ABSTRACT:
The washable, sterilizable surgical gowns and drapes of the invention are 4-layer fabrics, incorporating a first layer of woven or knit fabric, second and third layers of a continuous microporous polyurethane film, and a fourth layer of woven or knit fabric. The first and second layers are laminated together with a polyether-polyurethane adhesive to form a first composite material. The third and fourth layers are also laminated together with a polyether-polyurethane adhesive to form a second composite material. The first and second composite materials are additionally laminated together with the polyether-polyurethane adhesive to complete the quadlaminate, which exhibits a very high resistance to the penetration of fluid, blood and virus, while exhibiting a high rate of moisture vapor transmission.
