Abstract

An integral fibrous structure has a plurality of continuous polymeric filaments, individual filaments extending from one side of the structure to the opposite side of the structure. The portions of the filaments on one side of the structure are of a first polymeric composition and the portions of the 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 fibre forming process where fibres are attracted to a surface (11) by electrostatic potential, the compounds of the fibres being varied during production.
