The composition of cobaly blue dispersed dye utilizes anthraquinone dye and azo dye to complement mutual advantages, the obtained composition of the cobaly blue dispersed dye has good fastness and dyeing performance, increases dyeing capability of the dye, particularly improves sublimation fastness of the dye, overcomes the defects in C.1. dispersed blue 56, simultaneously improves wash fastness, and has wide application prospect.
Description
Technical field
The present invention relates to a kind of disperse dye composition of bright blue coloured silk, belong to the dyeing and the printing technique field that contain polyester textile.
Background technology
In dispersed dye, C.1. Disperse Blue-56 is acknowledged as bright-coloured and strong EX-SF DISPERSE BLUE EX-SF 300, widely uses both at home and abroad.But this dye sublimation fastness is low, can produce look change and contamination in the heat arrangement process of pad-dry-cure dyeing or DYED FABRICS, makes the downgrade of DYED FABRICS, so the scope of its use is restricted.Provide a kind of gorgeous blue color strong EX-SF DISPERSE BLUE EX-SF 300 for this reason, improve its sublimation fastness, make it to be suitable for simultaneously energy-conservation continuous dyeing in warm molten dyeing and stamp, particularly necessary to overcome the deficiency that Disperse Blue-56 C.1. exists.
Summary of the invention
In order to overcome above-mentioned problems of the prior art, the invention provides a kind of disperse dye composition of bright blue coloured silk, this dye composite should have good good fastness and colouring power, and that promotes dyestuff gives the look ability.
Technical scheme of the present invention is: a kind of disperse dye composition of bright blue coloured silk contains:

3Be methyl or ethyl;
(c) a kind of 0～10% formula (III) and formula (IV) or 2～3 kinds of azo heterocyclic dye structures:
In the formula: R
4Be hydrogen or chlorine atom;
(d) 0～50% formula diffusant:
Its diffusant is sodium lignosulfonate, dispersing agent MF or two kinds of diffusant mixtures;
Described (a) and (b), (c) and (d) shown in the total amount of component be 100%.
Described dye composite is selected commercial dye for use:
(1) Disperse Blue-60 200% C.1.
(2) EX-SF DISPERSE BLUE EX-SF 300 183:1200% C.1.
(3) DISPERSE Yellow 211 C.1.
In the disperse dye composition of bright blue coloured silk, (I-1) be: (I-1) account for 40～60%, (II-1) account for 60～40% with (II-1) weight ratio; Gross weight with final dye composite is a benchmark, is 0～10% (III-1), and diffusant is 0～50%, and its composition (I-1), (II-1), (III-1) are 100% with the summation of diffusant.
Described dye composite is selected commercial dye for use::
(1) Disperse Blue-60 200% C.1.
(2) EX-SF DISPERSE BLUE EX-SF 300 257 C.1.
(3) DISPERSE YELLOW 114 C.1.
In the disperse dye composition of bright blue coloured silk, (I-1) be: (I-1) account for 30～50%, (II-2) account for 70～50% with (II-2) weight ratio; Gross weight with final dye composite is a benchmark, is 0～10% (IV), and diffusant is 0～50%, and the summation of its composition (I-1), (II-2), (IV) dyestuff and diffusant is 100%.
Gross weight with described dye composite is a benchmark, and wherein the former dyestuff of synthetic accounts for 20～60%, and diffusant accounts for 40～80%.
Described dye composite is used to contain the dyeing and the stamp of polyester textile.
The invention has the beneficial effects as follows: the disperse dye composition of this bright blue coloured silk utilizes anthraquinone dye and azoic dyestuff to have complementary advantages, the disperse dye composition of the bright blue coloured silk that obtains has good all fastness and dyeing behavior, and that has promoted dyestuff gives the look ability; Especially improve the sublimation fastness of dyestuff, overcome the C.1. deficiency of Disperse Blue-56 existence; Improved washing fastness simultaneously, this dye composite is with a wide range of applications.
Embodiment
This dye composite adopts conventional preparation: form as each component being mixed by said ratio with commercial dye; Or after each component being mixed by said ratio with the former dyestuff of synthetic conversion back, through sand milling, dried the forming of spray.The formulation of its dyestuff can be liquid state, powdery or granular.Therefore, above-mentioned dye composite contains by weight: 20～60% synthetic former dyestuff and 40～80% diffusant.
The present invention will be further described below in conjunction with specific embodiment, but protection scope of the present invention is not limited to this.
Commercial dye and chemical structure that the embodiment of the invention is used are as follows:
Dyestuff 1C.1. Disperse Blue-60 200%
Dyestuff 2C.1. EX-SF DISPERSE BLUE EX-SF 300 183:1200%
Dyestuff 3C.1. EX-SF DISPERSE BLUE EX-SF 300 257
