MELT SPUN YARNS HAVING HIGH LUSTRE

The invention provides a profiled polyamide yarn having a yarn weight of from 5 to 300 dtex a filament weight of from 0.5-7 dtex and a non-circular profiled filament cross-section, wherein the polyamide comprises from 0.01 to 3% by weight of a non-white pigment melt dispersed therein. The yarns have...

Beschreibung
Zusammenfassung:	The invention provides a profiled polyamide yarn having a yarn weight of from 5 to 300 dtex a filament weight of from 0.5-7 dtex and a non-circular profiled filament cross-section, wherein the polyamide comprises from 0.01 to 3% by weight of a non-white pigment melt dispersed therein. The yarns have a high, metallic lustre due to the combined effect of profiling and the non-white pigment. The invention also provides textile fabrics comprising the yarns, and garments comprising the said fabrics. The invention also provides methods of making the inventive yarns by spinning a polyamide melt having the non-white pigment dispersed therein. L'invention concerne un film de polyamide profilé présentant un poids de 5 à 300 dtex et un poids de filament de 0,5-7 dtex, ainsi qu'une section transversale de filament profilé non circulaire. Le polyamide comprend de 0,01 à 3 % en poids d'un pigment non blanc fondu, dispersé. Les fils présentent une forte brillance métallique résultant de l'effet combiné du profilage et de la présence du pigment non blanc. L'invention concerne également des tissus textiles comprenant de tels fils, ainsi que des vêtements comprenant lesdits tissus. Elle concerne en outre des procédés de fabrication des fils selon l'invention par filage d'un polyamide en fusion dans lequel est dispersé le pigment non blanc.
