Jacquard-Woven Tapestries
Three different stages are involved in the
weaving process. As the first stage, a designer creates the artwork
for the new tapestry from an original doccument or museum illustration.
Once the finished artwork is approved, it is interpreted into
a techinical design called a 'mise en carte'. From this technical
artwork a 'Jacquard' is produced. This is a series of perforated
cards, a system invented in 1804 by Joseph Jacquard (1752-1834)
enabling intricate designs to be woven.
Then the weaving loom is set up. This process
is known as 'warping' and is a lengthy and delicate operation,
involving the attachment of approximately 12,000 horizontal warp
threads to the corresponding number of vertical loom-heddles.
When the Jacquard card has been placed on the loom from side
to side. Each of the perforations on the Jacquard card will activate
the movement of the warp threads, allowing the weft yarns in
the shuttles to pass correctly between the warps, thereby creating
the design. Once an acceptable trial result has been achieved,
the weaving process can begin. The weaving process requires much
skill and attention to detail. A weaver has various tasks to
fulfil in overseeing the operation of a loom. His skills include
placing the correct weft spools in the shuttles and renewing
them when necessary, and controlling the weaving tensions. The
weft yarns are carefully selected from a vast range of different
shades, in order to achieve the desired tones in the tapestry. |
