A textile (10) comprising first and second conductive layers (12a, 12b); at least one porous layer (14) positioned between first and second conductive layers (12a, 12b), the pores of said porous layer (14) extending in a direction substantially perpendicular to said conductive layers (12a, 12b); the conductive layers (12a, 12b) being connected to an electric signal generator (15) such that, in use, a voltage can be applied across said porous layer (14) to effect directional flow of liquid across said textile (10), and a voltage can also be applied along at least one of the conductive layers (12a, 12b) to effect heating of said textile (10).
