The jacquard weave is a raised design woven into a fabric, achieved through an arrangement fitted on a loom, meant to create fine, exquisite patterns within the weaving process on the fabric. Jacquard weaving makes it possible on any sort of loom, the programmed raising of each warp thread independent of the others.This has brought about greater versatility to the weaving process and offers the highest level of warp yarn control.
The jacquard weave is a raised design woven into a fabric, achieved through an arrangement fitted on a loom, meant to create fine, exquisite patterns within the weaving process on the fabric. The jacquard attachment between the warp threads provides for flexibility during the weaving of the fabric and allows patterns to be created in extraordinary shapes in fine detail.Named after their inventor, Joseph Marie Jacquard, the Jacquard process and the necessary loom attachment are probably one of the most important weaving inventions made.
as Jacquard shedding has made possible the automatic production of unlimited varieties of pattern weaving.In former times if figured designs were required, this was done on a draw loom. The heddles with warp ends to be pulled up were manually selected by a second operator (draw boy), apart from the weaver. It was slow and labour intensive, with practical limitations on the complexity of the pattern.The first important improvement was when Basile Bouchon introduced the principle of applying a perforated band of paper.
A continuous roll of paper was punched by hand, in sections, each of which represented one lash or thread, and the length of the roll was determined by the number of shots in each repeat of pattern.Joseph Marie Jacquard recognized that although weaving was intricate, it was repetitive, and saw that a mechanism could be developed for the production of sophisticated patterns just as it had been done for the production of simple patterns. The Jacquard machine subsequently evolved from this.
