preparation example Construction

[0077] The preparation method of the red acid dye composition of the present invention comprises: mixing the above-mentioned dye I, dye II and dye III in a prescribed weight ratio, and mixing can use various conventional methods, such as mechanical mixing methods. Mixed formula, dye I, dye II and dye III can exist in powder form, or granular form. For example, the mixing step can be carried out in mills such as ball mills or pin mills as well as in kneaders or mixers using the art.

[0078] The red acid dye composition of the present invention can be used for dyeing nylon fibers, wool fibers and cellulose fibers.

Embodiment 1-10 and comparative example 1-2

[0080] The types of dyes and their dosages shown in Table 1 below were used to uniformly mix various dye components according to conventional methods in the art to prepare various red acid dye compositions of Examples 1-10 of the present invention.

[0081] "%" in Table 1 means % by weight, based on the total weight of the dye composition.

Abstract

The invention discloses a red acidic dye composition and an application thereof on dyeing fibers, and relates to an acidic dye composition and a dyeing application thereof. The red acidic dye composition comprises one or more dye compounds represented by the formula (I), one or more dye compounds represented by the formula (II), and one or more dye compounds represented by the formula (III), wherein the weight ratio of the dye compounds represented by the formula (I): the dye compounds represented by the formula (II): the dye compounds represented by the formula (III) is 20-40: 40-60: 5-10. The invention further discloses an application of the red acidic dye composition on dyeing nylon fibers. The red acidic dye composition has a synergistic effect; and the color, leveling dyeing property,permeability, lifting performance, and fastness are all improved.

Description

technical field [0001] The invention relates to an acid dye composition and its dyeing application, more specifically, it relates to a red acid dye composition and its dyeing application on fibers. Background technique [0002] The development of new red azo acid dyes with excellent dyeing properties and color fastness has always been an important research topic for current dye workers. [0003] It is understood that azo acid dyes refer to azo dyes that contain sulfonic acid groups or carboxyl groups in the molecule, and at the same time have hydroxyl groups in the ortho position of the azo group on the aromatic ring. The synthesis of acid mordant dyes is similar to that of other acid dyes, except that the substituents of diazo components and coupling components are different. Azo dyes are a class of dyes containing an amino chromophore in their molecules. They are the most diverse dyes in synthetic dyeing cards, accounting for more than half of the output in dye industry s...
