Description
Technical Field
The invention relates to the field of dyes, in particular to a high-fastness reactive red dye.
Background
The reactive dye is a main dye for dyeing cellulose fibers due to complete chromatogram, bright color, excellent performance and strong applicability. It is a dye for cellulose fibers of the highest cost performance, not only because it is one of the best choices to replace banned dyes and dyes for other types of cellulose fibers, but it also enables high levels of various fastnesses, especially wet fastnesses, to be obtained with economical dyeing processes and simple dyeing operations.
With the increasing living standard, people have higher and higher requirements on textile products, so that the requirements on various properties of the reactive dyes for dyeing textiles are more and more strict. The reactive dye not only has excellent dyeing fastness and dyeing performance, but also meets the requirement of environmental protection.

Detailed Description
The advantages of the present invention will become more apparent by describing in detail specific embodiments thereof.
Fully grinding and uniformly stirring all the components according to the mass to obtain a finished product; the disperse dye prepared in the above embodiment is subjected to performance test, and the test method is as follows:
4g of the dye mixture obtained according to examples 1 to 6 are first dissolved sufficiently with an appropriate amount of water and then taken up in a 500ml measuring flask. Sucking 10ml of dye liquor, mixing with 50ml of water, adding 4g of cotton cloth and 1.8g of sodium sulfate, raising the temperature to 60 ℃ at the heating rate of 1 ℃/minute, keeping the temperature for 30 minutes, adding 1g of sodium carbonate, keeping the temperature for dyeing for 30 minutes at 60 ℃, taking out the dyed cotton cloth, boiling and soaping for 15 minutes by using a non-ionic detergent, washing by using water and drying at about 70 ℃.
The following table shows the following detection of the application indexes of the reactive red dye of the invention:
