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.

Abstract: A washable, sterilizable article for hospital and medical garments is disclosed. The article exhibits high resistance to the penetration of fluids, blood and viruses while exhibiting a high rate of moisture vapor transmission. The article comprises: a first layer of woven or knit fabric; a second layer of a microporous polyurethane membrane; a third layer of a woven or knit fabric; a first polyether-polyurethane adhesive joining the first and second layers together; and a second polyether-polyurethane adhesive joining the second and third layers together. The second layer has a porosity of approximately 6 billion individual pores per square inch.

Abstract: The hospital bed sheet and pillow-case material of the invention is a 2-layer fabric, incorporating a first layer of one of a fire retarding poly-cotton woven or polyester knit fabric, and a second layer of a fire retarding polyvinyl chloride film. A water-based fire retarding adhesive is included, joined between the first and second layers, for laminating them together.
