Improvements in the Manufacture and Ornamentation of Plain and
other Woven Fabrics.
I JOHN PEARSON of Callis Mill, Charlestown, near Hebden Bridge, in the
County of York, Cotton 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 following statement that is to say :-
My said invention relates to improved means for obtaining ornamental
effects in plain and other woven fabrics, such effects being obtained by prosenting
the fibre of the material composing the fabric at different angles to the light,
whereby I obtain delicate tones and contrast not attainable by the use of coloured
or shaded material.
Thie method of producing ornamentation in woven fabrics was discovered and
provisionally protected by me on the 27th October 1892, No. 19274 but only as
regards corded goods. Further experiments and discovery have proved to me
that the invention can also be applied to the production and ornamentation of
other woven goods for example, plain woven fabrics such as satin drills warp
faced fabrics, twills and even calicoes, and also to the ornamentation of cut pile
goods.
In carrying my invention into effect I employ mixtures of yarn spun right and
left, the consequence being that whon woven into a fabric the portions with
which the right hand spun yarns are incorporated, present a shade or appearance
different from the portions into which the left hand spun yarns are woven and
thus by contrast an ornamental offect is obtained the appearance of which can be
varied to any extent by weaving geometrical patterns or stripes into the cloth.
The method of weaving fabrics according to my invention may be infinitely varied.
For example in the production of goods intended to have shade stripes, the warp
may be composed of alternate sections of right and left spun yarus and the weft
be of the ordinary description, the resulting fabric presenting the required shade
stripes throughout its length. I might however produce the same effect by using
right and left hand spun weft in a two shuttle loon, throwing the right and left
spun weft alternately to the face and back of the fabric, in combination with
either a mixed or uniform warp.
In the same manner patterns may be woven into the cloth by judicious
combinations of the right and left spun yarns either in the warp or in the weft or
in both.
In some cases coloured yarns might be introduced to heighten the variety or
increase the effective appearance of the goods. The effects which can be obtained
under my invention by presenting the fabrics at different angles to the light,
constitute new and graceful departures from the ordinary methods of ornamenting
woven fabrics. The effects obtained in fabrics woven in accordance with my
invention are not less apparent after the fabric has been dyed or bleached but
are on the contrary improved by the dyeing or bleaching operation.
Having now particularly described and ascertained the nature of my said
invention and in what mannor the same is to be performed I declare that what
I claim is :-
In the weaving of plain goods and goods other than corded fabrics the
employment of right and left spun yarus in the warp, or in the weft, or in both,

page_text: the said yarns being so woven into the goods as to produce ornamental effects in
the manner and substantially as hereinbefore described.
