An effective two-stage method for obtaining both biologically activated fibres with antibacterial and anaesthetic activity and biologically activated complex fibres -insulin as an artificial store of insulin has been developed. The first stage involves the formation of reactive functional groups by chemical modification, followed by the second stage where the fibres are modified with chemotherapeutic agent solutions. This paper presents the results of obtaining biologically activated fibres with antibacterial and anaesthetic activity as well as an artificial store of insulin in the form of complex ion-exchanged fibre-insulin. The level of immobilisation of the drug in the antibacterial fibre amounts to 140 mg of gentamicin sulphate per 1 g of fibres, in the anaesthetic fibre 180 mg of procaine hydrochloride per 1 g of fibres, and in the fibrous store of insulin 800 mg of insulin per 1 g of fibres.
