Embodiment 1

[0102] Embodiment 1 light fastness test

[0103] Measured according to AATCC 16E method, the measured data are listed in Table 2

[0104] Table 2

[0105]

[0106] As can be seen from Table 2, the red reactive dye composition of the present invention, compared with the dyes represented by the general formula (1), has increased and improved light fastness.

Embodiment 2

[0107] Embodiment 2 Chlorine fastness test

[0108] Measured according to ISO 105-E03 method, the measured data are listed in Table 3.

[0109] table 3

[0110]

[0111] As can be seen from Table 3, the red reactive dye composition of the present invention, compared with the dyestuffs shown in general formula (1), has greater improvement and enhancement in its chlorine fastness.

Embodiment 3

[0112] Embodiment 3 The mensuration of color fixation rate

[0113] The color fixation rate is the percentage by weight of the dyes that are finally absorbed by the fabric in the total amount of dyes. Measured as described above for the determination of color fixation rate, the values ​​are shown in Table 4.

[0114] Table 4

[0115]

[0116] As can be seen from Table 4, the fixation rate of the red reactive dye composition A, B, H of the present invention has a greater improvement than the dyes W and X shown in general formula (1).

Abstract

The invention provides a red reactive dye compound comprising one or a plurality of known red reactive dye I and red reactive dye II which are mixed together according to a certain proportion. The red reactive dye compound has bright color, wide hue range and excellent various dye fastness. Compared with the red reactive dye I and the red reactive dye II which are the components of the red reactive dye compound, the red reactive dye compound is obviously improved in the color fixation rate, the color promotion rate, the migration property, the different bath ratios during dying and the stability of different electrolyte used. More importantly, compared with the red reactive dye I, the red reactive dye compound is remarkably improved in the light fastness and the fastness to chlorine.

Description

technical field [0001] The invention relates to a reactive dye composition and its dyeing application on fiber materials, in particular to a red reactive dye composition and its dyeing application on fiber materials. Background technique [0002] The representative species widely used in current red reactive dyes is C.I. reactive red 195, whose structural formula is: [0003] [0004] This dye has a brighter hue and better color fastness, but it also has certain defects and needs to be improved. [0005] US Patent No. 5,484,899 (1996) issued by Ciba-Geigy Company discloses a red reactive dye represented by the following structural formula. It is prepared with 2,4 diaminobenzenesulfonic acid as the coupling component. Its structural formula is: [0006] [0007] The above dyes are pink in color and have good color fastness. [0008] In 2003, Everlight Company of the United States published the Chinese patent CN 1393487 (2003), further proposing an improved structure...
