Beschreibung
Zusammenfassung:	Wool-like, synthetic multifilament yarns may be produced with a plurality of primary yarns and at least one secondary yarn. Generally, the primary yarn and secondary yarn may be produced from polyamides. The wool-like multifilament yarns may be produced by: (1) melt-spinning the primary yams and the secondary yarn; (2) drawing and texturizing the primary yarns and the secondary yarns; (3) entangling the texturized primary yarns and the texturized secondary yam to form the inventive yam; (4) optionally subjecting the inventive yam to heat-setting or heat annealing; and (5) winding the yam onto a package for distribution. The multifilament yarns may be used to produce floorcoverings.
