According to the BBC, woven fabrics are made by weaving together yarn strands in an over-under pattern. Warp threads are strung vertically on a loom, and then a weft thread is woven horizontally through the warp. When the weft thread reaches the end, it can be looped over and passed back the other way, forming an S-shaped curve as it progresses up the loom.
Woven fabrics are easy to cut, and many different patterns can be produced on the fabric surface. There are several different methods used in weaving. The simple over-under pattern of a plain weave creates the strongest fabrics, but more delicate weaves, like the satin weave drape, create a more delicate fabric and are often used in clothing. The twill weave is a diagonally-patterned weave that combines strength and flexibility. Its best-known use is in making denim blue jeans.
Woven fabrics are made on a loom, which is a square structure designed to hold the warp threads in place while the weft thread is woven through. Hand looms made of wood have been in use by cultures around the world for thousands of years. However, industrial looms that are used in large fabric manufacturing plants are usually made of metal because of the heavy physical demands on the loom.
