preparation example Construction

[0092] The preparation method of the red reactive dye composition of the present invention comprises mixing the above-mentioned dye I and dye II according to a prescribed weight ratio. Various conventional methods can be used for mixing, such as mechanical mixing methods. When mixed, Dye I and Dye II may be present in powder form, or in granular form. For example, the mixing step can be carried out in suitable mills such as ball mills or pin mills as well as in kneaders or mixers.

[0093] The red reactive dye composition of the present invention can be applied to the fiber material and fixed to the fiber by various methods known in the art, for example, it can be dyed by exhaust dyeing method or pad dyeing method.

[0094] The red reactive dye composition of the present invention is suitable for the dyeing application of cotton fiber and wool fiber.

Embodiment 1-9 and comparative example 10-15

[0114] According to the type of dye shown in Table 1 and the amount thereof, various dye components are evenly mixed by conventional methods in the art to prepare the various red reactive dye compositions of this clear embodiment and the various red reactive dyes of the reference ratio.

[0115] "%" in Table 1 means % by weight, based on the total weight of the red dye composition.

Abstract

The invention provides a red reactive dye composition and application thereof. The dye composition consists of one or more dyes expressed by the right general formula (I) and one or more dyes expressed by the general formula (II) which are mixed according to a certain proportion. Compared with the dyes expressed by the general formula (I), the fixation rate, promotion rate and compatibility of the red reactive dye composition are remarkably improved. Surprisingly, the red reactive dye composition has quite excellent various dye fastnesses.

Description

technical field [0001] The invention relates to a red reactive dye composition and its dyeing application on cellulose fiber and wool fiber. Background technique [0002] One of the constituent dyestuffs of the red reactive dye composition that the present invention relates to is C.I. active red 223# and similar structure dyestuff thereof, and this class dyestuff is the well-known reactive dyestuff containing amide group, and its general structure is: [0003] [0004] General formula (I) [0005] The color of this kind of dye is yellowish red, and it has good color fastness to washing, color fastness to rubbing and light fastness. However, its improvement rate, color fixation rate, color fastness to perspiration and color fastness to perspiration and light need to be further improved. [0006] Japan's Sumitomo Corporation patent JP4033965 has introduced C.I. Reactive Red 223# and C.I. Reactive Red 195# blending in a certain proportion, thereby improving the dyeing perf...
