Abstract
Non-woven bioactive, water and alcohol-repellent medical fabrics are described. The fabric is provided with a bioactive finish which is substantive on the fabric and is able to destroy migrating and cross-contaminating bacteria, algae and fungi. The bioactive material is 3-(trimethoxysilyl)-propyloctadecyl dimethyl ammonium chloride and is present to the extent of about 0.15 to about 1.05% on the basis of the fabric weight. A fluoropolymer provides the necessary alcohol and saline repellency. The described fabrics have numerous medical uses such as surgeon's gowns, medical drapes, isolation gowns and instrument wraps.
