Lenzing Closes European Lyocell Plants Squeezing Textile Fiber Supply
Textile buyers must shift sourcing of premium lyocell fibers to consolidated hubs as 135,000 tons of European capacity exits.
Man-Made Cellulosic Fibers
Chemical Classification
Regenerated pulp polymers processed through chemical extraction and wet or dry-jet wet spinning yield bio-based regenerated textile fibers. Products classified under man-made cellulosic fibers include viscose, modal, lyocell and cupro, which bridge the property gap between natural cotton and synthetic polyester. Manufactured from renewable wood sources, these materials offer high moisture absorption, smooth draping characteristics and biodegradability in natural environments.
Processing Mechanism
Dissolving wood pulp dissolves in chemical solvents such as sodium hydroxide and carbon disulfide for traditional viscose, or N-methylmorpholine N-oxide for closed-loop lyocell production. The viscose process requires chemical recovery systems to capture sulfur emissions and recycle chemical bath inputs. Lyocell production utilizes closed-loop solvent recovery that recycles over ninety-nine percent of the organic solvent back into the process stream.
Extrusion through spinnerets into coagulation baths forms solid filaments that undergo washing, stretching, crimping and drying. Fiber cross-sections and physical strength attributes are controlled by adjusting solvent concentration, spin bath temperature and draw ratios during extrusion.
Feedstock Dependency
Dissolving pulp sourcing relies on sustainable forestry management practices certified by international forestry governance bodies. Price fluctuations in wood pulp directly influence manufacturing costs and final fiber market pricing. Synthetic fiber competition and agricultural land competition alter pulp supply allocations between paper and textile industries.
