Viscose Fiber: A Synthetic Alternative to Silk and Wool
Viscose is a type of synthetic fibre made from wood pulp. It is created through a process called cellulose xanthation, which involves treating wood pulp with a chemical solution to break down the cellulose molecules and then reforming them into a new fiber. The resulting fibers are soft, smooth, and have a silky texture, making them suitable for use in clothing, upholstery, and other textile applications.
Viscose is also known as rayon, and it has been around since the early 20th century. It was first developed in France by a team of scientists led by Count Hilaire de Chardonnet, who were looking for a way to create a synthetic fiber that could mimic the softness and drape of silk. The name "viscose" comes from the Latin word "viscum," which means "mucilage," a type of sticky substance.
Viscose fibers are made by dissolving wood pulp in a chemical solution, then forcing the resulting liquid through a spinneret to create the fibers. The fibers are then washed, dried, and woven or knitted into fabric. Viscose can be blended with other fibers, such as cotton or polyester, to create fabrics with specific properties. For example, adding cotton to viscose can make it more breathable and absorbent, while adding polyester can make it stronger and more durable.
Viscose has several advantages over natural fibers like silk and wool. It is less expensive to produce, and it can be made in a wide range of colors and textures. It is also soft and comfortable to wear, and it drapes well. However, viscose can be prone to shrinkage and creasing, and it may not hold up as well as natural fibers over time.
In recent years, there has been some controversy over the use of viscose in fashion due to concerns about its environmental impact. The production of viscose requires large amounts of wood pulp, which can lead to deforestation and habitat destruction. Additionally, the chemicals used in the manufacturing process can be harmful to workers and the environment. Some fashion brands have started using more sustainable alternatives to viscose, such as bamboo or recycled polyester.
