The Fundamentals of Viscose Material

Viscose is a versatile fabric with unique properties. It offers a blend of natural and synthetic features, making it popular in fashion and home textiles.

Definition and Chemical Composition

Viscose, also known as rayon, is a semi-synthetic material made from cellulose fibres. These fibres come from wood pulp or other plant sources.

The production process involves treating cellulose with chemicals to create a liquid solution. This solution is then extruded through tiny holes and solidified into fibres.

Chemically, viscose is similar to cotton. Both are made of cellulose. But viscose undergoes more processing, giving it different properties.

History and Evolution

Viscose was first developed in the late 19th century. It was created as a cheaper alternative to silk.

The fabric gained popularity in the 1920s and 1930s. It was often called artificial silk due to its silky feel and appearance.

Over time, production methods improved. This led to better quality viscose fabrics.

Today, viscose is widely used in clothing, home furnishings, and industrial applications.

Comparison with Other Fabrics

Viscose shares qualities with both natural and synthetic fabrics.

Like cotton, it’s breathable and absorbent. But it’s softer and drapes more like silk.

Compared to polyester, viscose is more comfortable in warm weather. It doesn’t trap heat like synthetic fabrics do.

Viscose is less durable than many natural fibres. It can shrink or lose shape when wet.

Here’s a quick comparison:

Viscose offers a unique blend of properties. It combines the comfort of natural fibres with some benefits of synthetics.

Production Processes of Viscose

Viscose production involves complex chemical processes that transform wood pulp into a versatile textile. The journey from raw materials to finished fabric requires careful handling and precise manufacturing steps.

Raw Materials and Their Sourcing

Wood pulp from fast-growing trees like beech, pine, and eucalyptus serves as the primary source of cellulose for viscose. These trees are chosen for their rapid growth and high cellulose content.

Manufacturers often source wood from managed forests to ensure sustainability. The wood is harvested and processed into pulp, which is then cleaned and bleached.

The quality of the wood pulp directly affects the final viscose fabric. Higher-grade pulp results in smoother, more durable viscose.

Viscose Production Methodology

The production of viscose begins with treating wood pulp with sodium hydroxide. This creates alkali cellulose, which is then pressed, shredded, and aged.

Next, the material is treated with carbon disulfide to form cellulose xanthate. This yellow substance is dissolved in more sodium hydroxide to create a viscous orange solution known as viscose.

The viscose solution is then forced through spinnerets into an acid bath. This process, called regeneration, transforms the liquid back into solid cellulose fibres.

Finally, these fibres are spun into yarn, which can be woven or knitted into fabric.

Environmental Considerations

Viscose production has traditionally had a significant environmental impact due to the chemicals used in the process. Carbon disulfide and sodium hydroxide can be harmful if not properly managed.

Many manufacturers are now adopting closed-loop systems to reduce chemical waste. These systems recycle and reuse chemicals, minimising environmental harm.

Some companies are developing eco-friendly viscose alternatives. These use organic compounds or mechanical processes to break down cellulose, reducing the need for harsh chemicals.

Water usage is another concern in viscose production. Modern facilities often implement water recycling systems to decrease consumption and pollution.

Physical Properties of Viscose Fabrics

Viscose fabrics have unique physical qualities that make them popular in clothing and textiles. These properties affect how the fabric feels, looks, and holds up over time.

Texture and Comfort Level

Viscose fabrics are known for their soft, smooth texture. They feel cool and silky against the skin, making them comfortable to wear. The material is highly breathable, allowing air to flow through easily. This helps keep the wearer cool in warm weather.

Viscose is also very lightweight. Clothes made from this fabric drape well on the body without feeling heavy or restrictive. This makes viscose ideal for flowing dresses and loose-fitting tops.

One downside is that viscose can wrinkle easily. Garments may need ironing or steaming to maintain a crisp appearance.

Aesthetics and Drape Quality

Viscose fabrics have a lovely lustre that can mimic the sheen of silk. They come in both matte and glossy finishes, depending on how they’re made. This versatility allows for a wide range of looks.

The material drapes beautifully, falling in soft folds. It moves gracefully with the body’s movements. This quality makes viscose popular for evening wear and elegant daytime outfits.

Viscose takes dye well, resulting in vibrant, long-lasting colours. However, it may fade if exposed to strong sunlight for long periods.

Durability and Care Instructions

While viscose has many positive qualities, it’s not the most durable fabric. It can weaken when wet and may shrink or stretch out of shape if not cared for properly.

To keep viscose items looking their best:

• Use mild detergent and cool water for washing
• Avoid wringing or twisting the fabric
• Lay flat or hang to dry
• Iron on low heat if needed

Some viscose garments may require dry cleaning to maintain their shape and finish. Always check the care label for specific instructions.

With proper care, viscose items can last for several years. However, they may not be as long-lasting as some natural fibres like cotton or wool.

Ecological Impact and Sustainability

Viscose production raises environmental concerns due to its resource-intensive process and chemical use. The industry is exploring more sustainable options and improved recycling methods.

The Eco-Friendly Debate

Viscose is made from regenerated cellulose, typically sourced from trees. This plant-based origin might seem eco-friendly, but the reality is more complex.

The production process uses harsh chemicals and large amounts of water. It often leads to pollution and can harm workers’ health.

Deforestation is another major issue. Many viscose manufacturers source wood from endangered forests, threatening ecosystems and wildlife habitats.

Some companies are working to improve their practices. They’re using more sustainable wood sources and cleaner production methods. But progress is slow, and less than 30% of viscose is sustainably sourced.

Sustainable Alternatives

The textile industry is developing more eco-friendly viscose alternatives. These aim to reduce environmental impact while maintaining fabric quality.

Lyocell is a promising option. It’s made using the Lyocell process, which:

• Uses non-toxic chemicals
• Recycles water and solvents in a closed-loop system
• Produces minimal waste

Tencel is a branded form of Lyocell. It’s known for its softness and strength.

Bamboo viscose is another alternative. Bamboo grows quickly and doesn’t need pesticides. But the processing still uses harmful chemicals.

These options are steps in the right direction. But they’re often more expensive than traditional viscose.

Biodegradability and Recycling

Viscose is biodegradable, which seems positive for the environment. But it’s not that simple.

The fabric can take 20 to 200 years to fully decompose. During this time, it may release harmful chemicals into the soil.

Recycling viscose is challenging. The fibres often become too weak to reuse after processing. This leads to most viscose products ending up in landfills.

Some companies are developing new recycling methods. These aim to turn old viscose into new fabric. But these technologies are still in early stages.

Consumers can help by choosing products made from recycled or sustainably-sourced viscose. They can also look for certifications that guarantee more eco-friendly production methods.
