preparation example Construction

[0065] The present invention further provides a method for preparing the red disperse dye according to the second aspect, which specifically includes: in the presence of auxiliary materials, granulating the mixture of each dye component with a pulverizer; or The components are respectively granulated with a pulverizer in the presence of auxiliary materials, and then mixed.

[0066] Specifically, in some specific embodiments of the present invention, the various dye compound components of the red disperse dye composition are mixed according to a specific ratio, and are mixed with a sand mill or a grinder in the presence of auxiliary agents and water. In other specific embodiments of the present invention, the individual components in the red disperse dye composition can also be pulverized with a sand mill or a grinder in the presence of auxiliary agents and water. Machine for granulation treatment, after granulation treatment, mix according to specific ratio.

[0067] In some ...

Embodiment 1

[0078] With 36 grams of formula (I) compound, 17 grams of formula (II) compound, 16 grams of formula (III) compound and 31 grams of additives (12 grams of diffusion agent NNO and 19 grams of dispersant MF), add 150 grams of water to mix After mixing, use a grinder to grind and disperse and spray dry to obtain red disperse dye products with excellent fastness properties.

[0079]

Embodiment 2

[0081] With 26 gram formula (I) compound, 23 gram formula (II) compound, 19 gram formula (III) compound, 10 gram (IV) compound and the auxiliary agent of 22 gram (the diffusion agent NNO of 5 gram and the dispersion agent of 17 gram MF), after adding 150 grams of water and blending, use a grinder to grind and disperse and spray dry to obtain the excellent red disperse dye products of each fastness performance.

Abstract

The invention provides a red disperse dye composition, a red disperse dye and a preparation method and application thereof. The red disperse dye comprises the following components: component A as shown in formula (I): component B as shown in formula (II): and, component C as shown in formula (III): the present invention The described red disperse dye composition has excellent lifting power and various color fastnesses. Specifically, the red disperse dye composition of the present invention can obtain better lifting power and higher color fastness than traditional dyes on acetate fabrics, especially the smoke fastness and color fastness on light-colored fabrics. Good light fastness, no catalytic fading.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a red disperse dye composition, a red disperse dye and a preparation method and application thereof. Background technique [0002] Acetate fibers, especially diacetate fibers, have good air permeability and antistatic properties, and the fabrics are bright in color and soft to the touch, and have good market prospects at home and abroad. Due to the fiber characteristics of diacetate fiber itself, disperse dyes with low molecular weight and similar dyeing rate have become the most suitable dyes for printing and dyeing diacetate fibers, among which red disperse dyes are essential basic dyes for all manufacturers. Traditional red disperse dyes, such as C.I. Disperse Red 356, etc., have the disadvantages of low dyeing performance and various color fastnesses when printing and dyeing diacetate fiber fabrics, which cannot meet the market demand well. Therefore, in view of the above-mentioned probl...
