Beschreibung
Zusammenfassung:	Spun-dyed aramid fibers, wherein spun-dyeing was performed with a completely organic pigment, characterized in that the pigment exhibits the chemical structure of formula (I), wherein independently from one another Ri represents a substituent of formula Xa or a substituent of formula Xb (II), (III) wherein Xa is linked via the group NH on the left hand side of the triazine ring, whilst Xb is linked via the carbon atom, which is in a para relationship with the NH2 - group, and R2 represents H or NH2. The spun-dyed aramid fibers exhibit constant colouristic properties and wash proof properties. La présente invention concerne des fibres aramides teintes dans la masse, la teinture dans la masse étant réalisée avec un pigment complètement organique, caractérisé en ce que le pigment présente la structure chimique de formule (I). Dans la formule, indépendamment les uns des autres, Ri représente un substituant de formule Xa ou un substituant de formule Xb (II), (III), Xa est lié par le biais du groupe NH sur le côté gauche du noyau triazine, tandis que Xb est lié par le biais de l'atome carbone, qui est en relation para avec le groupe NH2, et R2 représente H ou NH2. Les fibres aramides teintes dans la masse présentent des propriétés coloristiques constantes et des propriétés de résistance au lavage.
