rayon

Rayon was coined in 1924 at a meeting of the American textile industry, replacing the earlier name 'artificial silk.' The word comes from French rayon (beam of light, ray), chosen because the fabric had the lustrous sheen of silk. Kenneth Lord of Galey & Lord is often credited with proposing the name. The industry wanted a word that sounded natural and appealing, not industrial and chemical. 'Artificial silk' was accurate but unromantic. 'Rayon' was romantic but inaccurate — the fiber has nothing to do with light.

The technology behind rayon was developed in the 1890s. French chemist Hilaire de Chardonnet patented a process for dissolving cellulose (from wood pulp or cotton linters) and extruding it through tiny holes to form fibers. This was not synthesis — it was reconstitution. The cellulose is natural; the process of dissolving and reforming it is industrial. Rayon is a semi-synthetic fiber, sitting between natural fibers (cotton, silk) and fully synthetic ones (nylon, polyester).

Rayon production expanded rapidly in the early 20th century. It was cheaper than silk and could be made in any quantity. The viscose rayon process, developed by Charles Cross and Edward Bevan in 1892, became the dominant manufacturing method. The word viscose (from Latin viscosus, meaning sticky — referring to the treacle-like cellulose solution) became an alternative name for rayon in many countries. In Britain, the fabric is called viscose. In America, it is called rayon. Same material, different marketing.

Environmental concerns have complicated rayon's reputation. The viscose process uses carbon disulfide, a toxic solvent. Modern alternatives like lyocell (branded as Tencel) use less toxic solvents and closed-loop manufacturing. The word rayon now competes with viscose, lyocell, modal, and bamboo rayon — all variations of regenerated cellulose with different brand names and environmental profiles.
