| 摘要 |
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. <IMAGE> |
