PURPOSE:To obtain the polyamide tow capable of stretch-breaking spinning in a high productivity by applying a surfactant and a specific amount of inert fine particles on the filament surface and a sufficient amount of silver- substituted antimicrobial zeolite in the filament. CONSTITUTION:The polyamide filament tow has a surfactant and inert fine particles on the surface and contains silver-substituted antimicrobial zeolite inside. The inert fine particles are preferably silica or the like. The particle pick-up is 0.01 to 1.0wt.% preferably 0.05 to 0.5wt.%, based on the fibers and enough to lower the abrasion resistance between the filaments on stretch breakage. The content of the silver-substituted zeolite depends on the amount of silver, and usually 0.01 to 20wt.%, preferably 0.1 to 2wt.%, based on the fiber. |
