Immobilization on wool fiber and antibacterial characteristic of novel bis-type quaternary ammonium salts
The two kinds of bis-type quaternary ammonium salts (QACs) with hydroxyl group in their molecules, 1, 5-bis (tetradecyl dimethyl ammonium iodide)-3-pentanol A-14 and 4, 5-bis (dodecyl dimethyl ammonium bromide)-l-pentanol B-12 were immobilized on wool fiber, respectively, by using a coupling agent. Antibacterial wool fibers (called as W<,A-14> and W<B-12>, respectively) were obtained and their antibacterial characteristics were investigated. A-14 and B-12 chemically bonded to the surface of wool fiber exhibited antimicrobial activity against a broad range of microorganism. Their antibacterial activity was not easily influenced by environmental pH and temperature, and could not be removed from the surface of wool by repeated washing.
