The influence of the basic technological parameters of traditional and organosolvent methods of cooking cellulose from stalks and fibers of non-wood plant material for its quality were investigated. The effect of alkaline extraction in quality microcrystalline cellulose from hemp fibers was determinated. The process of obtaining organosolvent hemp pulp was investigated. Depending quality parameters of microcrystalline cellulose to major technological factors was established. The technology of obtaining microcrystalline cellulose from hemp and flax fibers was developed.
