A History of Synthetics: Rayon

I'm running a mini-series this week on synthetic fabrics. I originally intended a single post on "A brief history of synthetics", but as I researched it became clear that it wouldn't all fit into one post!

Although not a true synthetic, Rayon is the first man-made fibre. It's made from naturally occurring cellulose (usually from specially processed wood pulp). Because of the chemical processes involved in its production it is classed as a semi-synthetic or artificial fibre, and is generally considered the precursor to all true synthetic fibres.


Rayon can claim a heritage dating back to the 1850s, when Swiss chemist Georges Audemars invented the first crude artificial silk by dipping a needle into a solution of mulberry bark pulp and gummy rubber to make threads. Other chemists developed further techniques over the next few decades, but none were efficient enough to make the new fibre a financially viable alternative to real silk.

In 1894, British inventor Charles Cross, together with Edward Bevan and Clayton Beadle, patented a practical method of making artificial silk. They named their product "viscose" because their processing of the cellulose gave a highly viscous solution, which was then passed through a spinneret to form fine filaments (the scientifically minded can read a more detailed description of the manufacturing process). This chemical-intensive process is not very environmentally sound, unfortunately, though steps have been made in modern production to reduce the impact.

An alternative method of processing natural cellulose into a man-made fibre using acetone was developed by Swiss brothers, Doctors Camille and Henri Dreyfus. In 1905, Camille and Henri developed a commercial process to manufacture cellulose acetate. The brothers initially focused on cellulose acetate film, which was then widely used in celluloid plastics and film. By 1913, Camille and Henri's studies and experiments had produced excellent laboratory samples of continuous filament acetate yarn. In 1918 acetate (a.k.a. cellulose acetate or acetate rayon) fibre was first manufactured in quantity at the British Celanese plant in Derbyshire, England.

The advert above is from a 1915 magazine, and although I can't be sure, I believe this "Opaline" is a trade name for an early rayon fabric.

The first commercial viscose rayon was produced in the UK by Courtaulds in 1905, and in America in 1910 by the American Viscose Company. DuPont Chemicals acquired the rights to the process in the 1920s and quickly turned rayon (The term "rayon" was first used in around 1924) into a household name.

There are two varieties of viscose rayon fibre. Filament rayon is produced in the form of a continuous thread and can be used for fabrics to resemble silk. Spun rayon consists of short filaments twisted (spun) together into a yarn similar to cotton or linen, and is turned into fabrics to resemble these.

By the 1930s rayon was available in a profusion of different fabrics - plain satin, shadow print satin, crepes, velvet, Jacquard, taffeta, shantung, chamois, sharkskin, pique, boucle, gabardine, chiffon, voile, faille - rayon could do anything the natural fibres could.

Rayon in both filament and spun forms has a beautiful soft drape, which helped cement its popularity in the drape-loving 1930s through the early 40s Swing era.

During the war Rayon was one of the Utility fabrics available through cloth rationing.

Acetate rayon is particularly suited to satins and taffetas, so really came into its own in the 1950s when fabrics with more body were required for the full-skirted silhouette of Dior's New Look.

Rayon is the most absorbent of all cellulose fibers, even more so than cotton and linen. Because of this, rayon absorbs perspiration and allows it to evaporate away from the skin, making it an excellent summer fabric. Its high absorbency applies equally to dyes, allowing beautiful, deep, rich colours.

Rayon is a good conductor and poor insulator, furthering its usefulness in hot climates.

It loses a great deal of strength when wet. Because of this it must be handled carefully when washed, and it is also more prone to stretching and shrinkage than cotton. Spun Viscose rayon fabrics shrink more with repeated laundering than fabrics made of the filament yarns.

Rayon lacks the elasticity and resilience of wool and silk and tends to crease easily.


Fiber Identification (information from

In the burning test, rayon most resembles cotton. It ignites rapidly, sometimes even faster than cotton, burning with a large, bright, yellow flame. Burnt rayon leaves an odour like burnt paper, similar to cotton. The ash is also like cotton: light and feathery gray, which disintegrates rapidly.

In the feeling test, rayon is more difficult to identify. The variety of processes, modifications of technique and various treatments can make rayon look and feel like silk, cotton, wool or linen. In general, however, rayon has the smooth felling of silk. It is slippery because of the smoothness of the filaments, and has an almost brittle-feeling quality due to the fiber's inelasticity.

The breaking test can differentiate between rayon, cotton and linen yarns. Because of its inelasticity, rayon will tend to break shortly, with a short, uneven breaking pattern. It is even easier to distinguish when wet, as it breaks very easily then.

  1. This is really interesting and informative, thank you so much for such a great post. Will incude it next time I do a post round-up if you don't mind! :)

  2. Fab post - interetsing & informative! :) Thanks for sharing!

  3. the various 'types' of rayon fabrics boggles my mind sometimes. I think I've come across vintage dresses with every possible texture. Anyway, very informative post. Thanks!

  4. This is really interesting. I am usualy put off buying mad mad fabric. But after reading this i am quit tempted by it. I look forward to the next edition to the series!

  5. Thanks for posting all the full-color ads. I like knowing what color clothes were, since most films (and magazines) are black-and-white. Great information on rayon. I learned a lot!

  6. Oddly enough, I was just re-reading the section on rayon yesterday evening in Claire Schaeffer's "Fabric Sewing Guide", so how apropos that I should find your post this morning! :) Great information--thank you so much for writing this up and sharing!

  7. great post, and thanks for sharing colored magazine images along with the very useful info!

  8. Great post! My late grandfather worked at a Celanese plant in late 40's and supposedly there's a trunk of fabric he brought home over the years somewhere in his house....We may finally discover it 2 years from now who knows!

  9. Wow, thanks for sharing the fruits of your research! Rayon faux silk fabrics always remind me of my grandmother's mid-century home-- so much of her clothing and many decorative items were done up with the shiny stuff.

  10. I've really enjoyed reading this! I love sewing with rayon, it's such a wonderful fabric to work with. It's my Mum's favourite fabric too, living in Australia, she finds it the best for our hot summers.

  11. Wonderful! I was such a textiles nerd in college, I was quite mad we didn't dive into it as much as I wanted. Great post.

  12. Thanks for that so much of exactly the information I was hoping to find.


I'd love to hear your thoughts!
