Abstract
An antibacterial polyamide filament which comprises a polyamide resin containing 0.1 to 5.0 mass % of fine zinc oxide particles and exhibits a color difference caused by the treatment with an alkaline solution of 2.5 or less; and a method for producing the antibacterial polyamide filament which comprises adjusting the moisture content of a polyamide resin chip to 0.05 to 2.0 mass %, followed by melt spinning. Preferably, the antibacterial polyamide filament has a bacteriostatic activity after 50 washings of 2.2 or more, which filament can be produced by melt-spinning the polyamide resin to melt spinning and solidifying the resin at a position 400 mm or less from the face of a spinning nozzle.
