    Swiss chemist Matthias Eduard Schweizer (1818–1860) discovered that cellulose dissolved in … See more

    Process

    Rayon is produced by dissolving cellulose, then converting this solution back to insoluble fibrous cellulose. Various processes have been developed for this regeneration. The most common methods for creatin… See more

    Structural modification

    The physical properties of rayon remained unchanged until the development of high-tenacity rayon in the 1940s. Further research and development led to high-wet-modulus rayon (HWM rayon) in the 1950s. Research i… See more

    Producers and brand names

    In 2018, viscose fiber production in the world was approximately 5.8 million tons, and China was the largest producer with about 65% of total global production. Trade names are used within the rayon industry to label the ty… See more

    Environmental impact

    The biodegradability of various fibers in soil burial and sewage sludge was evaluated by Korean researchers. Rayon was found to be more biodegradable than cotton, and cotton more than acetate. The more water-repellent th… See more

    Controversy

    Studies have found the production of rayon can be harmful to the health of factory workers. Workers in factories utilizing the viscose process may be exposed to high levels of carbon disulfide, which can cause coronary h… See more
