Problems solved by technology

[0003] The reactive dye in the related art is a black dye composition, which is a double active group reactive dye composition composed of reactive black 5# and reactive orange 13#, which has a more distinct jet black color through the compounding of the two degree, but the above-mentioned black dyes generally have defects such as poor lifting power, low dyeing rate and color fixation rate in the actual application process, and the color fastness of each item is poor
[0004] Especially when the above-mentioned black dye composition needle is applied to the dyeing of blended fibers, the color fastness can only be guaranteed by compounding the two-bath method, which then significantly increases the working intensity of the dyeing. If the one-bath method is used for dyeing, the various items Performance will be further reduced, so there is an urgent need to provide a black dye composition with good dyeing performance and color fastness, and suitable for one-bath dyeing

Embodiment 1-10

[0068] A black dye composition, calculated on a total weight of 100kg, composed of one or more dye compounds represented by general formula (I), one or more dye compounds represented by general formula (II) and one or more The composition of the dye compound represented by formula (III) is obtained by grinding for 45 min under the condition of 2000r / min, and its consumption and the dye compound represented by each general formula are shown in the following table: Table: each component and content (kg) in the black dye composition )

[0069]

[0070] Note: the color and luster of the black dye composition of the embodiment of the present application can be adjusted by the ratio of general formula (I), general formula (II), general formula (III) dyestuff, and above-mentioned ratio can guarantee its black color and luster, also can It can endow the black dye composition with better color fastness, and it is not easy to decolorize after it is applied to the dyed object.

Embodiment 11-15

[0072] A kind of black dye composition, calculates by gross weight 120kg, and the difference with embodiment 1 is, also comprises the orange reactive dye of 20kg, grinds 45min and obtains under the condition of 2000r / min, its consumption and each general formula represent The dye compounds are shown in the table below:

Abstract

The invention relates to the technical field of dyes, in particular to a black dye composition and application thereof. The black dye composition comprises one or more dye compounds represented by a general formula (I), one or more dye compounds represented by a general formula (II) and one or more dye compounds represented by a general formula (III). According to the black dye composition disclosed by the invention, through compounding of the dye compounds, the dyeing performance and the dyeing fastness of a blended fabric can still be well guaranteed when the blended fabric is efficiently dyed by using a one-bath process.

Description

technical field [0001] The application relates to the technical field of dyes, more specifically, it relates to a black dye composition and its application. Background technique [0002] With the improvement of people's living standards, people have increasingly stringent requirements for the performance of printed and dyed fabrics. Therefore, how to ensure the dyeing quality of printed and dyed fabrics has become the primary technical problem to be solved. Among them, reactive dyes that have emerged in recent years are examples. It has the characteristics of bright color, excellent application performance, convenient use and strong applicability. [0003] The reactive dye in the related art is a black dye composition, which is a double active group reactive dye composition composed of reactive black 5# and reactive orange 13#, which has a more distinct jet black color through the compounding of the two However, the above-mentioned black dyes generally have defects such as ...
