A method of extracting cellulose nanofibers from bamboo fibers

摘要

The present invention relates to a method for environmentally friendly extraction of cellulose nanofibers from bamboo fibers by combining microwave liquefaction, bleaching treatment, and low-energy non-fibrillation process of bamboo fibers, comprising a first step of liquefying a bamboo-containing solution by irradiating microwaves with a microwave; A second step of bleaching the residue generated through the liquefaction using hydrogen peroxide, a third step of subjecting the bleached residue to alkali treatment and acid treatment to obtain cellulose fibers, and a low-energy blender to bleed the cellulose fibers and a fourth step of defibrillation.
