Abstract: A self-decontaminating fabric is manufactured from fibers such as Tencel having high surface energy and low surface roughness. Novel scouring methods eliminate substantially all contaminants from the fibers, and a novel coating process applies an anti-pathogen coating such as a halogen compound to the fabric so as to provide rapid deactivation of pathogens on contact.

The low surface roughness reduces the pickup of pathogens by the fibers. Multi-layer embodiments include an outer layer configured for maximum anti-pathogen coating concentration, and an inner layer configured for a reduced coating concentration that is compatible with skin contact.
