FIELD: chemistry.
SUBSTANCE: invention relates to method of spinning fibre, containing polypeptide polymer, as well as to products, including said polymer fibre. Method of fibre spinning includes draft of fibre from dope solution, containing polymer, preferably silk polypeptide which can be introduced into water solution with concentration constituting at least 0.15 mg/ml, polyacrylamide (PAA), which increases longitudinal viscosity of dope solution, and solvent. Invention makes it possible to obtain fibres, including living and non-living biological material, which could perform function of framework material for fabric engineering and growing artificial organs.
EFFECT: application of PAA in dope solution results in obtaining smooth and homogeneous fibres, non-biodegradable and long-lasting, in addition, application of very low concentrations of polymers and/or very low concentrations of improvers of PAA longitudinal viscosity facilitates spinning of fibres from dope solution.
