用途
- 简介
直接黑19是黑色粉末。水溶性很好，其水溶液呈绿光黑色，加入浓碱液呈绿光蓝色，加入10％硫酸颜色略显红。微溶于乙醇、丙酮。于浓硝酸中呈深棕色，于浓硫酸中呈绿光黑色，稀释后产生红光黑色沉淀。染色时遇铜离子色光微绿，遇铁离子色光略有变化。

- 直接耐晒黑 G 是主要的黑色染料品种之一。主要用于棉、黏胶纤维以及棉、黏胶纤维与蚕丝、羊毛交织、混纺织物的染色和直接印花。主要染黑色，印花则普遍采用灰及黑色，也可与棕色染料拼成各种不同深度的咖啡等色，少量用于调色光，以增加色谱。染羊毛黏胶纤维混纺织物时，可与中性黑 BRL 同浴染色，得色均匀。也可与分散染料同浴染涤黏混纺织物。上染率好，移染性稍差，染色后可用固色剂 Y、固色剂 M 处理，但色光微绿，用脲醛树脂整理可不改变色光，也能提高湿处理牢度。
