This invention relates to nonwoven textile with barrier properties containing a first barrier layer A with a theoretical cover coefficient TCC A, and consisting of fibres having a median fibre diameter in the layer of dAm, and a second barrier layer B with a theoretical cover coefficient TCC B, and consisting of fibres having a median fibre diameter in the layer of dBm while the first barrier layer A and the second barrier layer B are together in direct contact. The median diameters of fibres in the first and second layer have a theoretical fibre diameter coefficient x=(dBm−dAm)/dAm, where the theoretical fibre diameter coefficient x is less than or equal to 1 and where the theoretical fibre diameter coefficient x is greater than or equal to 0.25, and the sum of the theoretical cover coefficient TCC A and TCC B is greater than or equal to 50%.
