Abstract: Cellulose micro- and nanofibers were produced on a base of pulp obtained as a result of thermal-mechanical and chemical pretreatment of hemp straw. Isolation of micro-and nanofibres was carried out using the enzymatic treatment with the use of a cellulolytic complex of Aspergillus niger and two-stage enzymatic and mechanical treatment. Nanofibres obtained by intense enzymatic treatment were characterized by a diameter of less than 100 nm. As a result of the two-stage enzymatic-mechanical treatment micro-and nanofibres were obtained with a diameter in the range of 25-400 nm and a length of several hundred nanometers to several micrometers.
