Drawing, Finishing, and Cutting Once the filaments emerge from the acid bath, they undergo a series of mechanical treatments to achieve the desired properties. In response, the industry has developed more sustainable methods, most notably the Lyocell process.
Sustainable Viscose Production Techniques: The Lyocell and Other Eco-Friendly Methods
Finally, these long filaments are cut to specific lengths to create either "filament" viscose (for smooth, continuous fabrics like satin) or "staple" fiber (which is spun like cotton or wool for more textured weaves). Sulfuric Acid Spinning The viscose solution, now a thick syrup, is carefully extruded through a spinneret into a bath of dilute sulfuric acid.
This cellulose is then formed into sheets or flakes, creating a uniform base material ready for the transformative chemical processes that define how is viscose made. The Source: Cellulose Extraction The journey of viscose begins with the procurement of raw cellulose.
Adopting the Lyocell Process for Cleaner Viscose Production
While cellulose is the most abundant organic polymer on Earth, its extraction for fiber production requires precision. This viscous solution, which gives viscose rayon its name, is what makes the fiber possible and is the definitive answer to how is viscose made at a chemical level.
