abstract = {Two kinds of antibacterial cotton fiber (called as C_{14} and C_t) were prepared by bonding
a gemini-type quaternary ammonium compound with a hydroxyl group in their spacer chain
[1,5-bis(tetradecyl dimethyl ammonium iodide)-3- pentanol (called as DAP_{14})] and a mono-type
quaternary ammonium compound [N-tetradecyldimethyl (3-trimethoxysilylpropyl) ammonium chloride
(called as TMMP)], respectively, to the surface of cotton fiber using a coupling agent, tetraethoxysilane.
Antibacterial characteristic of C_{14} was investigated comparatively with C_t. The experimental results
indicated that C14 has higher antimicrobial activity than Ct against a broad range of microorganism,
and average net bactericidal ratio against 15 strains of gram-negative, gram-positive bacteria and
yeasts is 98.0% at 30&#176C and pH 6.0, which are 25.2 and 17.2 percentage point higher than those of C_t
at treated time of 30min and 60min, respectively. Antibacterial activity of C_{14} was hardly influenced
by environmental pH and temperature, and could not be removed from the surfaces of cotton fiber by
repeated washing with water.},
