THOMAS TEMPEST-RADFORD of Kidderminster in the County of Worcester,
Carpet Manufacturer IMPROVEMENTS IN THE MANUFACTURE OF CARPETS AND
OTHER FABRICS
Heretofore in the manufacture of carpets and other fabrics the pattern thereof has
sometimes been produced by the use of printed warp wound, on a beam and woven
in a plain loom but in fabrics produced by such method of manufacture, although
a large number of colors can be introduced, there is wanting the sharpness of
outline and brilliancy of effect which are obtained in fabrics produced by the use
of the Jacquard loom in combination with frames of dyed warp whilst when
weaving carpets and other fabrics by the latter method it has been found
impracticable, on account of expense to introduce such a variety of colors in the
pattern as are obtainable by the use of printed warp.
Now according to my Invention I am enabled to produce carpets and other
fabrics with all the richness of coloring now obtained by the use of printed warp,
together with the sharpness of outline, brilliancy of effect and durability in wear
of carpets and other fabrics woven in a Jacquard loom.
In carrying my Invention into effect I employ a printed warp in combination
with one, two or more frames of dyed or other warp. These I arrange in a
Jacquard loom in such manner that the printed warp shall produce the general
body of the pattern and the frame or frames of dyed or other warp the outline,
ground color and if desired some other portions of the pattern or any one or more
of such parts.
The printed warp according to one method of working, is not as heretofore
wound on a beam from which the warp is drawn off at uniform speed but each
thread thereof is wound upon a separate bobbin or reel and suitable means are
provided so that each thread of such printed warp shall be capable of being drawn
off its bobbin or reel in proportion as it is used and independently of the others of
such threads.
In printing the warp for weaving in the manner above described I print the
various widths of color thereon in the required order to produce the general body
n

where it will lie embedded in the body of the fabric under the frame warps when
the latter are raised to produce the outline, ground color or other parts of the
design.
on &
In some cases however instead of winding each thread of the printed warp
separate bobbin or reel I wind the entire printed warp on a beam so as to give off
an equal length of each thread thereof in the weaving of the fabric but in this
case the printed warp instead of lying embedded in the body of the fabric at
certain parts under the frame warps is raised over every wire or shoot of weft
employed in lieu of a wire and the frame warps are also at such parts raised above
the said wires or shoots of weft and above the printed warp so as to cover the
latter. This method of working is not however so advantageous as the foregoing
as wherever the printed warp and the frame, warp are both raised above the wire or
shoot of weft employed in lieu thereof there will be a greater quantity of warp
than at the other parts thereby producing an unevenness in the fabric.
If however in producing the design care be taken to give each thread of printed
warp the same length of blank or unprinted space the said printed warp, although
wound on a beam can be sunk in the body of the fabric at those parts where the
frame warps are employed to produce the outline, ground color or other parts of
the pattern.
My Invention is applicable to the manufacture of terry, cut pile, and other
descriptions of carpets and other fabrics.
