Asymmetric multilayered non woven fabric which also provides fluid absorption properties. By being multilayered, the features of isolating against moisture in one direction and the permeability of fluids in the opposite direction are increased. The non woven fabric comprises: one or more layers of hydrophobic filaments which comprise a polyolefin; one or more layers of hydrophilic elements which comprise a mixture of a polyolefin and an additive or combination of additives; where the layer at one of the ends of the non woven fabric is hydrophobic and the layer at the other end of the non woven fabric is hydrophilic, and where the aforementioned additive or combination of additives provides the polyolefin with hydrophilic properties as well as fluid absorption properties.
