Non-woven fabrics are rendered repellent to water, saline, body fluids and solvents according to the disclosed process that applied bioactive finish that becomes substantive on the fabric and serves to destroy migrating and cross-contaminating bacteria, algae and fungi. The finish serves to lower the amount of microbial contamination while providing a barrier to liquid penetration. Fabrics so treated are useful as surgeon\s gowns, medical drapes, isolation gowns, instrument wraps and the like.
