    摘要： Nonwoven fibrous webs are formed including a first group and a second group of fibers, where fibers of the first group are imparted with a degree of shrinkage that differs from a degree of shrinkage imparted to fibers in the second group. During or after bonding of the web, the web may be subjected to heat treatment causing fibers in one of the groups to shrink a greater amount in comparison to fibers in the other group, resulting in nonwoven products with desired textures and other physical characteristics.

    摘要： A nonwoven fabric having characteristics resembling woven and knitted fabrics is produced by extruding a plurality of plural component fibers, where each fiber includes first and second polymer components with the first polymer component having a degree of shrinkage when subjected to heat. A nonwoven web of the extruded fibers is formed on a web forming surface and bonded. The bonded web of fibers are post-bond treated to shrink at least the first polymer component and separate at least a portion of the second polymer component from the first polymer component utilizing any combination of heat, mechanical agitation and dissolving of fiber components. The resultant nonwoven fabric has a texture, drape and feel of woven and knitted fabrics.
