A monoazo dye for polyester fiber represented by formula (I)
and having a crystal modification characterized by an X-ray diffraction spectrum (CuKa) showing a very strong peak at an angle of diffraction (2θ) of about 14,2°, a strong peak at about 24,5°, and four weak peaks at about 16,9°, 23,6°, 25,3°, and 26,8°. The monoazo dye exhibits excellent dispersibility to effect level dyeing even under high temperature and severe conditions and provides a dyed material excellent in light fastness and rubbing fastness, as well as wet fastness after post-finish.
一种用于聚酯纤维的单偶氮染料,由式(I)表示,其晶体改性的特征是 X 射线衍射谱(CuKa)在衍射角(2θ)约为 14.2°处显示一个非常强的峰,在约 24.5°处显示一个强峰,在约 16.9°、23.6°、25.3°和 26.8°处显示四个弱峰。 该单偶氮染料即使在高温和苛刻的条件下也能表现出极佳的分散性以达到匀染效果,并提供耐光牢度、耐摩擦牢度以及后整理后的耐湿牢度极佳的染色材料。
