ABSTRACT:
There is provided a web which has been spun from a mixture of thermoplastic polymer and a softening additive in an amount up to about 3 weight percent, and which has been mechanically treated to increase softness. The web has a final cup crush value which is less than 50 percent of the starting cup crush value and the drop in cup crush value is greater than the sum of the treatments individually. The web may be a single layer or may be a laminate of spunbond and other materials such as meltblown and coform fabrics.
