摘要：
Structures containing a fiber mat inserted into a high modulus scrim of minimum basis weight 35 gsm. The structures have reduced tensile elongation at 50 N per 5 cm fabric strip in MD under ISO 9073-3standard norm. The structure has a basis weight of at least 9 ounces per square yard (305 grams per square meter ). The structure also has heat resistance of at least 150 to 190C, preferably over 200 up to 260C to for service under typical hot flue gas filtration conditions. Filter bags made from these structures provide a controlled dimensional stability over their entire filter life time. In addition such stable structures are suitable for lamination with fragile membranes especially e-PTFE membranes where minimum amount of mechanical damage to the membrane occurs.
摘要（中）：
包含插入到最小基重35gsm的高模量稀松布中的纤维垫的结构。 根据ISO 9073-3标准规范，该结构在MD下每5cm织物条带的拉伸伸长率降低了50N。 该结构的基重至少为9盎司每平方码（305克/平方米）。 该结构还具有至少150至190℃，优选超过200至260℃的耐热性以用于在典型的热烟道气过滤条件下的使用。 由这些结构制成的过滤袋在整个过滤器使用寿命期间提供受控的尺寸稳定性。 此外，这种稳定的结构适用于与易碎膜特别是e-PTFE膜层压，其中发生最小量的机械损伤。
