Abstract: Systems and methods are disclosed for producing multi-layer meltblown mats. The method includes depositing first meltblown fibers onto a first moving surface such as a conveyor belt to form a first layer of meltblown fibers, and depositing second meltblown fibers onto a second moving surface such as a conveyor belt to form a second layer of meltblown fibers. The first and second layers of meltblown fibers are fed through opposed rollers to form combined meltblown layers comprising the first layer of meltblown fibers and the second layer of meltblown fibers. The combined meltblown layers are bonded together to produce a bonded multi-layer meltblown sheet. The bonded multi-layer meltblown sheet has a first outer exposed surface formed by contact of the first layer of meltblown fibers with the first moving surface, and a second outer exposed surface formed by contact of the second layer of meltblown fibers with the second moving surface.

Abstract: Provided is a composite sheet material including a nonwoven fabric having an outer exterior surface comprising a plurality of discreet, spaced-apart projections extending outwardly from the exterior surface. Collectively, the spaced-apart projections define a three-dimensional topography characterized by the plurality of spaced-apart projections and valleys disposed therebetween. The composite sheet material is particularly useful as a wiper instrument.

Abstract: 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.

Abstract: A degradable composite non-woven fabric being a layered structure with an upper surface layer, an intermediate fiber layer, and a lower surface layer in sequence. The upper and lower surface layers are mainly composed of degradable melt-blown fibers. The intermediate fiber layer is mainly composed of degradable water-absorbing fibers, wherein the weight of fibers of the intermediate layer accounts for more than 65% of the total weight of the composite non-woven fabric, and there are fiber interwoven regions between the upper surface layer and the intermediate fiber layer, as well as between the lower surface layer and the intermediate fiber layer.
