ABSTRACT:
Multifilament polyester yarn, of multilobal filaments having specified cross-sectional characteristics, is false-twist textured into yarn which provides fabrics having improved visual aesthetics. The examples illustrate that freedom from objectionable glitter is obtained with 6 to 10-lobed filaments, having essentially symmetric lobes of equal length equispaced around a central axis of the filament, when the modification ratio is from 1.17 to 1.85, and the denier per filament is between 3.8 and a maximum value which is a function of the modification ratio and the number of lobes.
