ABSTRACT:
A method for the manufacture of disposable operation textiles. In the method at least on first layer of a non-woven fibre fabric material is fastened onto at least one second similar layer so that the principal fibre orientations of the layers become at least approximately perpendicular to each other. Said second layer is coated with a heat-sealable layer of synthetic material so that said layer in molten state and under tension is allowed to flow onto the web of fibre fabric. Then the combination is cooled whereby an internal prestress is produced and fixed in the coating of synthetic material. Said second layer is applied onto the first layer such that the layer of synthetic material comes against said first layer and the layers are fastened to each other by heat compression so that heat sealing occurs.
