BIOCIDAL POLYAMIDES AND METHODS

摘要

Biocidal polyamide materials such as deodorant and/or biocidal Nylon3 polyamide fibers, fabrics and surfaces and biocidal Aramid (such as Kevlar3 and Nomex3) fibers, fabrics and surfaces, and methods of preparation. Heterocyclic N-halamine precursor moieties are covalently linked to the polyamide material. The fabrics and/or fibers thereafter obtain antimicrobial activity after washing with a halogenated solution to convert the heterocyclic precursor moieties into heterocyclic N-halamines. The antimicrobial activity against pathogenic microorganism can be repeatedly regenerated by washings with a halogenated solution.
