ABSTRACT:
Acrylic fiber with persistent antifungal properties can be prepared by extruding a dope which comprises an acrylic polymer in solution and an antifungal agent through a die into a coagulating bath. The antifungal agent is preferably a neutral organic compound of low solubility in water, for example tolnaftate. The antifungal agent is preferably dispersed in the fiber in the form of fine particles.
