Viscose, or rayon, is a natural fiber derived from wood pulp or other plant-based materials. The production of viscose involves several steps, with cellulose playing an important role.
Here’s an explanation of what viscose is made of and how it’s produced:
Viscose is made from the following raw materials:
Pulpwood
Wood pulp, derived from various tree species such as pine, beech, eucalyptus, and spruce, is the primary raw material for viscose. These trees are usually obtained through sustainable forestry practices.
Sources of Alternative Plants
While wood pulp is the most common cellulose source for viscose, other plant-based materials such as bamboo, sugar cane, and soy can also be used. These options were chosen for their long-term viability and versatility.
The Viscose Manufacturing Process
Several key steps are involved in the production of viscose:
Pulping
The first step is to extract cellulose from the raw material of choice. Wood is mechanically pulped to separate cellulose fibers from lignin and other components. This produces wood pulp.
Treatment with Alkali
The wood pulp is then treated with a caustic soda (sodium hydroxide) solution. Alkalization is a process that breaks down cellulose into a form that can be dissolved in a solvent.
Xanthation
After alkalinization, the cellulose is reacted with carbon disulfide to form sodium cellulose xanthate. This chemical reaction produces a viscous orange solution known as “viscose.”
Ripening
The viscose solution is allowed to ripen for a set period, thickening and maturing.
Extrusion
The ripened viscose solution is extruded through tiny holes to form fine filaments. These filaments are immersed in a sulfuric acid solution to regenerate cellulose fibers.
Washing and Neutralization
The newly formed cellulose fibers are thoroughly washed and neutralized to remove any remaining chemicals and impurities.
Cutting and Drying
Depending on the application, the fibers are dried and cut into staple lengths or spun into continuous filaments.
Weaving or Knitting
The processed viscose fibers are woven or knitted into fabric or used in other ways.
Cellulose’s Role in Viscose
Cellulose is the primary component of viscose and serves as the fabric’s foundation.
It’s a natural polymer in plant cell walls that gives viscose softness, breathability, and moisture-absorbing properties.
The conversion of cellulose into a soluble form, followed by regeneration during manufacturing, is critical in producing the fine, smooth fibers that define viscose fabric.
Understanding viscose’s composition and manufacturing process sheds light on the fabric’s properties and emphasizes its eco-friendliness, as it is derived from renewable plant sources.
