ABSTRACT A drapable microporous multi-layer bonded fabric designated for medical applications, especially for use in operation rooms, which contains a microfibre centre layer of hydrophobic fibres. This is covered on both sides by optionally non-woven laminates bonded together with a bonding agent. All layers are permanently secured together by means of impressing an elastically hydrophobic bonding agent. In this manner, the bonding paste penetrates in a rod-like fashion the entire cross-section of the multi-layer construction. Also described is a process for the production of the multi-layer bonded fabric consisting of arranging a microfibre layer on top of a reinforcing material of non-woven fabric, and then applying a non-woven covering. The three-ply laminate is washed in hot water, squeezed out, and imprinted with the bonding paste. The imprinted material is then dried and is ready for use.
