Graft of Bis-QAC to Cotton Fiber and its Antibacterial Characteristics

Abstract:

The bis-type quaternary ammonium salts (bis-QAC) with hydroxyl group in their molecules, 4,5-Bis (alkyl dimethyl ammonium bromide)-1-pentanol were immobilized on cotton fiber to prepare an antibacterial cotton fibers (called as Ws) by using a coupling agent, tetramethoxysilane. The antibacterial characteristics of Ws were investigated. 4,5-Bis (alkyl dimethyl ammonium bromide)-1-pentanol chemically bonded to the surface of cotton 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.
