What Is Viscose Fabric?

Viscose fabric is a semi-synthetic textile made from regenerated cellulose fibers, usually derived from wood pulp — most commonly from beech, pine, or eucalyptus trees. It’s part of the rayon family, which also includes modal and lyocell.

Although it’s plant-based, viscose isn’t considered a natural fiber like cotton or linen because it undergoes a chemical process to turn raw cellulose into a soft, wearable material. In other words, viscose sits between natural and synthetic it’s not entirely organic, but it’s not fully man-made either.

Viscose is loved for its silky appearance and feel, earning it the nickname “artificial silk.” It drapes beautifully, breathes well, and feels smooth on the skin, which makes it a favorite for lightweight garments, linings, and flowy dresses.

A Brief History of Viscose

The story of viscose begins in the late 19th century, during a time when silk was extremely expensive and accessible only to the wealthy. Scientists started experimenting with ways to create a cheaper silk alternative using cellulose — the structural component of plant cell walls.

In 1891, British scientists Charles Cross, Edward Bevan, and Clayton Beadle patented a process to dissolve cellulose using chemicals like sodium hydroxide and carbon disulfide. The resulting viscous solution (hence the name viscose) could be spun into fibers that resembled silk.

By the early 1900s, viscose rayon was being produced commercially, and by the 1920s, it became a fashion industry favorite. It offered the luxurious look and feel of silk without the high price tag. Over the decades, viscose continued to evolve and remains one of the most versatile fibers in the textile world today.

How Is Viscose Fabric Made?

The production of viscose involves both natural materials and chemical processing. Here’s a simplified version of how it’s made:

1. Cellulose Extraction:
   Wood pulp (or sometimes bamboo pulp) is extracted from trees and purified to obtain nearly pure cellulose.

2. Steeping:
   The cellulose is soaked in sodium hydroxide (caustic soda), turning it into alkali cellulose.

3. Pressing and Shredding:
   The alkali cellulose is pressed to remove excess liquid, then shredded into white flakes.

4. Aging:
   The flakes are left to age under controlled conditions, which helps break down the cellulose chains.

5. Xanthation:
   The aged cellulose reacts with carbon disulfide, forming cellulose xanthate — an orange-colored compound.

6. Dissolving:
   The cellulose xanthate is dissolved in a diluted sodium hydroxide solution, producing a thick, honey-like liquid known as viscose solution.

7. Filtration and Degassing:
   The viscose solution is filtered and treated to remove air bubbles, ensuring a smooth final fiber.

8. Spinning:
   The solution is forced through fine spinneret nozzles into a sulfuric acid bath, which solidifies the strands into fibers.

9. Washing and Cutting:
   The new fibers are washed, bleached, and sometimes cut into shorter lengths to be spun into yarns.

This process results in soft, shiny fibers that mimic silk, but can be produced much more affordably.

Common Uses of Viscose Fabric

Because viscose is so adaptable, it’s used in a wide range of industries:

1. Fashion and Apparel

Viscose is often used in:

• Blouses, dresses, and skirts

• Lining fabrics

• Scarves and shawls

• T-shirts and activewear blends

• Evening wear and formal dresses

It’s especially loved in summer collections for its breathability and soft drape.

2. Home Textiles

Viscose also finds a place in interiors:

• Curtains and drapes

• Upholstery blends

• Bed linens

• Cushion covers

The fabric’s sheen adds a touch of luxury to home décor.

3. Industrial Uses

Beyond clothing, viscose is used in:

• Tire cords

• Medical supplies (like surgical dressings)

• Cellophane production (a related process)

Advantages of Viscose Fabric

Here are the reasons viscose remains so popular worldwide:

1. Soft and Comfortable

Viscose is exceptionally smooth, lightweight, and breathable — qualities that make it perfect for garments that touch the skin directly.

2. Beautiful Drape

Its fluid, elegant drape makes viscose ideal for flowing dresses, skirts, and scarves. It moves naturally and flatters many body types.

3. Affordable Alternative to Silk

Viscose mimics silk’s appearance and texture at a fraction of the cost, making it a budget-friendly luxury option.

4. Highly Absorbent

Viscose can absorb up to 50% more moisture than cotton, which helps wick away sweat and keeps the wearer cool.

5. Vibrant Colors

The fiber’s structure allows it to hold dyes well, resulting in bright, long-lasting hues.

6. Versatile

Viscose blends easily with other fibers like cotton, polyester, or spandex, combining their strengths for enhanced performance.

Disadvantages of Viscose Fabric

Despite its many benefits, viscose has some downsides that are important to understand:

1. Wrinkles Easily

Viscose creases quickly, especially after washing or sitting for long periods. It often needs ironing or steaming to maintain a polished look.

2. Weak When Wet

The fabric loses strength when wet, making it prone to shrinking, stretching, or tearing during washing if not handled carefully.

3. Environmental Concerns

Traditional viscose production involves harsh chemicals like carbon disulfide, which can harm workers and pollute waterways if not properly managed.

4. Not Very Durable

Over time, viscose may show signs of wear — especially in areas that experience friction or repeated washing.

5. Can Shrink or Lose Shape

If exposed to high heat or improper washing, viscose can shrink or distort easily.

Is Viscose Sustainable?

Sustainability is one of the biggest debates surrounding viscose. On the surface, it seems eco-friendly since it’s made from renewable wood pulp. However, the traditional viscose process uses toxic chemicals and large amounts of water and energy.

In the past, viscose factories were linked to deforestation and pollution in developing countries. However, modern innovations have led to more sustainable forms of viscose, including:

• EcoVero™ by Lenzing: Made from sustainably sourced wood with a closed-loop system that recovers chemicals and reduces emissions.

• Bamboo Viscose: Produced from bamboo pulp (though not all bamboo viscose is truly eco-friendly — it depends on the production method).

• Lyocell (Tencel™): A next-generation fiber similar to viscose but made using a non-toxic solvent in a closed-loop system.

When shopping, look for certifications like OEKO-TEX®, FSC®, or Lenzing EcoVero™, which indicate better environmental practices.

How to Care for Viscose Fabric

Because viscose is delicate when wet, it requires gentle care to maintain its beauty and longevity. Here are some care tips:

1. Read the Label: Always check the garment care instructions. Some viscose items are dry-clean only.

2. Hand Wash (If Allowed): Use cold or lukewarm water with mild detergent. Avoid twisting or wringing.

3. Avoid Hot Water: High temperatures can cause shrinking or distortion.

4. Dry Flat: Lay the garment flat on a towel to air dry. Avoid hanging while wet to prevent stretching.

5. Iron Carefully: Use a low to medium heat setting while the fabric is slightly damp. You can also steam to remove wrinkles.

6. Store Properly: Keep viscose garments in a cool, dry place away from direct sunlight to prevent fading.

With the right care, viscose garments can stay beautiful for years.
