A profiled cross-section three-dimensional woven fabric having a plurality of woven, mutually intersecting filaments woven in longitudinal, transverse and vertical planes, with transverse planes of different widths and vertical planes of different height within a cross-section of the woven fabric perpendicular to the longitudinal woven filament planes. The woven filament in the transverse planes moving upward or downward while transversely reciprocating over a width which changes with the width of the woven filaments in each longitudinal woven plane and being disposed between vertically adjacent planes of longitudinal filaments. The woven filaments in the vertical planes moving longitudinally to the height of disposition of the longitudinal and transverse filaments in a plane perpendicular to the transverse filaments and being continuously disposed between longitudinally adjacent layers of transverse filaments, clamping the transverse and longitudinal filaments to unite them together. An even number of transverse filaments are inserted into at least one each transversely elongated transverse space surrounded by vertically adjacent vertical filaments with one or a plurality of the transverse filaments inserted into each loop formed by adjacent vertical filaments above the longitudinal filaments in the uppermost layer and below the longitudinal filaments in the lowermost layer.
