Abstract

PURPOSE:To keep antibacterial property and prevent coloring of fibers by subjecting the fibers containing a silver series inorganic antibacterial agent to contact with a treating liquid containing a coloring inhibitor consisting of a specific component. CONSTITUTION:For example, antibacterial fibers spun from a formulated concentrate containing a silver series antibacterial agent are subjected to contact with a treating liquid, obtained by adding a coloring inhibitor consisting of an azole compound having non mercapto group into a treating solution (e.g. a solution containing an oil solution for spinning, an after oil agent, a coding oil, a dying solution or a finishing agent) except a compound of the formula (R<1> is H or low alkyl; R<2> is H or alkali metal) which is used from a spinning process till a higher degree of processing, hence preventing coloring caused by silver ion to obtain antibacterial fibers having high goods value. As the coloring inhibitor, benzothiazole, benzimidazole, etc., can preferably be cited as examples.

2. Description of the Related Art Generally, it has long been known that silver ions have antibacterial properties. For example, it is widely used as a disinfectant or bactericide in the form of an aqueous solution of silver nitrate. Various methods have been proposed as methods for applying the antibacterial property of silver ions to fibers. For example, an antibacterial agent in which zeolite solid particles carry silver ions, an antibacterial agent in which phosphate-based or condensed phosphates carry silver ions, and an antibacterial agent in which calcined hydroapatite carries silver ions. It is a method of imparting antibacterial properties by kneading an inorganic antibacterial agent such as

The mechanism of preventing coloration of these azole compounds is not clear, but probably the amide group (NH) in the azole compound forms a chelate compound with a minute amount of dissolved silver ion to form a chelate compound and the activity of the silver ion. It is presumed that the coloring agent is prevented by preventing oxidative deterioration of the oil agent and, conversely, preventing silver ions from being oxidized to form silver oxide (AgO) by killing.

By containing the azole compound in the treatment liquid and bringing it into contact with the antibacterial fiber, the azole compound adheres to the surface of the fiber, so that coloring can be efficiently prevented. On the other hand, when this azole compound is kneaded into the fiber and used, the ratio of the anti-coloring agent on the surface of the fiber becomes extremely small, so that the anti-coloring effect cannot be exhibited. Further, since the melting temperature of the anti-coloring agent is low, it is almost volatilized at a normal spinning temperature, and the effect cannot be exhibited.
