    • A composite material (4) for use as, or to provide, a disposable product, such as a nappy/diaper, said composite material being flushable and biodegradable and comprising an outer soluble layer (2) supporting a disintegratable and dispersable liquid absorbent layer (5), and a liquid impervious barrier (3) interposed between the soluble layer (2) and the absorbent layer (5), with the soluble layer and liquid impervious barrier being in synergistic relationship, whereby the composite material maintains its integrity during normal use but loses its integrity in response to the action of water when disposed of in a water flushing system. When the composite material is used, for example as a nappy/diaper, a skin-contacting cover which is also biodegradable covers the absorbent layer (5).
    • 一种用于或提供诸如尿布/尿布的一次性产品的复合材料(4),所述复合材料是可冲洗的和可生物降解的,并且包括支撑可分解和分散的液体吸收层的外部可溶层(2) 5)和介于可溶层(2)和吸收层(5)之间的液体不可渗透屏障(3),其中可溶层和液体不可渗透屏障是协同关系的,由此复合材料在正常使用期间保持其完整性 但是当在水冲洗系统中处理时响应于水的作用而失去其完整性。 当使用复合材料时,例如尿布/尿布,也可生物降解的皮肤接触覆盖物覆盖吸收层(5)。
