摘要

A method for producing nanosilver on a large scale, a method of manufacturing nanosilver-adsorbed fiber, and an antibacterial fiber manufactured thereby. The nanosilver having a size of 5 nm or less can be generated on a large scale by controlling a minutely electronic current between the two Ag electrodes in a water electrolysis system, while a voltage of 10,000˜300,000 is applied to two Ag electrodes. The nanosilver-adsorbed fiber is manufactured by applying the aqueous solution containing nanosilver to the surface of the synthetic fibers; adsorbing the nanosilver onto the synthetic fibers using a process selected from the group consisting of thermal fixation, high frequency radiation, bubbling, and combinations thereof; and conducting post-finishing at 160 to 200° C.
