What is Viscose?
Viscose is a unique fabric with interesting origins and properties. It bridges the gap between natural and synthetic materials.
The Nature of Viscose
Viscose is a semi-synthetic fabric made from cellulose, usually from wood pulp. It’s known as a manufactured fibre, but starts with natural materials. The process turns wood into a soft, flowing fabric.
Viscose feels silky and smooth. It drapes well and absorbs dye easily. These qualities make it popular for clothing and home goods.
Though it comes from plants, viscose isn’t considered a natural fibre. The chemical process changes it too much. But it’s not fully synthetic either.
Viscose is breathable and comfortable to wear. It wicks moisture well. But it can shrink or stretch if not cared for properly.
Viscose Vs. Rayon
Viscose and rayon are often confused. Rayon is the broader term for regenerated cellulose fibres. Viscose is a type of rayon.
All viscose is rayon, but not all rayon is viscose. Other types of rayon include modal and lyocell. These differ in how they’re made and their properties.
Viscose was first called “artificial silk” due to its shiny look. It was invented as a cheaper silk alternative. Today, it’s used to mimic cotton and linen too.
Both viscose and other rayons start as wood pulp. But viscose uses more chemicals in production. This makes it less eco-friendly than some other rayons.
The History and Evolution of Viscose
Viscose, also known as rayon, has a rich history spanning over a century. Its development revolutionised the textile industry, offering a more affordable alternative to natural fibres.
Early Developments
The story of viscose begins in the late 19th century. In 1883, French industrial scientist Georges Audemars created viscose as a low-cost alternative to silk. This breakthrough came from the discovery that cellulose could be dissolved and then regenerated into fibres.
British scientists perfected the process in 1892. They patented the method, setting the stage for commercial production. The name ‘viscose’ comes from the sticky, viscous liquid used in its creation.
Early viscose fabric was shiny and smooth, mimicking the luxurious feel of silk. This made it popular for clothing and home textiles.
Advancements in Viscose Production
As the 20th century progressed, viscose production techniques improved. Manufacturers developed new methods to enhance the fabric’s qualities.
In the 1920s, they introduced stronger viscose fibres. This made the fabric more durable and versatile. The textile industry began using viscose for a wider range of products.
Modal and lyocell emerged as new types of rayon. These offered improved strength and softness. Lyocell, in particular, used a more eco-friendly production process.
Today, viscose is the third most-used textile globally. Its popularity stems from its versatility, comfort, and affordability.
Extraction and Production Process
Viscose production involves transforming wood pulp into smooth fibres through chemical processes. The journey from tree to fabric requires several key steps and specialised equipment.
Harvesting Wood Pulp
Viscose rayon starts with wood from fast-growing trees like beech, pine, or eucalyptus. Workers cut down the trees and remove the bark. The wood is then chipped into small pieces and cooked with chemicals. This breaks it down into a mushy pulp.
The pulp goes through cleaning to remove impurities. Machines press out excess water. What’s left is sheets of pure cellulose. These sheets look a bit like thick paper.
Chemical Transformation
The next stage uses strong chemicals to change the cellulose. Workers soak the pulp in sodium hydroxide, also called caustic soda. This creates a substance called alkali cellulose.
The alkali cellulose then reacts with carbon disulphide. This forms a new compound called cellulose xanthate. It has an orange colour and a sticky texture.
Creating the Fibre
The final step turns the cellulose xanthate into actual viscose fibres. Workers dissolve it in more sodium hydroxide to make a thick, honey-like liquid.
This liquid gets forced through tiny holes in a device called a spinneret. As it comes out, it enters an acid bath. The acid makes the liquid solidify into long, continuous strands.
These strands are the viscose fibres. Machines wash, dry, and stretch them. The result is a soft, silky material ready to be woven into fabric.
Characteristics of Viscose Fabrics
Viscose fabrics have unique qualities that make them popular for clothing and home textiles. They offer a mix of comfort, style, and practicality that appeals to many consumers.
Physical Properties
Viscose is known for its softness and comfort. It feels silky against the skin, making it ideal for garments worn close to the body. The fabric is also quite lightweight, which adds to its comfort in warm weather.
One of viscose’s key features is its excellent breathability. It allows air to flow freely, helping to regulate body temperature. This makes it a good choice for summer clothing and bedding.
Viscose fabrics drape beautifully, giving garments a lovely, flowing appearance. They also take dye well, resulting in vibrant colours that tend to last.
Durability and Care
While viscose has many positive attributes, it does require some special care. The fabric is not as durable as some natural fibres and can be prone to shrinking or stretching.
To keep viscose items looking their best, it’s often recommended to dry clean them. If washing at home, use cool water and a mild detergent. Hand washing is usually safest, but some viscose items can be machine washed on a gentle cycle.
Viscose tends to wrinkle easily, so it may need ironing. Use a cool iron setting to avoid damaging the fabric. Proper care can help maintain the fabric’s softness and colour retention over time.
Types of Viscose Fabrics
Viscose comes in many forms, each with unique properties. The fabric can be blended with other materials or woven into different patterns to create varied textures and styles.
Viscose Blends and Variations
Lyocell is a type of viscose made through an eco-friendly process. It’s known for its strength and softness. Modal is another variation, prized for its silky feel and resistance to shrinkage.
Tencel, a brand name for lyocell, is becoming popular due to its sustainability. It’s made from eucalyptus trees and requires less water to produce than cotton.
Viscose can also be blended with natural fibres like cotton or synthetic ones like polyester. These blends combine the best qualities of each material, creating fabrics that are both comfortable and durable.
Popular Weaves
Viscose fabric comes in various weaves, each suited to different uses. Jersey viscose is a knit fabric that’s stretchy and soft, making it ideal for t-shirts and dresses.
Poplin viscose has a plain weave structure, resulting in a smooth, crisp fabric. It’s often used for shirts and blouses.
Viscose can also be woven into twill or satin patterns. Twill viscose has a diagonal pattern and is more durable, while satin viscose has a glossy surface that’s perfect for evening wear.
