发明名称 LAMINATE NON-WOVEN SHEET WITH HIGH-STRENGTH, MELT-BLOWN FIBER EXTERIOR LAYERS
摘要 A laminate non-woven sheet including a first layer, a second layer, and a middle layer. In one embodiment, the first layer consists of melt-blown fibers (and no other type of fibers), the melt-blown fibers have a strength of at least about 5 gpd or more and the first layer has a thickness. The second layer consists of melt-blown fibers (and no other type of fibers), the melt-blown fibers have a strength of about 5 gpd or more and the second layer has a thickness that is substantially the same as the thickness of the first layer. The middle layer is positioned between the first and second layers. The middle layer includes a dry-laid web of cellulose fibers. The middle layer is secured to the first and second layers by at least one of a group of bonds created by fusing fibers in the first, second, and middle layers or hydroentangling the first, second, and middle layers.
