Rayon
Rayon
Rayon (/ˈreɪ.ɒn/) is a synthetic fiber, made from natural sources such as wood and agricultural products that are regenerated as cellulose fiber. The many types and grades of rayon can imitate the feel and texture of natural fibers such as silk, wool, cotton, and linen.
Etymology
The term rayon was officially adopted by the textile industry in the year 1924. The word is derived from the French word rayonne, which means 'ray of light', because of the brightness of rayon fabrics.
History
Rayon was the first generation of cellulosic fibers. It was first known as artificial silk or wood silk, but the term rayon was adopted in 1924. The development of rayon is attributed to the efforts of Sir Joseph Swan, a British scientist, who created the first artificial fiber.
Production
Rayon is produced by dissolving cellulose in a solution of chemicals, typically sodium hydroxide and carbon disulfide, and then extruding it through a spinneret into a bath of sulfuric acid, resulting in the formation of rayon filaments. This process is known as the viscose process.
Uses
Rayon is used in a variety of textile applications, including clothing, home furnishings, and industrial products. It is also used in the production of tires, where it provides strength and flexibility.
