Synthesis of Grafted Copolymer of Wool Keratin by Polymethacrylic Acid and the Properties of Modified Bactericide Fibres

Abstract

The possibility of getting bactericide wool fibres by means of modification by graft polymerization of methacrylic acid are examined. Through their carboxylic groups some bioactive preparations have been fixed in the fibre. K2S2O8 - Na2S2O3, (1:2.5 mol/mol) has been used to initiate the reaction of grafting, and by means of kinetics the optimum conditions of the reaction (70 °C; pH = 2.0) and the basic kinetic parameters of the process were determined. The basic physical-mechanical properties of modified fibres after the process of grafting were determined. It was found out, that grafting degree higher than 20 - 25 % causes damages of fibres. Modified wool fibres with Rifamicin SV and Klocsacylin as antibiotics have remarcable bactericidic properties towards some kinds of pathogenic microorganisms.
