Viscose fabric, often referred to as one of the most versatile and luxurious textiles, holds a prominent place in the fashion and textile industries. With its silky texture, excellent drape, and affordability, it has become a staple in both high-fashion and everyday apparel. 

However, the story of viscose is much more complex than just its aesthetic appeal. 

From its historical roots to its modern-day applications, this guide will take you through everything you need to know about viscose fabric, including its production process, characteristics, environmental impact, and much more.

What is Viscose Fabric?

Viscose, also known as rayon in some regions, is a semi-synthetic fabric that falls between natural and synthetic fibers. 

It is made from cellulose, a natural polymer found in plant cell walls, but undergoes extensive chemical processing to transform it into a usable textile. 

The name "viscose" is derived from the viscous organic liquid used in the process of making the fibers. 

Although it’s been around for more than a century, viscose continues to be a popular choice for many because of its ability to mimic the properties of natural fibers like silk and cotton while remaining affordable.

Characteristics of Viscose Fabric

Viscose is prized for its unique combination of properties, which make it suitable for a wide range of applications. Here are some of the key characteristics that define viscose fabric:

• Softness: Viscose is incredibly soft to the touch, often compared to natural fibers like silk and cotton. This softness makes it comfortable to wear and is one of the reasons why it is so popular in clothing.
• Breathability: The fabric is highly breathable, allowing air to pass through easily. This property makes viscose ideal for warm-weather clothing, as it helps keep the wearer cool and comfortable.
• Drape: One of the most distinguishing features of viscose is its excellent drape. The fabric flows and hangs beautifully, giving garments an elegant and fluid appearance. This makes viscose a favorite for dresses, blouses, and other garments where drape is important.
• Absorbency: Viscose is highly absorbent, capable of holding up to 50% more moisture than cotton. This makes it an excellent fabric for dyes and prints, as it readily absorbs color and produces vibrant, long-lasting hues.
• Versatility: Viscose can be blended with a variety of other fibers, including cotton, wool, and synthetic fibers like polyester. These blends enhance the fabric's properties, such as increasing its durability or improving its elasticity.
• Biodegradability: Since viscose is made from natural cellulose, it is biodegradable under the right conditions. This makes it a more environmentally friendly option compared to many synthetic fabrics.
• Smoothness: Viscose has a smooth, glossy surface that feels luxurious against the skin. This smoothness also contributes to the fabric's high level of comfort.
• Cooling Effect: Viscose has a natural cooling effect, making it a great choice for summer garments. It does not trap heat, allowing the wearer to stay cool even in hot conditions.
• Lustrous Appearance: Viscose has a natural sheen that gives it a luxurious appearance. This luster is one of the reasons why viscose is often used as a substitute for silk.

When did Viscose Fabric Come into Being?

Viscose fabric has a rich history that dates back to the late 19th century, when British scientists Charles Frederick Cross, Edward John Bevan, and Clayton Beadle sought to create an affordable alternative to silk. Silk, a natural fiber, was highly prized for its softness and sheen but was expensive and difficult to produce. The scientists patented their process for making viscose in 1892, marking the beginning of what would become a significant advancement in the textile industry.

The early 20th century saw the commercial production of viscose, which was initially marketed as "artificial silk." However, due to the negative connotations associated with the term "artificial," it was rebranded as "rayon" in the United States and "viscose" in Europe. 

The fabric gained widespread popularity, particularly during World War I, when the demand for cheaper, silk-like materials surged. Today, viscose remains a widely used fabric, appreciated for its versatility and luxurious feel.

How is Viscose Fabric Made?

Viscose production is a complex process that involves transforming wood pulp into a soft, silky fabric. Here's a step-by-step breakdown of how viscose is made:

1. Cellulose Extraction: The process begins with the extraction of cellulose from wood pulp, which is typically sourced from trees like beech, pine, or eucalyptus. These trees are chosen for their high cellulose content and fast growth rates.
2. Alkalization: The extracted cellulose is then treated with sodium hydroxide (caustic soda), which breaks down the cellulose into a more manageable form. This step is crucial for preparing the cellulose for the next phase of the process.
3. Xanthation: In this stage, carbon disulfide is added to the alkali cellulose, transforming it into cellulose xanthate. This substance is characterized by its orange-yellow color and sticky consistency. The name "viscose" originates from the viscous nature of this solution.
4. Dissolution: The cellulose xanthate is dissolved in a mixture of chemicals to create a thick, honey-like solution. This solution is what will eventually be spun into fibers.
5. Filtration: To ensure the purity of the final product, the viscose solution is filtered to remove any impurities. This step is crucial for producing a high-quality fabric.
6. Spinning: The filtered solution is then extruded through a device called a spinneret, which has tiny holes that shape the solution into long filaments. These filaments are immediately solidified by immersing them in an acidic bath, where they become the final viscose fibers.
7. Drawing: The fibers are stretched, or "drawn," to align the cellulose molecules. This increases the strength and flexibility of the fibers, making them suitable for weaving or knitting into fabric.
8. Washing and Cutting: After drawing, the fibers are washed to remove any remaining chemicals. They are then cut into the desired lengths, depending on their intended use. The washed and cut fibers are now ready to be spun into yarn and woven into fabric.

Types of Viscose Fabric

Viscose is not a one-size-fits-all fabric. Over the years, several variations of viscose have been developed, each with its own unique properties. Here are the main types of viscose fabric:

1. Standard Viscose: This is the most common type of viscose and is widely used in clothing, upholstery, and various other textile applications. It offers a good balance of softness, breathability, and affordability.
2. High-Wet-Modulus (HWM) Rayon: Also known as modal, HWM rayon is a type of viscose that has been chemically treated to increase its strength, particularly when wet. This makes it more durable than standard viscose and less prone to shrinking and stretching.
3. Lyocell: Lyocell is a form of viscose that is produced using a closed-loop process, which recycles water and chemicals during production. This makes it a more environmentally friendly option compared to standard viscose. Lyocell is also stronger and more durable, with excellent moisture-wicking properties.
4. Cupro: Cupro is a type of rayon made from cotton linter, the short fibers left behind after the cotton ginning process. It is often used in linings and lightweight garments due to its smooth texture and ability to drape well.
5. Bamboo Viscose: Bamboo viscose is made from bamboo cellulose. It has become popular in recent years due to its sustainability, as bamboo is a fast-growing plant that requires little water and no pesticides. Bamboo viscose is soft, breathable, and has natural antibacterial properties.
6. Viscose Velvet: Viscose can also be used to make velvet, a fabric known for its soft, luxurious texture. Viscose velvet is often used in high-end fashion and home decor items like curtains and upholstery.
7. Viscose Crepe: Crepe viscose has a textured surface and is often used in dresses, blouses, and skirts. It is lightweight and has a slightly crinkled appearance, adding visual interest to garments.
