摘要

(US9126390) 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.)

主权利要求

(US9126390) The invention claimed is: 5.  A method for producing a stretch composite fabric comprising: laminating a sintered expanded porous polytetrafluoroethylene film to a stretch cloth in a non-stretched state;   stretching the resulting laminate in a uniaxial direction while preventing the occurrence of necking; and   shrinking the laminate by removing the stretching force. 1. A method for producing a stretch composite fabric comprising: laminating a sintered expanded porous polytetrafluoroethylene film to a stretch cloth in a non-stretched state to form a laminate, said expanded porous polytetrafluoroethylene film being in a flat state;   stretching the laminate in a planar direction so as to increase the area of the laminate to 1.4 times or more; and   shrinking the laminate by removing the stretching force,   wherein said flat state of said sintered expanded porous polytetrafluoroethylene film is measured by a ratio (LT/LW) of a true length LT of the sintered expanded porous polytetrafluoroethylene film to an apparent length LW of the film, and   wherein said ratio is 1.2 or less. 2. The method for producing a stretch composite fabric according to claim 1, wherein the stretching and shrinking of the laminate are performed at 220 deg. C. or lower. 3. The method for producing a stretch composite fabric according to claim 1, wherein the shrinking of the laminate is performed at a temperature of 50 deg. C. or higher. 4. The method for producing a stretch composite fabric according to claim 1, wherein said expanded porous polytetrafluoroethylene film possesses a stretch property in the absence of an elastomeric layer. 6. A method for producing a stretch composite fabric comprising: laminating a sintered expanded porous polytetrafluoroethylene film to a stretch cloth in a non-stretched state to form a laminate, said expanded porous polytetrafluoroethylene film being in a flat state;   stretching the laminate in biaxial directions; and   shrinking the laminate by removing the stretching force.
