for example cotton from cotton seed pods, linen from flax stems, wool from sheep hair, or silk from the spun cocoons of silkworms. In addition to these traditional materials, synthetic materials such as plastic acrylic are now used.
In order for the fiber to be made into cloth or clothing, it must be spun (or twisted) into a strand known as yarn. When the yarn is ready and dyed for use it can be made into cloth in a number of ways. Knitting and crochet are common methods of twisting and shaping the yarn into garmets or fabric. The most common use of yarn to make cloth is weaving. In weaving, the yarn is wrapped on a frame called a loom and pulled taut vertically. This is known as the warp. Then another strand of yarn is worked back and forth wrapping over and under the warp. This wrapped yarn is called the weft. Most art and commercial textiles are made by this process.
