                            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.
