Jacquard is a patterned fabric produced on a weaving loom. May be sectional or all-over design in color and texture.
The jacquard head motion is the most complex shedding system. It is named after its inventor Joseph Marie Jacquard who developed the system in 1801 to be used on hand looms. The jacquard has advanced significantly since then but it still works on the same principle today.
Jacquard shedding exhibits control on each individual warp yarn independent of all other warp yarns. Up to 12,000 warp ends can be controlled. These systems can employ mechanical or electronic devices to actuate the warp ends. Design capability is virtually unlimited. Pattern areas can equal the width of the fabric and are almost unlimited in the length. Fabrics made on jacquard looms are normally more expensive because of their complexity and slower weaving speed. There are no harness frames on this style of loom. Each end is activated independently, being controlled by its own harness cord from the jacquard head. The harness cord is attached to a heddle which is pulled down by a spring in most cases, but in some of the older and slower models, weights are used to pull the heddles down to achieve the pattern.
