Title
(JA) 複合シート材料
Abstract
(JA)

第1の側と第2の側とを有する透湿性をもった一体となっている重合体フィルム、および
透湿性をもった粉末接合された不織布層から成る第1の不織布層を具備し、該第1の不織布層は繊維の不織布ウエッブから成り、該不織布ウエッブの繊維の95重量%より多くが該重合体フィルムと相容性をもち、該第1の不織布層は該フィルムを該第1の不織布層の上に押出し被覆することによって重合体フィルムの第1の側に接着させられて折、該フィルムの第2の側に接着された随時使用される第2の透湿性をもった不織布層を含んでいることを特徴とする透湿性をもち液体に対しては実質的に不透過性である複合シート材料。
