How Viscose Fiber is Manufactured

The production of viscose fiber involves transforming plant-based cellulose into a regenerated textile filament through a multi-stage chemical process.

Step 1: Extraction of Cellulose Pulp

The process begins with raw plant material, usually wood from fast-growing trees such as eucalyptus, pine, or beech.

The wood is:

• Chopped into small chips
• Chemically processed into purified cellulose pulp
• Bleached to remove impurities

This cellulose pulp forms the primary raw material for viscose production.

Step 2: Alkali Treatment

The purified cellulose pulp is treated with a 17.5% sodium hydroxide solution, which converts it into alkali cellulose.

This step breaks down the cellulose structure and prepares it for further chemical transformation.

Step 3: Xanthation Reaction

The alkali cellulose reacts with carbon disulfide (CS₂) to produce cellulose xanthate.

Cellulose xanthate is important because it can dissolve in a dilute caustic soda solution.

Step 4: Formation of Viscose Solution

The cellulose xanthate is dissolved in a dilute sodium hydroxide solution, forming a viscous orange liquid often described as a honey-like solution.

This solution is called viscose, which gives the fiber its name.

Step 5: Fiber Spinning and Regeneration

The viscose solution is extruded through spinnerets into a sulfuric acid bath.

This chemical reaction regenerates the cellulose and forms long filaments of viscose rayon fiber.

The filaments are then:

• Washed
• Bleached
• Stretched
• Cut into staple fibers if required

At this stage, the regenerated cellulose becomes a textile fiber ready for spinning and fabric manufacturing. New spinning technologies are improving the efficiency of viscose yarn production.
