What is Viscose Fabric: Pros, Uses, Care

 
What is Viscose Fabric
 

Viscose fabric is a type of semi-synthetic fiber produced from natural sources such as wood pulp combined with chemical processing. It falls between natural fibers like cotton and synthetic fibers like polyester in terms of characteristics. This fabric is known for its softness, breathability, excellent drape, and versatility, making it a popular choice in the apparel, home textiles, and industrial sectors.

 
Production Process of Viscose
 

• The process begins with the extraction of cellulose from wood pulp or other plant materials.
• The cellulose is chemically treated with sodium hydroxide to produce alkali cellulose.
• This alkali cellulose is then combined with carbon disulfide to form cellulose xanthate.
• The cellulose xanthate is dissolved in a dilute solution and then forced through a spinneret to form fibers.
• The fibers undergo a regeneration process by exposure to an acid bath, which converts them back into cellulose in a fibrous form.

Care and Maintenance of Viscose Fabric
 

• It is advisable to follow specific care instructions, such as gentle hand washing or dry cleaning to maintain the fabric’s appearance.
• Avoid prolonged exposure to moisture to prevent deterioration of the fiber strength.
• Iron on a low setting when necessary to combat wrinkles, as viscose tends to crease easily.

Preparation

• Examine the care label on your viscose garment for any specific washing instructions. Manufacturers often provide guidance on water temperature, detergent type, and recommended washing methods.
• Separate your viscose items from heavy or abrasive fabrics to prevent damage during washing.
• Prepare a clean area and gather all necessary supplies including mild detergent, a basin or sink, and clean, cool water.

Hand Washing Process

• Fill a basin or sink with cool or lukewarm water. Avoid very hot water as it can weaken the fibers and cause shrinkage.
• Add a small amount of mild detergent designed for delicate fabrics. Mix gently until the detergent is evenly distributed.
• Submerge the viscose garment, gently agitating the water with your hands to allow the detergent to work through the fabric. Avoid excessive rubbing or scrubbing to prevent distortion.
• Let the garment soak for about five minutes to loosen any dirt or oils without damaging the fibers.
• After soaking, gently swirl the garment in the water for even cleaning, then rinse thoroughly with cool water until no detergent residue remains.

Wringing and Drying

• Avoid twisting or wringing the fabric, as this can lead to stretching or damage. Instead, lift the garment from the water and gently press out the excess liquid.
• If needed, lay the garment flat on a clean, absorbent towel. Roll the towel and the garment together, applying light pressure to remove additional water without causing creases.
• Place the garment on a drying rack or lay it flat on a clean surface away from direct sunlight and heat sources. This helps maintain the shape and integrity of the fabric.

Ironing and Post-Wash Care

• Viscose tends to wrinkle easily; if ironing is necessary, use a low heat setting. Place a thin pressing cloth between the iron and the garment to prevent burn marks.
• Always iron the fabric slightly damp, as this can help smooth out wrinkles more effectively without applying too much heat.
• For garments with embellishments or prints, refer back to the care instructions to ensure that ironing won’t cause any damage or fading.

 
Understanding Viscose and Its Origins
 

• What is Viscose? – Viscose is a type of rayon fiber created from regenerated cellulose. It blends natural components (like wood pulp or cotton linters) with chemical processes to yield a versatile textile material.
• Sourcing Cellulose – The primary raw material for viscose is cellulose derived from renewable sources such as hardwood trees, bamboo, and cotton waste. These sources offer a sustainable basis, although the actual sustainability depends on responsible forestry and processing practices.
• Chemical Transformation – The natural cellulose undergoes a series of chemical treatments. It is first dissolved by reacting it with chemicals such as sodium hydroxide and carbon disulfide, converting it into a soluble cellulose xanthate before regeneration into fibers.

 
Comprehensive Viscose Production Process
 

• Preparation and Pulping – Wood, bamboo, or cotton linters are processed into a fine pulp. This pulp is purified to remove impurities and ensure consistency before further processing.
• Xanthation – The purified cellulose is transformed into cellulose xanthate by reacting with sodium hydroxide and carbon disulfide, which makes it soluble in a particular chemical solution.
• Dissolution – After xanthation, the cellulose xanthate is dissolved in a dilute solution. This step creates a viscous liquid solution ready for fiber formation.
• Spinning – The liquid cellulose solution is extruded through spinnerets into an acid bath. The acid regenerates the cellulose, converting it into solid fibers. The process parameters such as spinneret design and acid concentration are carefully regulated to achieve desired fiber qualities.
• Post-Treatment – The newly formed fibers are washed, bleached, and sometimes further treated with chemical finishes to enhance softness, durability, and dye affinity.

 
Where Viscose is Grown: Global Production Hubs and Their Environment
 

• Geographical Concentration – Major viscose production centers are found in countries with an abundant supply of raw materials, advanced chemical processing industries, and established textile markets. These include parts of Asia (notably China and India), Southeast Asia, and some European countries.
• Infrastructure and Technology – Production facilities are typically located in zones with access to both raw materials and skilled chemical manufacturing infrastructure. These areas benefit from robust supply chains and technological expertise necessary for the complex chemical processes.
• Environmental Considerations – Due to the use of chemicals such as carbon disulfide, strict environmental regulations and sustainable practices are essential. Modern production methods emphasize reducing chemical emissions, using closed-loop processes, and ensuring safe waste disposal. Certification schemes and monitoring bodies work toward reducing the environmental footprint.
