Purpose. Determination of consumer properties of cellulose, obtained from fiber, stems and ostriches of non-narcotic monocute hemp for recommending it in production at pulp and paper industry enterprises. Methodology. Experimental studies of consumer properties of cellulose from fiber, stems, and ostriches of non-narcotic homogeneous hemp were performed using current standard techniques and measuring instruments. Findings. The functional, aesthetic properties and reliability of the consumption of the obtained cellulose on the basis of non-narcotic homogeneous hemp of crushed stalks and fibers, namely: air permeability, 1m2 mass, destructive effort (dry, wet), rigidity, absolute resistance to corrosion, tightness, are investigated. It is established that the qualitative characteristics of cellulose on the basis of crushed stalks of non-narcotic homogeneous hemp have the highest value of air permeability, in comparison with cellulose obtained from hemp fiber, respectively: 1475 l/m2 s and 320 l/m2 s. The destructive effort of fiber pulp is higher at 4H. The absolute resistance to squeezing cellulose from the fiber is higher by 50kPa compared with hemp straw pulp. A comparative analysis of physical and mechanical properties of cellulose from stalks and fibers is carried out in accordance with the normative requirements of GOST 9094-89 "Offset paper. Specifications" shows that the fiber content of 1m2 and the destructive effort of cellulose derived from non-narcotic monocute hemp fibers corresponds to the highest grade, whereas from the cut stems, non-narcotic monogeous hemp - the first brand and in its quality exceeds cellulose derived from wood. Originality. The regularities of the influence of the components of non-narcotic homogeneous hemp (fibers, stalks, and ostriches) on the chemical composition and physical and mechanical properties of cellulose are established. The practical value. A new composition on the basis of cellulose from fibers and crushed stems of non-narcotic monogastric hemp with improved functional properties has been developed, which ensures the reliability of the consumption of the obtained cellulose by increasing its mechanical strength. The industrial testing of consumer characteristics of cellulose, obtained from the bonfire, stalks and fibers of non-narcotic monocute hemp on the "Tsyurupinsk Paper Company" Ltd., Tsyurupinsk, Kherson region, was carried out. Such technical cellulose from nonnarcotic monogamous hemp can be recommended as a raw material for the production of offset printing paper in accordance with GOST 9094-89
