Title:

STRETCH COMPOSITE FABRIC AND STRETCH POROUS POLYTETRAFLUOROETHYLENE FILM

Document Type and Number:

WIPO Patent Application WO/2007/145283

Kind Code:

A1

Abstract:

A stretch composite fabric which comprises a stretch porous polytetrafluoroethylene film which has been burned and a stretch cloth laminated thereto while maintaining a flat state. The 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 elongated in the lengthwise direction under a load of 300 g and then released from the stress, the recovery from elongation (R) which is given by the following equation is preferably 70% or more. R=(L2-L3)/(L2-L1)Œ100 (In the equation, L1, L2, and L3 indicate the lengths of the composite fabric before loading, under loading, and after load removal, respectively.)
