摘要： The invention is directed to composite elastic nonwoven fabrics and processes for producing the same. The fabric includes a layer of inelastic continuous or staple fibers formed from a blend of polyethylene and polypropylene laminated to an elastic layer. Preferably, the composition of the fibers ranges between 5 to 50 percent by weight of polypropylene with the balance made up of polyethylene. The nonelastic fibers are capable of being highly elongated upon mechanical stretching without adversely impacting fiber tie down. Accordingly, a smooth, strong, coherent fabric is obtained, which is especially well suited for incorporation into disposable absorbent articles such as diapers, training pants, incontinence briefs and feminine hygiene products.

摘要： A spunbond nonwoven fabric useful as a topsheet is produced from polypropylene filaments including a high level of reclaimed polypropylene, while maintaining a product quality, including superior formation, comparable to that obtained when using 100 percent virgin polymer. The spunbond nonwoven fabric is made with multicomponent filaments having at least two different polymer components occupying different areas within the filament cross section, and wherein one of the polymer components comprises reclaimed polypropylene recovered from previously spun polypropylene fiber or webs comprised of previously spun polypropylene fiber. In a specific embodiment, the filaments are sheath-core bicomponent filaments and the reclaimed polypropylene is present in the core component. The core of the bicomponent filament can be comprised of up to 100% reclaimed polypropylene.

摘要： A nonwoven material having a laminated construction and including a first layer of nonwoven fibers defining a first surface of the material; a second layer of nonwoven fibers defining the opposite surface of the material; and a third layer of nonwoven fibers located between the first and second layers. The layers are bonded together to form a laminate. At least one of the nonwoven layers comprises a nonwoven web of meltblown fibers. Additionally, one or more of the layers has been rendered permanently hydrophilic by forming the nonwoven web from meltspun fibers of a normally hydrophobic polymer having a hydrophilic melt additive incorporated therein.
