Abstract
(EN)
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)×100 (In the equation, L1, L2, and L3 indicate the lengths of the composite fabric before loading, under loading, and after load removal, respectively.)
(FR)
Tissu composite extensible, lequel comprend un film de polytétrafluoroéthylène poreux extensible qui a été brûlé et une étoffe extensible stratifiée sur celui-ci tout en les maintenant à plat. Le tissu a une contrainte à la traction à 10 % d'allongement, telle que mesurée dans au moins une direction, inférieure ou égale à 1,8 N/15 mm. Lorsqu'on étire une éprouvette de 5 cm de large du tissu composite extensible dans la direction de la longueur sous une charge de 300 g et qu'on relâche ensuite la contrainte, la récupération après l'allongement (R), laquelle est donnée par l'équation suivante, est de préférence supérieure ou égale à 70 %. R=(L2-L3)/(L2-L1)×100 (Dans l'équation, L1, L2 et L3 représentent les longueurs du tissu composite avant application de la charge, sous la charge et après avoir enlevé la charge, respectivement.)
(JA)
 伸縮性複合生地は、焼成された延伸多孔質ポリテトラフルオロエチレンフィルムと伸縮性布帛とが平坦状態を維持したままで積層されており、10%伸張時の引張応力が少なくとも1方向で1.8N/15mm以下になっている。前記伸縮性複合生地は、幅5cmの試験片を荷重300gで長さ方向に伸張した後、応力を除去したときの伸びの回復率Rを下記式で表したとき、この回復率Rが好ましくは70%以上になっている。   R=(L2-L3)/(L2-L1)×100  (式中、L1は荷重を負荷する前、L2は荷重を負荷しているとき、L3は荷重を除去した後の複合生地の長さを示す)
