Introduction
Viscose filament yarns (VFY) have gained immense popularity in the textile
industry due to their silk-like feel, high absorbency, and eco-friendly nature.
Derived from natural cellulose, viscose filament yarns offer a sustainable
alternative to synthetic fibers. This article explores the properties,
manufacturing process, applications, advantages, and market trends of VFY.
What is Viscose Filament Yarn?
Viscose filament yarn is a type of regenerated cellulosic fiber made from wood
pulp. It is known for its softness, sheen, and excellent drape, making it a
preferred choice for high-end textiles. VFY is available in different grades,
including bright, dull, and semi-dull variants, catering to diverse fabric needs.
Manufacturing Process of Viscose Filament Yarn
The production of viscose filament yarn involves several key stages:
1. Raw Material Selection: The process begins with high-quality wood pulp,
primarily sourced from fast-growing trees such as eucalyptus, bamboo,
and pine.
2. Pulp Processing: The wood pulp is treated with chemicals to extract
cellulose, which is then converted into alkali cellulose.
3. Xanthation: The alkali cellulose reacts with carbon disulfide, forming
cellulose xanthate.
4. Spinning Solution Preparation: The cellulose xanthate is dissolved in a
diluted sodium hydroxide solution to create a viscous liquid known as
viscose.
5. Filtration and Aging: The viscose solution is filtered to remove impurities
and aged to enhance its properties.
6. Extrusion and Coagulation: The solution is forced through spinnerets into
an acid bath, where it solidifies into fine filaments.
7. Stretching and Drying: The filaments are stretched to improve tensile
strength and then dried to remove excess moisture.
8. Winding and Packaging: The final yarn is wound onto spools and prepared
for distribution.
Properties of Viscose Filament Yarn
Viscose filament yarn possesses unique characteristics that set it apart from
other fibers:
•
Silk-like Appearance: VFY has a smooth and lustrous texture, making it a
cost-effective alternative to silk.
•
High Absorbency: The yarn absorbs moisture efficiently, enhancing
comfort and breathability.
•
Softness and Drape: Its excellent drape makes it ideal for flowing
garments and luxurious fabrics.
•
Biodegradability: Unlike synthetic fibers, VFY decomposes naturally,
reducing environmental impact.
•
Dyeability: It takes dyes well, resulting in vibrant and long-lasting colors.
