Weaving

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 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. The efficiency of the Jacquard loom makes it more economical for mills to use them to weave all of their fabrics, regardless of the complexity of the design.

Hand weaving, 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.

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's many threads are held taut and in parallel order by means of a loom. The loom is dressed, or set up, with the warp threads. The weft threads can be wound onto shuttles. The weft thread crosses the warp in some over/under sequence. The nature of that sequence gives rise to many possible patterns and structures from the simplest plain weave, through twills and satins to complex computer-generated interlacing.

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 warp-faced textile. Conversely, if the warp is spread out, the weft can slide down and completely cover the warp, giving a weft faced 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 only placing weft in certain areas, rather than in the weave structure itself.
