Abstract:
Spun-dyed aramid fibers, wherein spun-dyeing was performed with a completely organic pigment exhibiting the chemical structure of formula (I): wherein, independently from one another, R1 represents a substituent of formula Xa or a substituent of formula Xb: wherein Xa is linked via the group NH having two bonds in the structure represented by Xa, while Xb is linked via the carbon atom, which is in a para relationship with the NH2-group of Xb; and R2 represents H or NH2. The spun-dyed aramid fibers exhibit constant coloristic properties and wash proof properties.
