(54) | Improvements in fibrous structures |
(57) 0 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. |
