A fiber-fiber composite is disclosed herein comprising majority fibers and minority fibers, the minority fibers having a softening point lower than said majority fibers such that when the admixture of majority fibers and minority fibers are wet laid to form a paper-like structure and subjected to a pressure and a temperature above the softening point of said minority fibers, said majority fibers and minority fibers form said composite having a mean pore diameter equal to or less than about 1 mum with a porosity of greater than about 35%, and a wet strength of greater than about 0.013 kg/mm.
