ABSTRACT:
Multiconstituent fibers prepared from two or more polymers, with at least one of these polymers being randomly dispersed through the fiber, in the form of domains. At least about 40 percent by weight of these domains have one length of at least 20 microns, measured in the direction along the fiber axis, and have another length, measured along the longest line dissecting the domain cross-section in a plane perpendicular to the fiber axis, of at least about 5 percent of the fiber equivalent diameter.
