 Weaving is an ancient textile art and craft that involves placing two sets of threads or yarn made of fiber called the warp and weft of the loom and turning them into cloth. This cloth can be plain (in one color or a simple pattern), or it can be woven in decorative or artistic designs, including tapestries.
The majority of commercial fabrics, in the West, are woven on computer-controlled Jacquard looms. In the past, simpler fabrics were woven on other dobby looms and the Jacquard harness adaptation was reserved for more complex patterns. Some believe the efficiency of the Jacquard loom, and the Jacquard weaving process makes it more economical for mills to use them to weave all of their fabrics, regardless of the complexity of the design. However, an industrialist weaving large runs of simple plain weave fabric may need to be convinced of the logic of investing in Jacquard machines, when a much lower cost loom would suffice.
Handweaving, along with hand spinning, is a popular craft. Weavers use wooden looms to create rugs, fabrics, and tapestries.
Fabric in which the warp and/or weft is tie-dyed before weaving is called ikat. Fabric decorated using a wax resist method is called batik.
Satin weaves, twill weaves, and plain weaves are the 3 basic types of weaving by which the majority of woven products are formed.
PROCESS
In general, weaving involves the interlacing of two sets of threads at right angles to each other: the warp and the weft. The warp are held taut and in parallel order by means of a loom. The loom is warped (or dressed) with the warp threads passing through heddles on two or more harnesses. The warp threads are moved up or down by the harnesses creating a space called the shed. The weft thread is wound onto spools called bobbins. The bobbins are placed in a shuttle which carries the weft thread through the shed. The raising/lowering sequence of warp threads gives rise to many possible weave structures from the simplest plain weave (also called tabby), through twills and satins to complex computer-generated interlacings.
Both warp and weft can be visible in the final product. By spacing the warp more closely, it can completely cover the weft that binds it, giving a warpfaced textile such as rep weave. Conversely, if the warp is spread out, the weft can slide down and completely cover the warp, giving a weftfaced textile, such as a tapestry or a Kilim rug. There are a variety of loom styles for hand weaving and tapestry. In tapestry, the image is created by placing weft only in certain warp areas, rather than across the entire warp width.
