What is Rayon (Viscose): A Complete Guide to the Semi-Natural Fiber That Imitates Silk

Introduction

When you say "cactus silk" or "artificial silk," you're actually talking about rayon —or viscose , as it's better known in Europe. It's a fabric that's been a part of our wardrobes for over 100 years and continues to be one of the most popular due to its elegant look, affordable price, and versatility.

Rayon is a unique fiber: it is neither completely natural nor completely synthetic. It falls into the category of semi-natural fibers, because it is made from regenerated cellulose from wood, bamboo or other plants, but goes through a chemical process to be transformed into textile yarn.

In this article you will find out:

• what is rayon and how is it produced,

• what is its history,

• why is it also called viscose,

• what are the benefits and disadvantages,

• what types of rayon exist (including Tencel, Modal and Cupro),

• how to care for rayon clothes,

• and why it remains so appreciated in fashion.

What is Rayon?

Rayon is a semi-synthetic fiber made from regenerated cellulose. In other words, the raw material is natural – wood, bamboo or agricultural residues – but the fiber goes through a chemical process to become yarn that can be woven.

It has the same molecular structure as plant cellulose, which is why it closely resembles natural fibers like cotton or linen. The difference is that rayon can be "molded" to mimic almost anything: silk, wool, cotton, or even linen.

When you touch it, rayon has a smooth, soft, and fluid feel. Sometimes it is so similar to silk that many people call it artificial silk .

The origin and history of rayon

The rayon has a fascinating story that begins at the end of the 19th century.

• 1894 – English chemist Charles Frederick Cross, together with Edward John Bevan and Clayton Beadle, patents "artificial silk".

• Their process involves a very viscous solution, which is why the material was named "viscose".

• 1924 – the name "rayon" appears, adopted especially in the United States.

• In Europe, the name "viscose" continued to be used for the resulting fabric.

Thus, when you hear "rayon", "viscose" or "artificial silk", they all refer to the same type of fiber, but the names differ depending on the region and historical period.

Types of rayon and its relatives

Over time, technology has allowed the creation of several types of rayon, each with specific properties.

Viscose

The most common type. It is soft, shiny, and easy to dye. It is used in dresses, shirts, bed linens, and even curtains.

Modal

Also made from cellulose, but through an improved process. It is more resistant, more elastic and finer than classic viscose. It is widely used in underwear and sportswear.

Copper

Made from cotton linters, it is very soft, with a silky appearance, but skin-friendly and hypoallergenic.

Tencel (Lyocell)

Considered the most environmentally friendly option, Tencel is made from eucalyptus wood and processed through an environmentally friendly process. It is durable, soft and very pleasant to wear.

All these variants are part of the same "family" of semi-natural fibers, having the same base: regenerated cellulose.
