Isolation of cellulose nanofibrils from coconut waste for the production of sewing thread

Coconut waste is a by-product of commercial, industrial or agricultural activities, so that alternative uses for such waste are currently being sought. In Mexico, 66,203.22 tons of coconut waste were generated during the 2016 production cycle. Mexico City's Central Market produces 108,000 kg/year of coconut fiber waste, which is sent directly to final disposal without being submitted to any type of treatment. Therefore, the general objective of this work was to find a way to use the cellulose nanofibrils obtained from coconut fiber residues to elaborate biomaterials that may substitute synthetic fibers in textile manufacturing.
