Viscose Fabric: Physical and Mechanical Properties of Viscose

Viscose is a semi-synthetic fabric made from regenerated cellulose, usually derived from wood pulp. It is commonly used in the textile industry for its soft, smooth, and luxurious feel, often resembling silk. The manufacturing process involves dissolving cellulose in a chemical solution to create a viscous liquid, which is then spun into fibers. Viscose is known for being highly absorbent, breathable, and comfortable to wear, with excellent draping qualities. However, it can be less durable when wet and may wrinkle easily. The physical and mechanical properties of viscose largely depend on the way the fiber is shaped. Depending on the production process, the fabric can vary in several ways:

• Glossy or Matt
• Lightweight or Heavy
• Textured or Smooth

100% Viscose closely resembles silk:

• Semi-transparent
• Glossy finish
  • Special matting chemicals are often applied to reduce the natural gloss.

Advantages of Viscose Fabric

Viscose is widely used because of its remarkable qualities. Here are some of its most beneficial traits:

1. Versatility:

   • Viscose blends well with other fibers like cotton, polyester, and wool, which improves its overall performance and appearance.

2. Comfort:

   • Breathable: Allows air circulation, making it comfortable in both hot and cold weather.
   • Soft and smooth: Feels soft against the skin, providing a pleasant wearing experience.
   • Temperature-regulating: Keeps you warm in winter and cool in summer, providing year-round comfort.
   • Drapes well: The fabric flows naturally, making it ideal for clothing like dresses, blouses, and skirts.

3. Color and Dyeing:

   • Easily dyeable: Viscose takes dye easily, producing rich and vibrant colors.
   • Excellent color retention: Viscose holds colors well, and dyed fabrics maintain their appearance over time.
   • The dyeing process allows for maximum color penetration, which prevents fading under sunlight when properly dyed.

4. Absorbency:

   • Viscose is highly absorbent, capable of absorbing up to twice as much moisture as cotton, making it a great fabric for warm-weather garments.

5. Durability:

   • Strong and robust when dry, providing long-lasting wear.
   • Lightweight compared to cotton, making it comfortable and practical for everyday wear.
   • Does not trap body heat: Unlike some other fabrics, viscose doesn't trap excess heat, ensuring you stay comfortable throughout the day.
   • Non-static: Viscose fabric doesn’t build up static electricity, offering a smooth feel when worn.
   • Non-allergenic and hygienic: It’s gentle on the skin, making it suitable for people with sensitivities.
   • Inexpensive: A cost-effective option compared to other high-end fabrics, offering a luxurious feel at a lower price.

Drawbacks of Viscose Fabric

Although viscose offers many benefits, it does have some drawbacks, mostly related to care and wear. However, with proper maintenance, these issues can be minimized.

1. Shrinkage and Deformation:

   • Viscose can shrink when washed, especially if it’s exposed to high temperatures or improperly washed.
   • The fabric may deform and lose its shape after repeated exposure to washing or water.

2. Wrinkling:

   • Viscose is prone to wrinkling, which can require extra effort to smooth out or iron before use.

3. Deterioration:

   • Exposure to light can weaken viscose fibers, causing the fabric to deteriorate over time. This is a significant factor when storing or wearing viscose garments under direct sunlight.
   • Viscose fibers can weaken when wet, and high temperatures or UV radiation can exacerbate this issue. Proper care should be taken to avoid exposing viscose fabrics to extreme conditions.
   • Susceptible to mildew: If stored in damp or humid conditions, viscose is prone to mildew growth.

4. Environmental Protection:

   • Since viscose is affected by water, heat, and UV light, many manufacturers incorporate chemical antioxidants and UV filters into the fibers during production. These additives help protect the fabric from degradation and enhance its durability.

Conclusion

Viscose fabric offers numerous advantages, such as breathability, color retention, and comfort, making it suitable for a wide range of applications. While it may have some drawbacks, including shrinkage, wrinkling, and susceptibility to mildew, proper care and maintenance can minimize these issues. As long as it's handled with care, viscose remains a durable and cost-effective fabric option with a luxurious feel.
