Abstract
This invention provides polymer filaments having a multilobal cross-section. The cross-section can have a filament factor of about 2.0 or greater and a tip ratio of greater than about 0.2. The filaments may be used as-spun as a spin-oriented feed yarn or as a direct use yarn. The multifilament yarns made from these filaments are useful to make articles with subdued luster and low glitter.
