| 发明名称 | Spun-dyed aramid fibers | ||
| 摘要 | 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. | ||

| 主权项 | 1. Spun-dyed aramid fibers, wherein spun-dyeing was performed with a completely organic pigment having 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 only one N—C bond in the structure represented by Xa, whilst Xb is linked via the carbon atom, which is in a para relationship with the NH2-group of Xb, andR2 represents H or NH2. | ||
