Abstract

　坪量が低い不織布においても使用時において高い伸縮範囲を有し、延伸処理時に生じうる破断や強度低下を抑制するとともに、肌触りが良く、クッション性に優れた通気性の高い不織布を提供すること。 　伸縮性不織布は、縦方向と前記縦方向に直交する横方向とを有し、両面に前記縦方向に伸びる複数の帯状疎領域と複数の帯状密領域とが前記横方向に交互に連続して形成されると共に、一の面における前記帯状密領域と他の面における前記帯状密領域とが前記横方向に交互に形成される。該伸縮性不織布は、混合又は積層された伸長性繊維と伸縮性繊維とからなり、前記伸長性繊維は、前記一の面における前記帯状密領域と前記他の面における前記帯状密領域との間において、部分的に伸長された伸長性繊維を含み、前記部分的に伸長された伸長性繊維を構成する繊維の平均繊維径は、１２～２１μｍである。
