Beschreibung
Zusammenfassung:	Porous, permeable particles of meta-aramid can be chlorinated or brominated to produce antimicrobial and detoxifying particles for use in applications such as, but not limited to, nonwoven webs, paper, textiles, absorbent articles, healthcare products, paints, filter materials, powder coatings, clear coatings, molded plastic articles, binders for fibrous materials, and the like. The particles can be charged with halogen before or after incorporation into the application medium. The particles can contain blends of meta-aramid with other polymers such as, but not limited to, cellulose, cellulose acetate, polyurethane, and the like. The particles will be effective at inactivation of pathogenic and odor-causing microorganisms and toxic chemical agents. The particles, which contain N-halamine units, have unexpected resistance to ultraviolet light degradation.
