FIELD: cellulose production.
SUBSTANCE: method of producing a spinning solution from industrial hemp involves cooking for 12 hours with mixing a mixture of a powder fraction with size of up to 250 mcm, which has undergone at least two-month maceration of a hemp stock with a degree of polymerisation from 400 to 700 in N-methylmorpholine-N-oxide with melting point of 120 °C and with water content of not more than 10% of the volume of the solvent with the addition of the antioxidant in the form of propyl gallate in concentration of 0.5% to obtain a homogeneous solution.
EFFECT: invention improves quality characteristics of spinning solution from industrial hemp due to increased volume of removed lignin during cooking of stock.
