A knitted textile fabric comprising yarn formed into interlooped stitches defining a fabric structure having a longitudinal extent and a transverse extent wherein the stitches are aligned longitudinally in a plurality of essentially parallel wales and transversely in a plurality of essentially parallel courses perpendicular to the wales, and a plurality of elongate hollow tubular segments integrated with the yarn into the fabric structure in spaced essentially parallel relation to one another, each tubular segment defining a fluid passage therein and having a rigidity sufficient to maintain a substantially constant cross-sectional dimension thereof resisting deformation such that constriction of the fluid passage is avoided.
