The instant invention provides nonwoven fabrics and staple or binder fibers prepared from an ethylene-based polymer having a Comonomer Distribution Constant in the range of from greater than from 100 to 400, a vinyl unsaturation of less than 0.1 vinyls per one thousand carbon atoms present in the backbone of the ethylene-based polymer composition; a zero shear viscosity ratio (ZSVR) in the range from 1 to less than 2; a density in the range of 0.930 to 0.970 g/cm3, a melt index (12) in the range of from 15 to 30 or from 10 to 50 g/10 minutes, a molecular weight distribution (Mw/Mn) in the range of from 2 to 3.5, and a molecular weight distribution (Mz/Mw) in the range of from less than 2.

Disclosed is a laminate comprising at least one polyolefin elastic film layer and at least one substrate layer; the polyolefin elastic film having the following properties: (1) an average integrated enthalpy sum of no greater than 17 J/g, preferably between about 5-17 J/g, according to the Thermal Analysis Method defined herein; (2) an average integrated enthalpy ratio of from 0.6 to 300, preferably 0.8 to 300, still preferably 1.0 to 300, according to the Thermal Analysis Method defined herein; and (3) an unload stress at 75% strain of above 0.8 MPa according to the Hysteresis Test defined herein; and wherein the laminate has a normalized load force/normalized unload force ratio at 75% strain of 1 to 2.6 according to the Hysteresis Test defined herein.

Compositions of biobased polymer blends of polymers and a polyhydroxyalkanoate copolymer are described. In certain embodiments, the copolymer is a multiphase copolymer blend having one phase a glass transition temperature of about 5 C. to about 50 C. Methods of making the compositions of the invention are also described. Also articles, films and laminates made from the compositions are described.

A multi-denier nonwoven composite fabric having a nested structure is hydraulically treated by particular process parameters to improve softness and tactile feel.

A nonwoven substrate comprising a polyolefin and an engineering thermoplastic polymer. The engineering thermoplastic polymer may be present in the nonwoven substrate at a level of between about 1% and about 20% by weight of the nonwoven substrate. The layer of fibers is free of a compatibilizer.

A nonwoven laminate having a SMS structure is hydraulically treated by particular process parameters to improve softness and tactile feel. The nonwoven laminate may also be imparted with one or more regular aperture patterns by additional hydraulic treatment processes, where the initial hydraulic treatment provides for improved aperture definition.

Invention relates to a multilayer article comprising successively: a non-woven layer of fibers (3) comprising at least 50% by weight of at least one biodegradable polymer melting point of which is below 220 C.; a layer of food-safe adhesive (2); a cellulose-fiber based support (1).

A melt spinnable fiber is provided that comprises a first component comprising a thermoplastic polymer, and a second component comprising thermoplastic starch where the second component is not encompassed by another component or components or if encompassed by another component or components then the second component encompasses a hollow core. A particular use of such a fiber is for removal of the second component in the presence of a solvent in order to produce fibers with desired properties. An agent may be present in the second component for controlling the rate of removal of the second component thereby allowing for physical manipulation of the fiber prior to complete removal of the component. The invention is also directed to nonwoven webs and disposable articles comprising the fibers.

A hydroentangled integrated composite nonwoven material, includes a mixture of randomized continuous filaments, splittable shortcut staple fibers, and optionally non-splittable staple fibers. The splittable fibers should be 3-16 mm long bicomponent fibers. Preferably there should be no thermal bonding points between the filaments. The nonwoven material has improved textile feeling and reduced two-sidedness. The continuous filaments should preferably be spunlaid filaments. Some of the staple fibers can be colored. A process of producing such a nonwoven material is disclosed.

Thermoplastic bicomponent binder fiber can be combined with other media, fibers and other filtration components to form a thermally bonded filtration media. The filtration media can be used in filter units, such as breather caps. Such filter units can be placed in the stream of a mobile fluid and can remove a particulate and/or fluid mist load from the mobile stream. The unique combination of media fiber, bicomponent binder fiber and other filtration additives and components provide a filtration media having unique properties in filtration applications.
