ABSTRACT:
An integral fibrous structure has a plurality of continuous polymeric filaments, individual continuous filaments extending from one side of the structure to the opposite side of the structure. The portions of the continuous filaments on one side of the structure are of a first polymeric composition and the portions of the same continuous filaments on the opposite side of the structure are of a second polymeric composition different from the first polymeric composition. The structure is built up by a continuous filament forming process where fibers are attracted to a surface (11) by electrostatic potential, the composition of the fibers being varied during the production.
