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 partially-oriented yarn. The multifilament yarns made from these filaments are useful to make articles with subdued luster and low glitter.

La présente invention concerne des filaments polymères à section multilobée. Ladite section peut être caractérisée par un facteur de filament supérieur ou égal à 2,0 environ et par un rapport de pointe supérieur à 0,2 environ. Ces filaments peuvent être utilisés comme fil brut de filage, comme fil d'alimentation orienté selon le filage ou comme fil partiellement orienté. Les fils multifilaments produits à partir desdits filaments sont utilisés dans la fabrication d'articles peu brillants à lustre atténué.
