Problems solved by technology
However, its enhancement, color fixing rate, and fastness to chlorinated water need to be further improved. It is mainly used for dyeing light colors, which is difficult to meet the current printing and dyeing needs, thus limiting its wide use.
[0005] Introduced in Japan's Sumitomo Corporation patent JP4033965, C.I reactive red 195# and C.I reactive red 223# are blended in a certain proportion, to improve the light fastness and perspiration color fastness of C.I reactive red 195#, but this dye composition The color fixation rate and improvement still need to be further improved

[0061] Examples 1-12 and Comparative Examples 1-3: Dye Compositions
[0062] The components and contents of the dye compositions used in the examples of the present invention and the comparative examples, as well as the single component dye (the latter as a reference dye), are listed in Table 1. The percentages of each dye component are based on the total weight of the dye composition.
[0063] The dye composition of the present invention is prepared by mixing in a mechanical grinding manner according to the following weight ratios.

The invention provides a red active dye composition which comprises one or a plurality of dye(s) selected from general formula (I) and one or a plurality of dye(s) selected from general formula (II) which are mixed according to a certain proportion. The red dye composition has beautiful color as well as good dyeing property and dye fastness. The color fastness to light, the perspiration light fastness and the like of the red active dye composition are superior to those of the common red dye. Compared with single component dye, the color fixing rate, the promotion property and fastness to chlorinated water of the active dye composition are obviously improved and enhanced.
Description
technical field [0001] The invention relates to a red reactive dye composition and its dyeing application on fiber materials. Background technique [0002] Red reactive dyes and their compositions have always been one of the hot spots in the research and development of the dye industry. [0003] As the quality requirements for dyed products such as cellulose fibers and their fabrics are getting higher and higher, people's requirements for various performances of reactive dyes used for dyeing are also increasingly demanding. Reactive dyes are required not only to have excellent dyeing properties Fastness, and must have good dyeing performance. [0004] One of the constituent dyestuffs of a kind of red reactive dye composition that the present invention relates to is C.I active red 223# or its similar structure dyestuff, and this class dyestuff is the well-known reactive dyestuff containing amide group, and its structural formula is as shown in general formula (I) stated.
