Continuous production of cost-effective and high-strength nanocellulose long filaments (NCLFs) is critical in the field of natural fiber-reinforced polymer composites (NFRPCs).Herein, we present an integrated wet-spinning system that incorporates a few previously researched filament production processes with the goal of mass fabrication of strong and tough continuous NCLFs.The spinning speed, bobbin winder speed, and NCLF drying conditions were experimentally optimized. The efficacy of the designed wet-spinning system was evaluated by its sustainability in delivering continuous NCLFs for an hour or longer without any interruptions.The two significant parameters considered for calibrating the integrated wet-spinning system are the mechanical characteristics and morphology of the fabricated NCLFs.The study has also incorporated external alignment techniques such as electric field and mechanical stretching of NCLFs to demonstrate the versatility of the designed integrated spinning system.
