Abstract
Dyed, absorbent bioactive wettable fabrics are prepared by mixing together a wettable hydrophilic organosilicone polymer, a tinctorial amount of a compatible direct dye and a bioactive silyl quanternary amine. The mixture is applied to a non-woven cellulose-containing substrate then heated to dye the coated substrate, fix the dye and couple the microbiocide and hydrophilic coupling agent to the substrate. Fabric so produced is useful as an absorbent surgical drape or dressing to isolate a surgical incision site while providing an absorbent antimicrobial field to destroy migrating and cross-contaminating bacteria, algae and fungi.
