NOVELTY - The method for preparing agroforestry waste fiber, involves (S1) performing deforestation of agricultural and forestry wastes, removing the sediment and dust, drying until the moisture content is 20-30%, placing the agricultural and forestry waste in pre-steam tank, steaming and extruding to obtain coarse slurry, (S2) immersing coarse slurry in water, dispersing, washing with water until neutral, atmospheric refining in high-consistency disc refiner, reacting at latent temperature of 70-80 degrees C for 1-2 hours so that the fibers are relaxed and straightened, (S3) adding graphene dispersion to obtained fiber, mixing, vacuum filtering for 40-60 minutes and drying at 50-80 degrees C for 60-120 minutes to obtain graphene-containing fibers. USE - Method for preparing agroforestry waste fiber for preparation of hygiene articles or conductive paper (claimed). ADVANTAGE - The method enables preparation of agroforestry waste fiber with high yield, low cumulative value, hygienic properties and excellent antibacterial properties against Staphylococcus aureus, Escherichia coli and hemolytic Streptococcus, and does contain harmful chemicals.
