Description
Technical field
It is special to be related to a kind of reactive dye solvent of good level-dyeing property the present invention relates to a kind of dyeing new method of reactive dye
New method is dyed, textile dyeing and finishing technical field is belonged to.
Background technique
The dyeing of reactive fibre at present mostly uses greatly reactive dye, in dyeing course in an aqueous medium due to active group
Hydrolysis, do not only result in the waste of a large amount of reactive dye, and need in dyeing course to consume a large amount of water and discharge is big
Reluctant high chroma sewage is measured, this, which is that reactive dye are all the time existing, is difficult to the bottleneck overcome.
In order to be avoided that the hydrolysis of reactive dye, the utilization rate of reactive dye is improved, scientists are very early
Paid attention to and has studied dyeing of the reactive dye in non-aqueous media.It is that reactive dye exist using the advantage that non-aqueous media dyes
It will not be hydrolyzed in dyeing course, be expected to that the extent of reaction of reactive dye and fiber can be improved.But meanwhile using non-aqueous media
Dyeing also always exists more problem, and the main dissolubility including reactive dye in non-aqueous media, fiber are in non-aqueous media
In solubility in non-aqueous media of Swelling Capacity, fixation alkaline agent and level-dyeing property, the through-dyeing of dyeing etc..Although active
Dyestuff dyes that there is many difficult points in non-aqueous media, but is gradually risen at this stage with water cost and people protect environment
Shield increasingly pay attention to, reactive dye non-aqueous media dyeing with its good application prospect also more and more attention has been paid to.
Reactive dye C.I. active red is dissolved using dimethylformamide in India's textile technology research institute eighties in last century
12, trichloro ethylene is added portionwise during being warming up to 80 DEG C and keeps the temperature 1h, the almost upper dye of dyestuff, degree of fixation 84%.
Though the above method provides a preferable solvent dyeing thinking, degree of fixation is more little compared to advantage than conventional coloring method, dye
It soaps after color there is still a need for a large amount of water progress high temperature and removes loose colour, prospects for commercial application is little, therefore is not further developed.
Solvent reverse micelle decoration method is the novel non-aqueous solvent dyeing technique of one kind occurred in recent years, the method be by fiber or
It is dyed in the reverse micelle system for the aqueous dye solutions that fabric has been placed in high concentration solubilized, dyeing institute's water consumption and traditional water bath dye
Compared to greatly reducing, a kind of novel water-saving dyeing of can yet be regarded as.But there are the following problems for reverse micelle dyeing: 1,
System internal surfactants and the dosage of cosurfactant are larger, and the dosage of a large amount of surfactant and auxiliary agent causes
A large amount of surfactant and auxiliary agent are adsorbed in dyeing course on cloth specimen, equally will cause post-processing difficulty, waste water COD of soaping
It is worth higher, environmental pollution and certain wasting of resources.2, since the high concentration aqueous dye solutions dispersed in dicyandiamide solution are to fibre
The affinity of dimension is high, therefore dyestuff dyeing speed is fast, is difficult to control, easy dyeing flower.3, cotton fiber needs to pad first certain when dyeing
The aqueous sodium carbonate of concentration, and enter dye to liquid rate with certain, water present in system also results in the hydrolysis of dyestuff, because
This, degree of fixation is lower.
In order to overcome reverse micelle system to dye drawback, Yida Textile Co., Ltd and Institutes Of Technology Of Zhejiang develop cooperatively
Organic solvent suspension system realizes the dyeing of reactive dye.The dyeing is by reactive dye and a certain amount of dispersing agent
It is scattered in organic solvent system by ball milling, the upper dye to cotton fiber is realized under certain dyeing condition.In the dyeing
The dispersing agent of use is only 0.15 times of dye dosage, and the dye-uptake of dyestuff can reach nearly 100%, has been fully demonstrated non-aqueous
The advantage of agent dyeing, but also due to the dye granule dispersed in dicyandiamide solution is high to the affinity of cotton fiber, therefore upper dye is fast
Degree is fast, and easy dyeing flower, equally, water present in system will lead to the hydrolysis of dyestuff, and dye utilization rate is low.
Since the inorganic base substance (such as sodium carbonate, sodium hydroxide) of reactive dye color fixing in dicyandiamide solution is all insoluble
Solution, it is therefore desirable to will first be dried again with the dye preparatory alkali process of object, and then add in solvent and dye, dyestuff is anti-to what is alkalized
Answer speed especially fast, it cannot be as in aqueous medium by slowly adding alkali to control reactive dye reaction speed, therefore dyeing rate
It is not easy to control, cause to dye easy dyeing flower, and upper alkali drying process CIMS is cumbersome in advance, time-consuming and drying needs additional energy source.
Summary of the invention
To solve the above-mentioned problems, the purpose of the present invention is to provide a kind of reactive dye solvent dyeing of good level-dyeing property is new
Method, which is not necessarily to pre- upper alkali process, and controls the adding manner of inorganic base, has overall flow short, dyestuff is anti-
