ABSTRACT:
A blend of fibers is made of about 51 to 90% by weight of base fibers (a) selected from triangular trilobal fibers having a modification ratio ranging from 2.4 to 3.4; hollow pentagonal fibers; standard trilobal fibers having a modification ratio of at least 2.6; pointed lobe trilobal fibers having a modification ratio of at least 2.6; and mixtures thereof; and about 10 to 49% by weight of accent fibers (b) selected from standard trilobal fibers having a modification ratio ranging from 1.7 to 2.4; pointed lobe trilobal fibers having a modification ratio ranging from 2.0 to 2.9; and mixtures thereof. The fibers (a) and (b) have a denier per filament within the range represented by the area enclosed by sides A, B, C, D and E of FIG. 1. Where fibers (a) and (b) are both pointed lobe trilobal fibers with the same modification ratio and denier per filament, then fibers (a) are delustered and fibers (b) are undelustered.
