摘要: 为了简化涤/棉混纺织物印染上色的工艺流程,节约设备和能源,设计合成能同时上染涤/棉混纺纤维的单一染料,已成为目前国际染料界争相研究的热门课题[1]。本文在前文[2]的基础上设计合成了9种颜色以红和棕红为主的丁烯二酸单酰胺染料,以硝基苯胺为重氮组分,以带有供电子取代基的芳胺为偶合组分,经偶合后所得的分散染料为母体,再用顺丁烯二酸醉酞化而制得本类丁烯二酸单酞胺染料。由于这类染料的分子同时具有分散染料的性质和活性染料的基团,可以采用一浴一步热溶法同时上染涤和棉两种性质完全不同的纤维。

Abstract: Nine new red azo dyes containing aromatic nitro group and maleic monoamide were synthesized which are capable of dyeing polyester and cotton fiber blends. Maleic monoamide substituent in the dyes makes the latter soluble in water.The dyed PET/cotton blends showed a certain grade of fastness.
