Abstract
The invention discloses a composite active red dye which comprises the following components in percentage by weight: 60-90 percent of dye monomer A shown as the formula (1), 10-40 percent of dye monomer B shown as the formula (2) and 0-10 percent of dispersing agent MF and/or diffusant NNO. The composite active red dye can obtain higher dyeing level and bright colors when being used for dyeing cotton, hemp and viscose glue, and the friction resistant fastness and the perspiration and soaping resistant fastness can meet the standard requirement.
Description
Technical field
The present invention relates to a kind of reactive dyestuffs, a kind of specifically composite active red dye is applicable to dyeing such as cotton, fiber crops, gluing fiber.
Background technology
The orchil of generally producing and using---reactive red B-4BD is a kind of colorant match dye composition in the market, and its fastness, thermostability and alkali resistance are all relatively poor, and dust is big when using, not easy cleaning.
Along with the raising day by day of standard of living, people are also more and more higher to the requirement of textile product, thereby the requirement of reactive dyestuffs on every performance that is used in textile dyeing is harsh day by day.Reactive dyestuffs not only will have excellent dyefastness and dyeing behavior, and want compliance with environmental protection requirements.
Summary of the invention
The invention provides a kind of degree of fixation height, composite active red dye that utilization ratio is high, and be an environmental protection dyestuff that reaches the ecological textile examination criteria.
A kind of composite active red dye, by weight percentage, composed of the following components:
60-90% dye monomer A as the formula (1):
10-40% dye monomer B as the formula (2):
0～10% Dispersant MF and/or dispersing agent NNO.

A kind of preferred composite active red dye, by weight percentage, composed of the following components: 60-85% dye monomer A as the formula (1); 10-30% dye monomer B as the formula (2); 5～10% Dispersant MFs and/or dispersing agent NNO increase additive compound, have increased colorant dissolubility, have improved degree of fixation, have improved the utilization ratio of dyestuff, reach the ecological textile examination criteria.
Composite active red dye of the present invention can prepare with ordinary method, as in required ratio mechanically mixing colouring agent monomer A, dye monomer B and auxiliary agent, or piece together mixedly in mode well known in the art, wherein dye monomer can exist with powdery, resulting solution or its aqueous solution form; Auxiliary agent can be plentiful and substantial with the form of powdery, solution.Dye monomer A, dye monomer B can adopt the commercially available prod, also can adopt method well known in the art to be prepared; Auxiliary agent can be directly in market purchasing.
Every performance of composite active red dye of the present invention all is better than reactive red B-4BD, when improving product component, can increase additive compound, thereby increased colorant dissolubility, improved degree of fixation, improved the utilization ratio of dyestuff, reach the ecological textile examination criteria, the textiles foreign trade is detected can be passed through smoothly.It is bright in luster to obtain the high dyeing degree of depth when composite active red dye is used for cotton, fiber crops, dying viscose glue, and fastness to rubbing, perspiration resistance, soaping fastness can both reach standard-required.
Embodiment
The invention will be further described below in conjunction with embodiment and ratio.But protection scope of the present invention is not limited thereto.
Embodiment 1～13
According in table 1-1, table 1-2 and the table 2 shown in the data, after dye monomer A, dye monomer B and solubility promoter and water mixed, grind dispersion with sand mill, carry out spraying drying then.
Dye monomer A, dye monomer B can adopt method well known in the art to be prepared, for example: the preparation process of the dye monomer A among the embodiment 5 is: primary condensation is carried out in cyanuric chloride and H acid at low temperatures, after primary condensation finishes, intensification is carried out the secondary condensation with H acid again, gets intermediate after the secondary condensation finishes; The para-ester that adds calculated amount in the doazo reaction pot after the cooling making beating adds hydrochloric acid, adds Sodium Nitrite and carries out diazotization reaction, and diazotization reaction is carried out coupling with diazonium liquid and intermediate after finishing, and coupling promptly gets required dye monomer A after finishing.
The preparation process of dye monomer B among the embodiment 5 is: para-ester is added Sodium Nitrite carry out diazotization reaction in hydrochloric acid, diazotization finishes back adding J acid and carry out a coupling under acidic conditions, gets the dyestuff intermediate product after a coupling finishes; The Ke Lixiding para-ester of the calculated amount back of pulling an oar in the diazonium pot is added hydrochloric acid cooling back and adds Sodium Nitrite and carry out diazotization reaction, after diazotization reaction finishes, to carry out the secondary coupling in the diazonium liquid adding dyestuff intermediate, the secondary coupling promptly gets required dye monomer B after finishing.
Table 1-1
Table 1-2
Table 2
The reactive dyestuffs that the foregoing description is made adopt the test of dyeing of the reactive dyestuffs of standard, must its corresponding performance datas, see Table 3.
Table 3
Detect data analysis by table 3, the composite active red dye K/S value that the present invention obtains is higher, and every colour fastness is better, the red bright-coloured chromatogram that can satisfy the demand.
