PROVISIONAL SPECIFICATION.
Improvements in the Production of Certain Figured Woven Fabrics.
I, GEORGE DOUGLAS, of the Firm of Edward Ripley & Son, Bowling Dye Works,
Bradford, in the County of York, Dyers, do hereby declare the nature of this
invention to be as follows:-
"
The class of figured fabrics to which this invention particularly relates is woven
from a combination of animal and vegetable yarns, and a raised figure, pattern
or design is then produced by mercerizing" the fabric to contract the vegetable
yarn and cause the animal yarn appearing upon the face in the form of a pattern or
design to stand out in relief by reason of its greater length. The object of this
invention is to reduce the cost of production.
To carry out my invention I wind the two yarns together, preferably with little
or no twist, on to weft bobbins, or their equivalent, and weave them into the fabric
side by side in the form of weft. I afterwards mercerize the fabric.
In this way single fold yarn of animal fibre along with cotton yarn may be
introduced as weft in plain looms; and in addition to the reduced cost, in the case
of lustre yarns such as mohair a better effect is obtained for the yarn does not
require the same amount of twist as when it is introduced in the warp owing to the
tensile strain being less.

COMPLETE SPECIFICATION.
Improvements in the Production of Certain Figured Woven Fabrics.
I, GEORGE DOUGLAS, of the Firm of Edward Ripley & Son, Bowling Dye Works,
Bradford, in the County of York, Dyers, 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 class of figured fabrics to which this invention relates is woven from a com-
bination of animal and vegetable yarns, and a raised figure, pattern or design is
then produced by "mercerizing" the fabric to contract the vegetable yarn and
cause the animal yarn appearing upon the face in the form of a pattern or design to
stand out in relief by reason of its greater length. The object of this invention
is to reduce the cost of production.
To carry out my invention I wind the two yarns together, preferably with little
or no combined twist, on weft bobbins, or their equivalent, and so weave them

page_text: into the fabric side by side in the form of weft. The fabric is afterwards
mercerized as usual.
In this way single fold yarn of animal fibre may be together introduced along
with cotton yarn as weft in plain looms (that is to say: looms in which the samo
shuttle is continuously reciprocated), and in addition to the reduced cost, a better
effect is obtained particularly in the case of lustre yarns such as mohair for the
yarn is to some extent supported by the stronger cotton thread whilst it is intro-
duced and consequently does not require the same amount of twist as when it is
introduced either by itself as weft or in the warp owing to the tensile strain being
Iess.
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:-
:-
1. The improved method of weaving this class of figured fabric, namely: by
introducing the yarn of animal fibre in the form of weft at the same time as the
cotton weft and from the same bobbin or its equivalent, substantially as herein
described.
2. The improved method of weaving this class of figured fabric, namely: by
introducing the yarn of animal fibre as weft simultaneously with the cotton weft
and by the same shuttle, substantially as herein described.
