By Camille Myers Breeze and Tegan Kehoe The name “rayon” was coined in the 1924 as a generic term for regenerated cellulose fiber. The “Father of Rayon,” Frenchman Count Hillaire de Chardonnet, discovered in the 1880s that nitrocellulose from rags or wood pulp could be turned into fiber, thread, and fabric. Rayon was the first manufactured fiber, but because it is derived from cellulose, is not considered to be a true synthetic but a “semi-synthetic.” “Artificial Silk” made by the Chardonnet process was popular for decorative fabrics in the early 20th century.
At the same time, the Courtaulds Company in England commercialized a method of regenerating cellulose fiber, resulting in a new fiber called “viscose.” (so named because their process used a highly viscous solution.) Courtaulds forming a subsidiary in America called American Viscose Company, who began producing rayon in 1910.  A mid-20th-century image of rayon manufacture. A third method of extracting usable fiber from natural cellulose was developed by Swiss brothers, Doctors Camille and Henri Dreyfus, resulting in the 1905 invention of cellulose acetate. The Dryfus brothers turned their new material into cellulose acetate film and plastics before producing usable continuous filaments of acetate yarn in 1913. By 1918 acetate rayon was being manufactured at the British Celanese plant in Derbyshire, England, which lends its name “Celanese” to some of the resulting rayons.  Industrial Rayon Corporation Plant, Life Magazine, 1939. By the turn of the 21st century, 24% of the rayon produced in the world is from Grasim of India, by far the largest manufacturer. Other countries making rayon today include Germany, Brazil, Austria, China, Laos, Canada, and the US. Some critics of the fiber will point to sustainability concerns as well as dirty manufacturing processes. The United States Environmental Protection Agency has banned the manufacturing of cuprammonium rayon, sometimes found under the trade name Bemberg, but it is still made in Italy. Tencel rayon, also known by its generic name "lyocell," was developed in Courtaulds Research in the 1980's as a “non-polluting” alternative. Today, many rayons include bamboo instead of wood pulp. Because bamboo is fast-growing it is often seen as ecologically friendly, but most bamboo rayons are made with the "dirtier" viscose process. The Federal Trade Commission has charged several clothing companies as falsely advertising their rayon as bamboo, partly because it is not clear that the cellulose they use is entirely from bamboo, but also because the FTC feels that the process alters the fibers too much to be considered plant-based. Currently, lyocell is often made with wood pulp from Eucalyptus trees.  While it's no longer cutting-edge technology, rayon is still used today. This is a modern yarn by Blue Heron Yarns.

by Tegan Kehoe This lovely sample of wartime-era yarn was recently donated to the Museum Textile Services study collection by Mig Ticehurst of Keswick, Cumbria, England. Ms Ticehurst emailed us about her old yarn, saying "It seems wrong to throw it away. Is it possible that it would be of interest to you?"  The company that made this yarn has gone by several names, but at the time, it was Robert Glew & Co, Ltd. We love the slogan on the label of this yarn – “Reliable rayon for dainty garments.” Mig quipped that she had this on hand and unused because she’s: “...not that keen on making ‘dainty garments'. As children, knitting was taught in school and we were all obliged to knit as part of the war effort. Our family thing was scarves for merchant seamen which were garter stitch and at the time seemed absolutely huge but probably were about two feet wide and about six feet long. I learned to knit and read by the time I was eight as it was the only way to do any reading. There was also a great deal of inventive making of things."  The pink rayon yarn we were given would be perfect for this toddler dress, in a pattern sold by Robert Glew & Co.The robin on this leaflet cover is the symbol of the yarn company. This pastel yarn is not just for baby clothes--any women who wanted to make “dainty garments” for themselves could afford rayon. The pattern below is probably from the 1940s or 50s-–note the milkshake glass in the woman’s hand! The pattern specifies Robin Perle, which is what’s in our little yarn stash. “Perle” describes any high-sheen, two-ply twisted yarn like this or mercerized cotton.  The hand-tinted black-and-white photo on the front of this pattern leaflet uses a common style of the time, in which only the brand information and the garment are colored. The company logo on our donated yarn indicates that it was manufactured in Bradford, West Yorkshire, England. Bradford has been a textile hub for centuries but became a boom town early on in the Industrial Revolution, achieving prominence as the “wool capital of the world” by the mid-nineteenth century. Products included mohair, alpaca, cotton, and silk textiles. By the early twentieth century, however, Bradford’s hold on the industry had begun to slip, so some companies stayed current by producing the new synthetics.  Robert Glew & Co. later spawned Robin Wools Ltd. of Greengate, Bradford. This pattern features two-ply "Ny-lona," another remarkable 20th-century synthetic fiber. Rayon is still being modified and produced today, and it shows up more places than you might think. Stay tuned for the next two weeks for more blogs about rayon and some other remarkable 20th-century fibers that MTS has been conserving.
