    • A non-woven fabric for use as a bitumen coated and possibly bitumen impregnated carcass in a water-proofing membrane, particularly for roofs, is distinguished in that a proportion of at least 75% by weight of the fabric fibers comprise organic synthetic fibers, preferably polyester fibers, and cellulose fibers, preferably wood pulp fibers, the organic synthetic fibers constituting at least 10 and at most 90% by weight of this fiber proportion. The non-woven fabric is coated with a binder compatible with bitumen in an amount of a least 10%, preferably at least 20% of the fabric weight, the binder being selected so as to be thermally stable up to a temperature of at least 160°C and for limiting the water transport ability of at least the cellulose fibers. The invention also includes water-proofing membranes including a carcass formed by such fabric, which is coated and possibly impregnated with bitumen. The invention also includes the use of such a non-woven fabric as the carcass in such a water-proofing membrane.
    • 用于防水膜,特别是屋顶的沥青涂布和可能沥青浸渍的胎体的无纺织物的区别在于织物纤维的至少75重量%的比例包括有机合成纤维,优选地 聚酯纤维和纤维素纤维,优选木浆纤维,有机合成纤维构成该纤维比例的至少10重量%至多90重量%。 无纺织物以与织物重量的至少10%,优选至少20%的量的与沥青相容的粘合剂涂覆,粘合剂被选择为在至少160℃的温度下是热稳定的 并限制至少纤维素纤维的水输送能力。 本发明还包括防水膜,其包括由这种织物形成的胎体,其被涂覆并且可能浸渍有沥青。 本发明还包括在这种防水膜中使用这种无纺织物作为胎体。
