摘要： A composite filter for removing particulates entrained in a gas has stack of at least two non-pre-bonded tiers of filter material which are bonded together to form a unitary stratified structure. The tiers can include thermally bindable components such as bicomponent or monocomponent polymer fibers, or adhesively bindable components, such as pulp fibers, especially fluff pulp, split film fibers, mixed electrostatically charged fibers and staple fibers. In addition to vacuum cleaner bags, the novel filter composite can be utilized in applications such as heating ventilation and air conditioning (HVAC) systems, vehicle cabin air filters, high efficiency (so-called “HEPA”) and clean room filters, emission control bag house filters, respirators, surgical face masks and the like.

摘要： The invention refers to a composite filter for filtering a stream of ambient air including at least one non-prebonded upstream tier and one non-prebonded downstream tier, wherein the ratio of absolute pore volume of upstream tier to downstream tier RAPV>2, and the absolute projected fiber coverage of upstream tier and of downstream tier APFC>95%. Further, the invention refers to a method of making such a composite filter including the steps of (a) laying down a filtration material onto a support to form the upstream non-prebonded tier, (b) depositing onto the upstream tier the downstream non-prebonded tier, and (c) bonding the tiers to form a composite filter having a unitary stratified structure.

摘要： A vacuum filter bag is constructed of layers which include a high air permeability multipurpose layer positioned upstream in the direction of air flow of a second filtration layer. The second filtration layer can be a wet-laid filter paper, a dry-laid filter paper or a spunbond nonwoven. The multipurpose layer can be made of high bulk meltblown nonwoven, dry-laid or wet-laid high dust holding capacity paper spunblown modular or microdenier spunbond. The high dust capacity papers are characterized by greater thickness and higher air permeability than is normally used in traditional filter layers of vacuum cleaner bag structures. These characteristics allow the high capacity papers to filter large dirt particles and to capture within their pores large amounts of dust particles. This protects the downstream second filtration layer from shock loading and enables the composite structure to pass air at high rate at low pressure differential for much longer than conventional vacuum cleaner bags. A method of filtering gas through such a filter is also disclosed.
摘要翻译：真空过滤袋由层构成，其包括位于第二过滤层的空气流动方向上游的高透气性多功能层。第二过滤层可以是湿法成网的滤纸，干法成网的滤纸或纺粘无纺布。多用途层可以由高体积熔喷无纺布，干法成网或湿法成网的高吸尘量纸喷吹模块或微滴纺粘合剂制成。高吸尘纸的特点是比真空吸尘器袋结构的传统过滤层通常使用的厚度更大，透气性更高。这些特性允许大容量纸张过滤大颗粒，并在其孔内捕获大量的灰尘颗粒。这样可以保护下游的第二过滤层不受冲击负荷影响，使得复合结构能够以低压差的高速通过空气比传统的真空吸尘器袋长得多。还公开了通过这种过滤器过滤气体的方法。

摘要： A disposable vacuum cleaner filter bag is constructed of layers which include a filtration grade meltblown fleece layer having a basis weight of about 10-50 g/m2 and air permeability of about 100-1000 L/(m2×s) and a coarse filter layer in which the coarse filter layer is placed upstream of the filtration grade meltblown fleece layer. The coarse filter layer can include either wet-laid high dust capacity paper, dry-laid high dust capacity paper, high bulk meltblown nonwoven, Spunblown (Modular) nonwoven or microdenier spunbond nonwoven. Juxtaposition of the layers causes the coarse filter layer to capture large dirt particles and permits the filtration grade meltblown fleece layer to capture much of the remaining dust particles. The novel bag exhibits high air permeability and low pressure drop at high dust loading. A method of filtering gas through such a filter is also disclosed.
