Abstract
Polyamide yarn provided with a built-in antimicrobial capacity characterized by the adhesive on the fiber surface of an antimicrobial agent comprising an organosilicon quaternary ammonium salt and a surfactant comprising an alkyl-, aryl-, alkenyl-, or arylsulfonate salt, optionally with the presence of a level-dyeing promoter.
Claims7
In a filament spinning process in which a polymer is melt-spun from a spinneret and subsequently drawn and heated, the improvement comprising spinning a melt spun continuous polyamide undrawn filament, the filament having a molecular structure that has not been completely stabilized, applying to the surface of the filament, fixing an adhering thereto effective amounts of both an organosilicon quaternary ammonium salt and a surfactant selected from the group consisting of alkyl, aryl, and aralkylsulfonate salts, the quaternary ammonium salt and the surfactant being applied to the filament before the filament is drawn and heated.
