FIELD: pulp-and-paper industry. SUBSTANCE: invention, in particular, relates to preparing concentrated cellulose triacetate spinning solutions for consequently processing them into fibers resistant to light and heat degradation and possessing elevated conductivity and resistance to repeated alternating strains. Solution contains 19-21 wt % cellulose triacetate, 0.1-0.4 wt % 1-chloro-2- formylvinylferrocene, and organic solvent: 9:1 v/v methylene chloride- ethanol mixture (the balance). Characteristics of fibers: attrition resistance 8198 cycles, resistance to double bends up to 2087, coefficient of friction with metal 0.60-0.69, conductivity (2.94-3.63) x 10<SP>-12</SP> Ohm . EFFECT: improved characteristics of fibers. 2 tbl, 4 ex
