An elastic laminate capable of being rolled for storage and unwound from a roll when needed for use, includes an elastic layer of an array of continuous filament strands with meltblown deposited on the continuous filament strands, and a facing layer bonded to only one side of the elastic layer. The meltblown layer may include an elastic polyolefin-based meltblown polymer having a degree of crystallinity between about 3% and about 40%. The laminate suitably has an inter-layer peel strength of less than about 70 grams per 3 inches cross-directional width at a strain rate of 300 mm/min. Alternatively or additionally, the continuous filament strands and/or the facing layer may include an elastic polyolefin-based meltblown polymer having a degree of crystallinity between about 3% and about 40%. In certain embodiments, the elastic laminate may include an extensible facing layer bonded to an elastic or semi-elastic film layer having a basis weight of about 50 gsm or less, wherein the facing layer includes an elastic polyolefin-based polymer having a degree of crystallinity between about 3% and about 40%.

A blended composition of unsaturated block copolymer with improved thermal stability and processing behavior includes at least one unsaturated block copolymer; and a compatibilizer selected from the group consisting of (1) high melt flow rate homopolymers or copolymers; (2) styrene-ethylenepropylene-styrene (SEPS); (3) ethylene vinyl acetate (EVA); (4) styrene-butadiene-styrene (SBS), or styrene-isoprene-styrene (SIS) block copolymers; (5) single site catalyzed polyolefins, such as metallocene catalyzed and constrained geometry polyolefins; (6) amorphous poly alpha olefin homopolymer and copolymers; and (7) a combination of such.

A technique for incorporating a liquid additive into a nonwoven web is disclosed. Specifically, the liquid additive is loaded into filler particles to form a 'dry liquid concentrate', i.e., pulverulent granular solid or powder loaded with the liquid additive. The incorporation of the liquid additive into dry liquid concentrates provides a variety of benefits. For example, prior to extrusion, the dry liquid concentrates generally retain the properties of filler particles from which they are formed as the liquid remains isolated. In this manner, a higher level of the liquid additive may be compounded with a melt-extrudable base composition without adversely affecting the extrusion process. Only upon extrusion of the composition will a significant portion of the liquid additive be released to provide the desired properties to the resulting nonwoven web.

High loft, low density nonwoven webs are produced by forming substantially continuous, spunbond, crimped, bicomponent fibers of A/B bilateral morphology in an unheated fiber draw unit. The fibers are then heated and cooled in the absence of impeding forces to achieve maximum crimp in the z-direction and produce a web of lofted material. The resultant material is particularly suitable for use as an insulator. Particulates may be added to the webs if desired.

Robust homofilament fibers are meltspun from a differently shaped dual capillary spinneret design to induce differential fiber morphology to produce crimping. Crimping may further be aided by quenching and drawing of the fibers.
