Viscose Rayon — The First Artificial Fiber from Wood Cellulose

In 1892, English chemists Charles Frederick Cross, Edward John Bevan, and Clayton Beadle patented the viscose process — a method of dissolving wood cellulose and regenerating it as continuous filaments that could be woven like silk. By 1905, Courtaulds in Coventry had scaled the process to commercial production. Viscose rayon was the first artificial fiber to compete successfully with natural silk, cotton, and wool — and it was made from wood pulp, one of the cheapest raw materials on earth.

The chemistry is a controlled destruction and reconstruction of cellulose. Wood pulp is treated with sodium hydroxide to form alkali cellulose, then reacted with carbon disulfide to form cellulose xanthate — an orange, honey-thick liquid called 'viscose.' This viscose is aged, filtered, and forced through tiny holes in a spinneret (a metal plate with thousands of sub-millimeter holes) into a sulfuric acid bath that regenerates the cellulose as solid filaments. The filaments are stretched, washed, and wound — the result is a smooth, lustrous fiber with many of silk's properties at a fraction of its cost.

Viscose rayon broke a fundamental assumption that had governed textiles for 10,000 years: that useful fibers must come from plants or animals. For the first time, humans manufactured a textile fiber from molecular components rather than harvesting it from nature. Rayon opened the door to nylon (1935), polyester (1941), and every synthetic fiber that followed. The modern wardrobe — blended fabrics, stretch materials, performance textiles — descends from Cross, Bevan, and Beadle's decision to dissolve a tree and spin it into thread.
