Abstract: BONDED COMPOSITE NONWOVEN WEB AND PROCESS of the Invention The invention is directed to nonwoven fabrics including at least one fibrous web which preferably includes staple or natural fibers, having a bonding layer of thermoplastic material disposed primarily within a substantially discrete cross-sectional portion of the web and below at least one surface of the web. The layer of bonding material comprises a thermally fused thermoplastic web derived from a layer of thermoplastic meltblown fibers. The layer of bonding material can be an elastomeric layer or a nonelastomeric layer thus providing a fabric having elastic or non-elastic properties. The bonding layer adds strength and optionally elastic properties, to the fabric and anchors fibers of the fibrous layer in the fabric. Advantageously, the fabric of the invention is made by hydroentangled a layered web including a first fibrous layer and a layer of meltblown fibers and thermally treating the hydroentangled layered web sufficiently to fuse the thermoplastic meltblown fibers. 62560

Abstract: The invention provides elastic fabrics which exhibit low extensibility in the machine direction and have substantial elastic properties in the cross-machine direction. The fabrics of the invention include an elastic layer and a fibrous layer which are combined together. The fibrous layer is composed of a plurality of thermally activated binder fibers or filaments oriented substantially in the machine-direction of the fibrous web. The fabrics of the invention can be manufactured and processed more readily than fabrics which are elastic in both the machine direction and the cross-machine direction.

Abstract: The invention is directed to nonwoven fabrics including at least one fibrous web (12) which preferably includes staple or natural fibers, having a bonding layer (22) of thermoplastic material disposed primarily within a substantially discrete cross-sectional portion of the web and below at least one surface of the web. The layer (22) of bonding material comprises a thermally fused thermoplastic web derived from a layer of thermoplastic meltblown fibers. The layer (22) of bonding material can be an elastomeric layer or a non-elastomeric layer thus providing a fabric having elastic or non-elastic properties. The bonding layer adds strength and optionally elastic properties, to the fabric and anchors fibers of the fibrous layer in the fabric. Advantageously, the fabric of the invention is made by hydroentangling a layered web including a first fibrous layer and a layer of meltblown fibers and thermally treating the hydroentangled layered web sufficiently to fuse the thermoplastic meltblown fibers.
