  • Publication number: 20090068422
    Abstract: Disclosed herein are nonwoven fabric composites comprising layers of spunbond and meltblown nonwoven webs. Such composites are prepared by forming or assembling the layers of the composite such that there are two outer layers of spunbond fibers disposed on opposite sides of at least one inner meltblown layer. Each of the two outer layers comprises spunbond, continuous filament fibers comprising polymeric material with certain Melt Flow Rate characteristics. Further, the fibers in each of the outer layers have been partially attenuated after extrusion from a spinneret to an average of no less than about 1.8 denier per filament. The fibers within each of the spunbond layers are also predominately oriented in the machine direction of the nonwoven fabric composite. All layers of the fabric composites herein are bonded together via thermal, adhesive or ultra-sonic bonding means. Such composites exhibit substantial cross direction stretch but only minimal stretch in the machine direction.

  • Publication number: 20090068420
    Abstract: Disclosed herein are nonwoven fabric composites comprising layers of spunbond and meltblown nonwoven webs. Such composites are prepared by forming or assembling the layers of the composite such that there is at least one outer layer of spunbond fibers disposed on at least one inner meltblown layer. The at least one outer layer comprises substantially parallel stripes of spunbond, continuous filament fibers with at least two different types of stripes being used. The stripes of fibers within the spunbond layer(s) are also predominately oriented in the machine direction of the nonwoven fabric composite. All layers of the fabric composites herein are bonded together via thermal, adhesive, ultra-sonic or mechanical bonding means. Such composites can be fashioned to vary the ratio of cross direction stretch to machine direction stretch.

  • Publication number: 20090068419
    Abstract: Disclosed herein are nonwoven fabric composites comprising layers of spunbond and meltblown nonwoven webs. Such composites are prepared by forming or assembling the layers of the composite such that there are two outer layers of spunbond fibers disposed on opposite sides of eh at least one inner meltblown layer. At least one of the outer layers comprises substantially parallel lanes of spunbond, continuous filament fibers with at least two different lanes having a higher and a lower basis weight. The higher and lower basis weight lanes of fibers within the spunbond layer(s) are also predominately oriented in the machine direction of the nonwoven fabric composite. All layers of the fabric composites herein are bonded together via thermal, adhesive, ultra-sonic or mechanical bonding means. Such composites can be fashioned to vary the ratio of cross direction stretch to machine direction stretch.
