Composite reactive dark blue dye and application thereof

The invention discloses a composite reactive dark blue dye and application thereof. The composite reactive dark blue dye comprises three specific components that are shown as the formula (I), the formula (II) and the formula (III), wherein in the components, M is H, Na, K or Li independently. The invention discloses the application of the composite reactive dark blue dye in dyeing of a chinlon mixed fabric and in a brocade-cotton mixed fabric product. The composite reactive dark blue dye can be used for dyeing the chinlon mixed fabric independently without the cooperation of other types of dyes; in addition, the composite reactive dark blue dye can be used for dyeing brocade and cotton in a same bath simultaneously, the coloring is synchronous, dyeing steps are simplified, and the using amounts of salt and alkali are reduced. 本发明公开了种复合活性深蓝染料及其应用，复合活性深蓝染料包括三种特定的组分，式(Ⅰ)、式(Ⅱ)和式(Ⅲ)，其中，各组分中M独立地为H、Na、K或Li；以及其在对锦纶交织织物染色中和锦棉交织织物制品中的应用；本发明的复合活性深蓝染料能够单独对锦棉交织织物进行染色，无需其它类型染料配合染色，且可在同浴中对锦棉进行同时染色，上色同步性致，精简了染色步骤，且降低了染色用盐、碱的
