This semi-synthetic fiber is derived from cellulose, primarily sourced from wood pulp, which is then chemically transformed into a material that mimics the luxurious feel of silk. Understanding how is viscose made reveals a complex process that bridges sustainable botany and intensive chemical engineering, making it a cornerstone of the modern textile industry.
The Industrial Production of Viscose Fiber: From Cellulose to Finished Filament
While technically a subset of viscose production, Lyocell uses a non-toxic amine oxide solvent in a closed-loop system that recycles nearly all chemicals. Subsequently, the alkalized cellulose is pressed, shredded, and aged to reduce its molecular weight.
Drawing, Finishing, and Cutting Once the filaments emerge from the acid bath, they undergo a series of mechanical treatments to achieve the desired properties. Viscose, often referred to as rayon, occupies a unique space in the world of textiles.
The Industrial Production of Viscose Fiber: From Cellulose to Finished Filaments
The pulp is mechanically or chemically treated to remove lignin and hemicellulose, leaving behind nearly pure cellulose. This opens the molecular structure of the cellulose.
