Antimicrobial Acrylic Fiber

摘要

Fibers have been produced from a blend of poly(acrylonitrile) and poly(styrene hydantoin). The fibers were extruded from a single solvent, dimenthyl acetamide. The fibers could be chlorinated to produce halamines and thus rendered antimicrobial. The ability to regenerate the halamines (and the antimicrobial functionality) lasted through 50 home laundry washings. The chlorine adsorption was shown to be proportional to the specific surface area of the fibers, as might be expected for hydrophobic materials which can react in water only on the fiber surface.
