Abstract

In the cellulose industry, the viscose process is still occupying the leading position, although this process generates several environmentally hazardous byproducts. Here we report a novel method for the production of cellulose multifilament from cellulose carbamate (CC) on a pilot scale. In this method, CC was first prepared efficiently by microwave heating; it was then dissolved in NaOH/ZnO aqueous solutions through a freezing-thawing process. Wet spinning of the CC solution was performed on a pilot-scale machine. The cellulose multifilament displayed a dense circular microstructure and excellent physicochemical properties. The tensile strength and elongation at break of the multifilament in dry state were 2.58 cN/dtex and 12.1%, respectively. Moreover, the process could utilize most of the conventional equipment for the viscose method, which could have a great impact on the current cellulose industries.
