摘要： A method and system to produce treated Cellulose Filaments (CF) and CF products are provided. Feedstock comprising CF in a water solution are mixed with a debonder to produce a mixed stream. The mixed stream is filtered yielding separate filtered and filtrate streams. The filtrate stream comprises at least a portion of the debonder. The filtered stream is dried to produce treated CF. The debonder is one of an alcohol, glycol ether, ester-containing quaternary ammonium salt, amido amine quaternary ammonium salt, disubstituted amide or a mixture thereof. The filtrate stream may be recycled. The mixed stream may be washed before filtering to remove debonder. A thermoplastic polymer-treated Cellulose filament composite material is formable by associating the treated CF with a thermopolymer such as polyolefin, polyurethane (PU), polypropylene (PP), polyester (PE), polylactic acid (PLA), polyhydroxyalkanoates (PHA), polyamide (PA), and ethylene vinyl acetate (EVA) or a mixture.
