Abstract
The invention discloses positive ion black dye used to dye acrylics fabric. It is made up of 10-20 wt% yellow dye, 6-20% red dye, 20-40% blue dye and residual auxiliary agent. The invention has good level-dyeing property.
Description
Technical field
The present invention relates to a kind of cationic black dyes, especially a kind of cationic black dyes of excellent levelling property is specially adapted to the printing and dyeing of polyacrylonitrile material and modified dacron.
Background technology
The most frequently used measuring method of compatibility that several dyestuffs are pieced together when dying is the compatibility value method, represents its compatibility value with numerical value or English alphabet, and the dyestuff that compatibility value is identical can be pieced together and dyes.Compatibility value is big more, and the exhaustion speed of dyestuff is slow more, good level-dyeing property.Based on 3, level-dyeing property is not fine with the cationic black dyes compatibility value in the dyeing of domestic acrylic fibers and modified dacron, and also not having at present compatibility value is 5 cationic black dyes.Therefore each producer's urgent need searching compatibility value is 5 cationic black dyes.
Summary of the invention
The invention provides a kind of excellent levelling property, compatibility value and be 5 cationic black dyes.
Cationic black dyes of the present invention, form by following component:
Parts by weight are 10～20% the yellow dyes as structural formula (1)
Parts by weight are 6～20% the orchil as structural formula (2)

Surplus is an auxiliary agent.
Auxiliary agent of the present invention comprises one of following or its mixture: Sodium sulfate anhydrous.min(99), dextrin.
Compatibility value of the present invention is that 5 cationic black dyes can be pressed the method preparation:
Will be as the yellow dyes component of structural formula (1), as the orchil component of structural formula (2), measure in proportion after enter blender behind the abrasive dust, mixed 4～8 hours as blue dyes component, the auxiliary agent of structural formula (3).
The present invention selects the yellow dyes component as structural formula (1) for use, has in its structure
Orchil component as structural formula (2) has in its structure-C

4OH, the absorbing wavelength of these three kinds of dyestuffs is close, molecular weight is close, its compatibility value all is 5, thereby amalgamation has splendid level-dyeing property, and have resistance toheat good, to look rate height, characteristics such as coloured light is bright-coloured.
Compatibility value of the present invention is 5 cationic black dyes, can satisfy all compatibility value requirements and be 5 use occasion, in being particularly suitable for, light color.
Embodiment
Example 1～2
Press data shown in the table 1, will be as the yellow component of structural formula (1), as the red component of structural formula (2), behind the pulverizing mill abrasive dust, enter blender as blue component of structural formula (3) and auxiliary agent, mixed 4～8 hours, obtain compatibility value at 5 cationic black dyes.
Can select the gorgeous yellow E-4GL of positively charged ion of Zhejiang Province Runtu intercalated Co., Ltd's production for use as the yellow dyes component of structural formula (I); Can select for use Zhejiang Province Runtu intercalated Co., Ltd, Shanghai to celebrate into the positively charged ion fluorescent red E-4BL that chemical industry company limited produces as the orchil component of structural formula (II); Can select for use Zhejiang Province Runtu intercalated Co., Ltd, Shanghai to celebrate into the blue E-3RL of positively charged ion that chemical industry company limited produces as the blue dyes component of structural formula (III).

Mixture to the foregoing description preparation carries out the compatibility value detection, and detection method is: compatibility value exponential measuring method when the GB/T2400 cationic dyestuff dyes acrylic fibers.Compatibility value all is 5 after testing.
Mixture to the foregoing description preparation carries out Performance Detection, and detection method is: the measuring method of general condition regulation, GB2399 cationic dyeing coloured light and the intensity of GB2374 dyeing.
Observe cloth specimen coloured light and adopt standard GB 3920 textiles colour fastness to rubbing test methods, GB3921 textiles colour fastness to washing test method, its dyefastness of GB3922 textiles colour fastness to perspiration determination of test method.Measurement result sees Table 2.
