NOVELTY – Obtaining nanocellulose fibers involves selecting a raw material rich in cellulose in an feedstock and extracting fibers from the feedstock by using immersion in water. The fiber is cleaned by using a solution. The solution comprises a saponification agent, a nonionic detergent, hydrogen peroxide and sodium metasilicate. The materials are heated at 80 degrees C for 15 minutes and the fiber is whashed with warm water and then with cold water. The treated fiber is neutralized by an acidic solution of 1% acetic acid, and then enzymatic hydrolysis and sonication are performed. USE – Method of obtaining nanocellulose fibers used in textiles, cosmetic products, thermal paper and filter for capturing viruses and bacteria (claimed). ADVANTAGE – The method enables to obtain nanocellulose fibers having high-strength.
