Abstract

Thermally divisible multicomponent fibers (4) having at least a first component including an elastomeric polymer (6) and at least a second component including a non-elastomeric polymer (8). The multicomponent fibers are useful in the manufacture of nonwoven structures, and in particular nonwoven structures used as synthetic suede and filtration media.
