Alk. dyeing of polyester fabric can shorten the traditional dyeing process, save energy and water. It is an important direction of energy conservation and emission reduction But alk. dyeing has a higher requirement on the structural stability of dyes. With 2-amino-6-nitrobenzothiazole as diazo component and N-substituted aniline as coupling component, five disperse dyes containing different N-substituents were designed and synthesized. The dyeing properties of polyester fabric with disperse dyes under different NaOH concentrations (1-5 g/L) were tested. The relationship between dye structure and dyeing stability under basic dyeing conditions was discussed. The dyeing properties of dyes with different structures under acid and alkali conditions were compared. The results show that the hybrid dyes with Et and benzyl structure has good alkali resistance stability, acid and alkali dyeing condition does not have obvious influence on the dyeing rate of the two dyes, and the dyeing fastness is good. The experimental procedure involved many compounds, such as 6-Nitrobenzo[d]thiazol-2-amine (cas: 6285-57-0) .
6-Nitrobenzo[d]thiazol-2-amine(cas:6285-57-0Category: thiazole) has been shown to lower blood pressure in mice by inhibiting angiotensin converting enzyme and potassium channels. This drug also has a protective effect on the heart and brain from ischemia reperfusion injury.
