This fabric is incredibly versatile, finding its way into numerous products we use daily, from our favorite clothes to cozy home furnishings.

Rayon is semi-synthetic, a characteristic that sets it apart from both natural fibers like cotton and fully synthetic ones like polyester. This means that while it’s made from naturally occurring cellulose, the process of transforming this cellulose into usable rayon fibers involves chemical alterations, making it a man-made fiber.

A Brief History of Rayon Fibers

The journey of rayon began in the 1860s when the French silk industry was grappling with a crisis due to a disease affecting silkworms. The quest to save the industry-led Louis Pasteur and Count Hilaire de Chardonnet to study this problem, and it was during this time that the idea of creating artificial silk was conceived.

Chardonnet, in 1885, patented the first successful method to manufacture rayon from cellulose, marking the birth of what was initially called artificial or imitation silk.

For the next several decades, this innovative fabric was known as artificial silk until 1925, when the Federal Trade Commission (FTC) officially named it rayon, a term encompassing any man-made fiber derived from cellulose.

History of Rayon Fibers

Rayon production evolved, and by the 1950s, most rayon produced was primarily used in industrial and home furnishing products, with regular rayon, also known as viscose rayon, being considered weaker compared to other fibers used for clothing.

However, the rayon journey didn’t stop there. In 1955, the production of a new type of rayon, high-wet-modulus (HWM) rayon, began. HWM rayon was stronger and more versatile, suitable for making sheets, towels, and apparel. This innovation is considered the most significant development in rayon production since its invention in the 1880s.

Today, rayon fabrics are globally produced and are among the most widely used fabrics.

How is Rayon Fabric Made?

Creating rayon fabric is a fascinating journey. It begins with the extraction of cellulose and ends with the transformation of this natural polymer into versatile fibers.

Let’s delve into this process and understand how rayon, with its many properties similar to natural fibers, is crafted.

Extracting Cellulose: The First Step

The creation of rayon fabric starts with the extraction of cellulose, a complex carbohydrate found in the cell walls of plants.

How is Rayon Fabric Made

This cellulose is typically derived from wood pulp, with various types of wood being used, depending on the desired properties of the final product. The process involves purifying the wood pulp to obtain pure cellulose, which serves as the foundational material for producing rayon fibers.

This purified cellulose is then treated to form alkali cellulose, a crucial intermediate product in the production of rayon.

Transforming Cellulose: The Chemical Process

Once we have alkali cellulose, the journey to create rayon fabric enters its next phase: the chemical transformation of cellulose into rayon. This involves a series of chemical reactions where the alkali cellulose is treated with carbon disulfide to form cellulose xanthate, a yellow crumbly substance.

This cellulose xanthate is then dissolved in a solution, leading to the formation of viscose rayon fiber.

The transformation of plant cellulose into regenerated cellulose fibers, or rayon, is a meticulous process, and it raises several environmental concerns. The chemicals used in this process, such as carbon disulfide, are hazardous and can have detrimental impacts on the environment and human health.

This aspect of rayon production has sparked discussions and innovations aimed at making the process more sustainable and less harmful.

Whether it’s the softness of viscose rayon or the strength of other types of rayon, the ability to engineer these properties through the manipulation of cellulose is a testament to the advancements in material science and technology.

The advantage of using high wet modulus rayon lies in its ability to maintain integrity and structure even in damp conditions, unlike regular rayon, which tends to weaken when wet.

However, it’s essential to note that while HWM rayon offers enhanced strength, it may not be as soft as other types of rayon, which can be a disadvantage depending on the intended use.

2. Viscose Rayon

Viscose rayon is perhaps the most common type of rayon and is renowned for its silk-like feel and drapability.

It’s a fabric that’s widely used in clothing, offering a luxurious touch and appearance. Viscose fabric is highly absorbent and breathable, making it a favorite for summer wear.

However, viscose rayon has its set of challenges, primarily its tendency to weaken when wet and its environmental impact due to the chemicals used in its production. The production of viscose rayon requires careful consideration of environmental and ethical practices to mitigate its impact on our planet.

3. Modal and Lyocell

Modal and lyocell are modern innovations in the world of rayon, offering enhanced properties and a more sustainable production process.

These fabrics are known for their softness, strength, and excellent moisture-wicking properties, making them suitable for activewear and intimate apparel.

What sets modal and lyocell apart is their environmentally friendly production process, utilizing closed-loop systems that significantly reduce chemical waste and water usage. These sustainable practices make modal and lyocell more aligned with our values of ecological responsibility and conscious living.

4. Cuprammonium Rayon

Cuprammonium rayon is another intriguing variant of rayon, crafted from cellulose dissolved in a cuprammonium solution, also known as Schweizer's reagent.

This type of rayon is produced by transforming cellulose into a soluble compound, combining it with copper and ammonia, along with caustic soda. The resulting solution is then passed through a spinneret, and the cellulose is regenerated in hardening baths. These baths serve to remove the copper and ammonia and neutralize the caustic soda, leaving behind fine filaments.

This rayon is typically crafted into fine filaments, ideal for lightweight summer dresses and blouses.

It’s often blended with cotton to create textured fabrics with slubbed, uneven surfaces, offering a unique aesthetic and feel. Known by trade names like "Bemberg," owned by the J.P. Bemberg company.  

These are sometimes referred to as "cupro" or "cupra," this fabric is also recognized as "ammonia silk" on various Chinese fashion retail websites.
