摘要： A spun nonwoven fabric contains monofilaments and bicomponent filaments, the spun nonwoven fabric having, over its cross section, different quantities of the bicomponent filaments. The bicomponent filaments contain at least two outward-facing segments made of a binding component. The proportions of bicomponent filaments over the cross sectional planes of the spun nonwoven fabric can be in a range of approximately 1% to 100% by weight. The cross sectional planes of the nonwoven fabric containing the different proportions of bicomponent filaments transition into one another without detectable phase boundaries. The apparatus for manufacturing the nonwoven fabric contains at least one, and may contain up to forty or more, spinneret devices, such as rectangular spinneret plates or round spinneret disks. The spinneret devices may be arranged in rows or in staggered arrangement above a linearly moving collector belt. Spinning orifices on the spinneret devices are respectively dedicated to producing a monofilament or a bicomponent filament from a melt and, viewed in the direction of motion of the collector belt, are arranged with respect to one another so as to correspond in their totality to the cross sectional structure of different filament types in the nonwoven fabric.

摘要： A spunbond nonwoven fabric is provided which is formed from continuous multiple component filaments which include a polyester component and a polyethylene component. The polyethylene component is a blend of high density polyethylene and a first linear low density polyethylene. The spunbond filaments are preferably formed in a sheath-core configuration with the polyester component in the core and the polyethylene component in the sheath. Composite sheets are provided which include the multiple component spunbond layer and a meltblown layer, wherein the meltblown fibers include a second linear low density polyethylene. The linear low density polyethylenes are preferably formed by polymerization of ethylene with an alpha-olefin co-monomer, where the same co-monomer is used in each of the first and second linear low density polyethylenes.

摘要： Sound attenuating laminates, and methods of making the same, are provided. Heat is applied to a surface of a non-woven, fibrous layer of material to form a stratum of melted fibers having a density greater than that of the remainder of the fibrous layer. The density of the melted fibers is effective in attenuating noise traversing the fibrous layer of material. Upholstery material, such as carpeting, is attached to the surface of the heated fibrous layer. The fibrous layer and upholstery material are then subjected to compressive molding pressure to obtain a desired shape. The compressive molding pressure may further tune the sound attenuating properties of the fibrous layer by selectively changing the densities of portions of the fibrous layer.

摘要： The present invention relates to a method for improving the abrasion resistance of a spun-bonded nonwoven without substantially adversely affecting its hand or drape characteristics, by incorporating low melt binder fibers into the web during the laydown phase of the spun-bonded nonwoven production process. More specifically, improved abrasion resistance is achieved by intimately blending continuous binder fibers with the primary extruded fibers in a spun-bonded nonwoven web. Also encompassed within this invention is a spun-bonded nonwoven fabric having improved abrasion resistance and comprised of primary extruded fiber and low melt binder fiber such that the binder fiber comprises between about 1 and about 50 weight percent on weight of the spun-bonded nonwoven fabric.

摘要： A nonwoven web made from a polymeric fiber blend comprising at least one elastomeric polyolefin and at least one nonelastomeric polyolefin useful as the elastic base sheet for a nonwoven laminate is disclosed. Preferably, the polymeric blend will comprise a nonelastomeric resin in the range of from about 10 to about 90 percent by weight, and an elastomeric resin of from about 90 to about 10 percent by weight. The elastomeric polyolefin will have a density of less than about 0.885 g/cm3 and the nonelastomeric polyolefin will have a density of at least about 0.890 g/cm3. In one particular embodiment, the polymeric blend may comprise about 50 percent to about 90 percent by weight of a narrow molecular weight distribution polyethylene and about 50 percent to about 10 percent by weight of a nonelastomeric polyolefin such as a linear low density polyethylene.
