to be as
follows:-
The object of my present invention is a new and most simplified way for
fabricating mixtures in botany, cheviot and other woollen yarns, as well as
multicoloured twists and cloths which contain such yarns.
While up to now mixtures were made by mixing woollen fibres of different
shades each of which had to be dyed, and while multi-coloured twists were fabri-
cated by twisting threads of different shades which had also to be dyed first, the
new and simplified way of making those yarns and cloths which contain such
yarns, is as follows:
Woollen fibre, either wool, or tops, or noils, or any other kind of woollen material
is prepared or mordanted for example by fixing chromic acid on the fibre.
Now the prepared woollen fibre is mixed with unprepared fibre or with fibre
prepared in an other way and then they are spun together.
For multicoloured twists the prepared or mordanted thread is twisted with
unprepared thread or with threads prepared in an other way.
It is advisable to give the prepared or mordanted wool or thread a light red
or blue shade, in order to have a better control over the mixing or twisting process.
The yarn, fabricated in the above described way, is either dyed in the yarn,
in hanks or skeins, or it is woven and then dyed in the piece. In either case the
yarn or cloth is dyed thus, that the prepared fibre gets a shade different from that
of the unprepared fibre as well as from that of the fibre prepared in an other
way.
So an effect of two or more shades, according to the number of kinds of prepared
fibres and unprepared fibres, is made by dying the aforesaid mixtures or twists
in hanks or in the piece.
The dying is done with a combination of colouring stuffs which either have no
effect on unprepared fibres, or have a different effect on prepared fibres and on unpre-
pared ones, or which dye both classes of fibres in the same way.

I. FELIX MEYER, of 78, William Street, Aix-la-Chapelle, Germany, Manufacturer,
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 follow-
ing statement:-
The object of my present invention is a new and simplified way for fabricating
mixtures in botany, cheviot, and other woollen yarns, as well as multicoloured
twists and cloths which contain such yarns.
While up to now mixtures were made by mixing woollen fibres of different
shades each of which had to be dyed and while multicoloured twists were fabri-
cated by twisting threads of different shades which had also to be dyed first tha
new and simplified way of making those yarns and cloths which contain such
yarns, is as follows:-
Woollen fibre, either wool, or tops, or noils, or any other kind of woollen material
is prepared or mordanted for example by fixing chromic acid on the fibre.
The prepared woollen fibre is then mixed with unprepared fibre or with fibre
prepared in another way for example by the use of a different mordant, and then
they are spun together.
For multicolored twists the prepared or mordanted thread is twisted with
unprepared thread or with threads prepared in another way.
It is advisable to give the prepared or mordanted wool or thread a light red
or blue shade, in order to have a better control over the mixing or twisting process.
The yarn, fabricated in the above described way, is either dved in the yarn,
in hanks or skeins, or it is woven and then dyed in the piece. In either case the
yarn or cloth is dyed thus, that the prepared fibre gets a shade different from that
of the unprepared fibre as well as from that of the fibre prepared in another
way.
So an effect of two or more shades, according to the number of kinds of prepared
fibres and unprepared fibres, is made by dyeing the aforesaid mixtures or twists
in hanks or in the piece.
The dyeing may be done with a combination of colouring stuffs one at least
of which must either have no effect on unprepared fibres, or have a different effect
on prepared fibres and on unprepared ones, whilst the other or others may dye
both classes of fibres in the same way.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I wish it to be under-
stood that I am aware that fabrics have before been made by, weaving together
prepared and unprepared yarns and then dyeing and that I make no claim to
this but I declare that what I claim is:-
-
1. The manufacture of mixed or multicoloured yarns and fabrics by mixing
prepared woollen fibres with unprepared woollen fibres, by afterwards spinning
the thus mixed fibres and by either dyeing the spun yarn or by weaving it to
fabrics and then dyeing those fabrics.

page_text: 2. The manufacture of multicoloured yarns and fabrics by twisting prepared
woollen threads with unprepared woollen threads, by either dyeing the twisted
yarn or by weaving it to fabrics and then dyeing those fabrics.
