摘要： Filter media comprising non-woven fiber webs having one or more advantageous physical properties are generally described. In some embodiments, a filter media and/or non-woven fiber web described herein comprises a combination of fibers that results in enhanced physical properties. For example, the non-woven fiber web may comprise a combination of fiber types that is advantageous, such as a combination comprising fibrillated fibers, glass fibers, and/or binder fibers. In some cases, the filter media and/or non-woven fiber web comprising the combination of fibers may be formed into undulations (e.g., by a creping and/or microcreping process) to further enhance the physical properties of the filter media and/or non-woven fiber.

摘要： Filter media comprising non-woven fiber webs having high performance are generally described. For instance, in some embodiments, a non-woven fiber web described herein has a relatively high value of gamma and/or a relatively high ratio of dust holding capacity to basis weight. As another example, in some embodiments, a non-woven fiber web described herein is capable of being loaded with dust relatively uniformly throughout its depth. This latter property may assist with increasing the gamma and/or the ratio of dust holding capacity to basis weight.
