Abstract:
A stretch composite fabric comprises a sintered expanded porous polytetrafluoroethylene film and a stretch cloth laminated to each other while maintaining a flat state. The stretch composite fabric has a tensile stress at 10% elongation, as measured in at least one direction, of 1.8 N/15 mm or less. When a 5 cm-width test piece of the stretch composite fabric is stretched in a length direction under a load of 300 g and then released from the stress, an elongation recovery R of the stretch composite fabric, which is given by the following equation, is preferably 70% or more. R=(L2−L3)/(L2−L1)×100 (In the equation, L1, L2, and L3 represent the lengths of the composite fabric before the load is applied, when the load is applied, and after the load is removed, respectively.)
