Abstract (en)
There is disclosed a fluid delivery device (1, 1a) having an inlet for fluid (2) and two sheets of woven, knitted or non-woven fibres arranged as a double layer. The double layer comprises one or more fluid delivery regions (4, 4a) in which the sheets are held apart by a helical support (6, 6a) to define an internal cavity within the double layer. The device (1, 1a) is arranged such that, in use, fluid from the inlet (2, 2a) passes into the regions (4, 4a) and permeates out of the device through one or both of the sheets. Also disclosed is a fabric comprising two sheets as a double layer. The double layer comprises a plurality of regions in which the sheets are held apart by a helical support to define an internal cavity within the double layer. <IMAGE>
