Description
Technical field
The present invention relates to the colouring method of a kind of reactive dye, particularly to a kind of reactive dye non-aqueous solvent dyeing method of high colour-fast rate, belong to textile dyeing and finishing technical field。
Background technology
The dyeing of current reactive fibre adopts reactive dye mostly, due to active group hydrolysis in aqueous medium in dyeing course, not only result in the waste of a large amount of reactive dye, and need consume substantial amounts of water and discharge a large amount of reluctant high chroma sewage in dyeing course, this is the bottleneck being difficult to overcome that reactive dye exist all the time。
In order to be avoided that the hydrolysis of reactive dye, improving the utilization rate of reactive dye, scientists is very early it have been noted that and have studied reactive dye dyeing in non-aqueous media。The advantage adopting non-aqueous media dyeing is in that reactive dye will not be hydrolyzed in dyeing course, is expected to the extent of reaction that can improve reactive dye with fiber。But simultaneously, adopt non-aqueous media dyeing also to there is more problem always, mainly include reactive dye dissolubility in non-aqueous media, the fiber Swelling Capacity in non-aqueous media, the fixation alkaline agent dissolubility in non-aqueous media and the level-dyeing property of dyeing, through-dyeing etc.。Although reactive dye dye in non-aqueous media there is many difficult points, but present stage use water cost gradually rises, and environmental conservation is increasingly paid attention to by people, and the dyeing of reactive dye non-aqueous media also increasingly receives publicity with its good application prospect。
The eighties in last century, India's textile technology institute adopted dimethylformamide lytic activity dyestuff C.I. active red 12, is dividedly in some parts trichloro ethylene and is incubated 1h in being warming up to 80 DEG C of processes, and dyestuff is completely upper dye almost, and degree of fixation is 84%。Though said method provides a good solvent dyeing thinking, but degree of fixation to compare advantage than conventional coloring method little, remain a need for substantial amounts of water after dyeing and carry out high temperature and soap removal loose colour, prospects for commercial application is little, is therefore developed further。
Solvent reverse micelle staining is a kind of novel non-aqueous solvent dyeing technique in recent years occurred, this method be the aqueous dye solutions that fiber or fabric are placed in solubilising high concentration reverse micelle system in dyeing, dyeing institute water consumption greatly reduces compared with dyeing with traditional water bath, a kind of novel water saving dyeing of can yet be regarded as。But there is following problem in reverse micelle dyeing: 1, the large usage quantity of system internal surfactants and cosurfactant, the consumption of substantial amounts of surfactant and auxiliary agent causes adsorbing on cloth specimen in dyeing course substantial amounts of surfactant and auxiliary agent, can cause post processing difficulty equally, COD value of waste water of soaping is higher, environmental pollution and certain wasting of resources。2, owing to high concentration aqueous dye solutions scattered in dicyandiamide solution is high to the affinity of fiber, therefore dyestuff dyeing speed is fast, wayward, easy dyeing flower。3, during dyeing, first cotton fiber needs to pad certain density aqueous sodium carbonate, and enters dye with certain liquid rate for the treatment of, the water existed in system also results in the hydrolysis of dyestuff, and therefore, its degree of fixation is relatively low。
In order to overcome reverse micelle system dyeing drawback, Yida Textile Co., Ltd and Institutes Of Technology Of Zhejiang have developed organic solvent suspension system cooperatively to realize the dyeing of reactive dye。Reactive dye and a certain amount of dispersant are scattered in organic solvent system by ball milling by this dyeing, realize the upper dye to cotton fiber under certain dyeing condition。The dispersant adopted in this dyeing is only 0.15 times of dye dosage, and the dye-uptake of dyestuff can reach nearly 100%, fully demonstrate the advantage of non-aqueous solvent dyeing, but also due to scattered dye granule is high to the affinity of cotton fiber in dicyandiamide solution, therefore dyeing speed is fast, easy dyeing flower, equally, the water existed in system can cause the hydrolysis of dyestuff, and dye utilization rate is low。
Although the existing lot of documents report of reactive dye non-aqueous solvent dyeing technique, but the degree of fixation of reactive dye is still relatively low, the substantial amounts of water loose colour to wash away on fiber is remained a need for after dyeing, this also just loses non-aqueous solvent dyeing real significance, simultaneously, owing in dicyandiamide solution, dyestuff is high to the affinity of fiber, dyeing rate is wayward, causes easy dyeing flower of dyeing。
