Navy blue reactive dye and processing method thereof

The invention discloses navy blue reactive dye and a processing method thereof. The structural formula of the navy blue reactive dye is as shown in (I), wherein R1 is -NH2, R2 is -OH, R3 and R4 are selected from a formula shown in the description separately and independently, and R5 is chlorine or fluorine; R6 is selected from one of the following formulas: NH2CH2CH2OCH2CH2SO2W and NH2CH2CH2SO2W,X is selected from -SO2CH2CH2OSO3M or -SO2CH=CH2, R7 is selected from hydrogen atoms or C1-C4 alkane, W is selected from -CH=CH2, -CH2CH2Cl and -CH2CH2OSO3M, and M is selected from H or alkali metal.The navy blue reactive dye has the advantages of a high lifting rate, a high color-fixing rate and good dyeing fastness. 本发明公开了一种藏青色活性染料及其加工方法。该藏青色活性染料的结构式如(I)所示：式中R为-NH，R为-OH；R，R分别独立选自其中R为氯或氟，R选自下式之一：NHCHCHOCHCHSOW、NHCHCHSOW；其中X选自-SOCHCHOSOM或-SOCH＝CH，R选自氢原子或C～C的烷烃，W选自-CH＝CH、-CHCHCl、-CHCHOSOM，M选自H或碱金属。本发明藏青色活性染料具有提升率和固色率高，且具有较好的染色牢度的优点。
