A nonwoven fabric produced by a method comprising the following steps:
a) providing a first plurality of polymeric filaments having a first denier of between 0.5 and 15 and a second plurality of polymeric filaments having a second denier of between 0.5 and 15, wherein said second denier is at least 1.5 times greater than said first denier, at least one of said first and second plurality of polymeric filaments including a polymer selected from the group consisting of nylon, polypropylene and polyethylene;
b) directing the first and second plurality of filaments onto a collection surface to form a web;
c) mixing the first and second plurality of polymeric filaments to form a nonwoven fabric comprising at least 25% round and multilobal filaments of the second denier, the second plurality of polymeric filaments comprising at least 5% of the round polymeric filaments of the second denier; and
d) forming a multiplicity of discrete bond sites in the fabric to bond together said filaments.
