Rayon

Rayon is a synthetic fiber made from natural sources such as wood and agricultural products. It is known for its silk-like feel and is often used in the production of textiles and clothing.

History

Rayon was first developed in the late 19th century by French scientist Count Hilaire de Chardonnet, who was looking for a cheaper alternative to silk. The first commercial production of rayon began in the early 20th century.

Production

The production of rayon involves the treatment of cellulose with caustic soda and carbon disulfide. This process transforms the cellulose into a soluble compound, which is then spun into fibers. The fibers are then washed and treated to remove any remaining chemicals.

Properties

Rayon is known for its silk-like feel and drape. It is highly absorbent and dyes easily, making it a popular choice for clothing and home furnishings. However, it is not as durable as other synthetic fibers and can be prone to shrinking and wrinkling.

Uses

Rayon is used in a wide range of products, from clothing and home furnishings to industrial products like tire cord and surgical sutures. It is also used in the production of nonwoven fabrics, which are used in products like diapers and wipes.

Environmental Impact

The production of rayon has been criticized for its environmental impact. The process uses large amounts of water and energy, and the chemicals used can be harmful to the environment if not properly managed. However, because rayon is made from renewable resources, it is considered more sustainable than other synthetic fibers.
