Viscose, also known as rayon in some regions, is a semi-synthetic fabric first developed in the late 19th century as a more affordable alternative to silk. Made from cellulose derived from wood pulp, viscose undergoes a chemical process that transforms it into a versatile fiber. The production of viscose involves dissolving cellulose in a chemical solution, which is then extruded through a spinneret and solidified to form fibers. This process allows for the creation of threads that are not only smooth and lightweight but also highly absorbent.

Compared to natural fibers like cotton, viscose offers a distinctively smooth texture and a lustrous finish, making it highly desirable for garments that require a soft, draped look. However, unlike synthetic fibers such as polyester, viscose is not inherently strong or durable, which poses unique challenges and considerations for garment manufacturers.

Properties of Viscose Fabric

Viscose fabric is celebrated for its unique properties that make it particularly appealing in the fashion industry. Here are some of the key characteristics:

  • Texture and Weight: Viscose is known for its soft, smooth texture that closely mimics fine silk. It’s generally lightweight, making it ideal for flowing dresses, blouses, and scarves that require a fluid, elegant drape.
  • Comfort and Durability: While viscose is comfortable against the skin due to its breathable nature and moisture-absorbent qualities, it does have some limitations in durability. It tends to be less resistant to wear and tear compared to more robust fibers like cotton or polyester, especially when wet.
  • Absorbency and Dye Affinity: One of the most valued properties of viscose is its high absorbency, which allows it to take dyes deeply and retain vibrant colors over time. This makes it a popular choice for producing richly colored garments.

How is Viscose Fabric Made

The process of making viscose involves several steps that transform natural materials into a versatile fiber. Here’s a step-by-step overview of how viscose is made:

1. Sourcing Cellulose

Viscose is made from cellulose, which is derived from wood pulp. Common sources include trees like eucalyptus, beech, pine, and sometimes bamboo. The wood pulp is obtained through a process that involves chipping wood and treating it with chemicals to break it down into a pulp.

2. Purifying the Cellulose

The wood pulp is treated and purified to remove any impurities, leaving behind a bright white cellulose product. This pure cellulose is what will be dissolved to form the viscose solution.

3. Dissolving the Cellulose

The purified cellulose is soaked in a solution of sodium hydroxide (caustic soda), which turns it into alkali cellulose. This alkali cellulose is aged under specific conditions of time and temperature to prepare it for the next step.

4. Xanthation

The alkali cellulose is treated with carbon disulfide, converting it into cellulose xanthate, which is a yellowish, highly viscous substance. This process is what gives viscose its name, derived from the “viscous” nature of the cellulose xanthate solution.

5. Dissolving Cellulose Xanthate

The cellulose xanthate is dissolved in a dilute solution of sodium hydroxide, resulting in a thick, viscous solution known as viscose. This solution is filtered to remove any undissolved particles and then degassed to eliminate any air bubbles that could interfere with the spinning process.

6. Spinning

The viscose solution is extruded through a spinneret into an acid bath containing sulfuric acid and other salts. This coagulates the viscose, regenerating it into cellulose filaments and setting the fibers. This step is crucial as it turns the viscose solution back into a solid form of cellulose, now in fiber form.

7. Drawing

The fibers are stretched, or “drawn,” which aligns the cellulose molecules and increases the tensile strength, making the fibers more durable. This step is important for enhancing the performance characteristics of the viscose fibers.

8. Washing and Finishing

The newly formed viscose fibers are washed thoroughly to remove any remaining chemicals and impurities. After washing, the fibers may be treated with various finishing agents to achieve desired properties like softness, luster, or resistance to bacteria.

9. Cutting and Baling

Finally, the fibers are cut to a desired staple length if they are to be blended with other fibers or left as continuous filaments, depending on the end-user. They are then baled and shipped to fabric manufacturers to be woven or knitted into viscose fabric.

The process of making viscose is quite chemical-intensive, which has led to environmental concerns. However, recent innovations in manufacturing technology are aiming to make this process more sustainable, such as the development of the Lyocell process, which uses less harmful solvents and recycles the water and solvents used in production.

What Different Types of Viscose Are There?

Viscose, a versatile and popular fabric in the fashion industry, comes in various types, each with specific characteristics and applications. Here’s an overview of the different types of viscose you might encounter:

Ryan And Viscose

There’s a subtle difference between viscose and rayon:

Rayon: A broader term encompassing various types of fabrics made from regenerated cellulose, including viscose. Think of rayon as a category, like “fruit. “
Viscose: The most common type of rayon, known for its silk-like feel. It’s like a specific type of fruit, ” apple” within the category of “fruit. “

Both viscose and other rayon types share some commonalities:

Made from natural sources (wood pulp)
Semi-synthetic due to the chemical processing involved
Soft, breathable, and comfortable
So, you might see “viscose rayon” or simply “rayon” on clothing labels. In most cases, they’re referring to viscose. But if you’re looking for more specific information about the fabric, checking for terms like “modal rayon ” or “lyocell rayon” can help identify the exact type used.
