Abstract
The invention provides an active dye non-aqueous solvent dyeing method with high color fixation rate. The method comprises the following steps: swelling a cotton fabric in an aqueous solution of an alkaline substance until the moisture content is 30 to 200 percent, and then drying the cotton fabric; mixing the dried cotton fabric with active dye and good solvent of the active dye, adding poor solvent of the active dye in the heating process, and preserving the heat until the temperature reaches a dyeing temperature; placing the dyed cotton fabric in an organic solution with more than two nucleophilic group compounds, and preserving the temperature for a period of time; then placing the cotton fabric in an organic solution with more than two electrophilic group compounds to be reacted; taking out the cotton fabric, neutralizing and washing the cotton fabric, and completing the dyeing.

Description
Technical field
The present invention relates to a kind of colouring method of REACTIVE DYES, particularly a kind of REACTIVE DYES non-aqueous solvent dyeing method of high colour-fast rate, belongs to textile dyeing and finishing technical field.
Background technology
The dyeing of current COTTON FABRIC adopts REACTIVE DYES mostly, due to the hydrolysis of active group in aqueous medium in dyeing course, not only cause the waste of a large amount of REACTIVE DYES, and need consume a large amount 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 DYES exists all the time.
In order to avoid the hydrolysis of REACTIVE DYES, improve the utilization rate of REACTIVE DYES, scientists is being noted very early and have studied the dyeing of REACTIVE DYES in non-aqueous media.Adopt the advantage of non-aqueous media dyeing to be that REACTIVE DYES can not be hydrolyzed in dyeing course, be expected to the extent of reaction that can improve REACTIVE DYES and cotton fiber.But simultaneously, adopt non-aqueous media dyeing also to there is more problem always, mainly comprise the dissolubility of REACTIVE DYES in non-aqueous media, the Swelling Capacity of cotton fiber in non-aqueous media, the fixation alkaline agent solubility in non-aqueous media and the level-dyeing property, through-dyeing etc. of dyeing.Although REACTIVE DYES dyes and there is many difficult points in non-aqueous media, present stage use water cost raise gradually, and people more and more pay attention to environmental protection, and the dyeing of REACTIVE DYES non-aqueous media also more and more receives publicity with its good application prospect.
The eighties in last century, India's textile technology research institute adopted dimethyl formamide lytic activity dyestuff C.I. active red 12, and add trichloro-ethylene in batches and be incubated 1h being warming up in 80 DEG C of processes, dyestuff is completely upper dye almost, and degree of fixation is 84%.Though said method provides a good solvent dyeing thinking, it is little that degree of fixation compares advantage than conventional coloring method, and still need a large amount of water to carry out high temperature after dyeing and to soap removal loose colour, prospects for commercial application is little, is therefore further developed.
Solvent reverse micelle decoration method is a kind of novel non-aqueous solvent dyeing technique in recent years occurred, this method is that reverse micelle system fiber or fabric being placed in the aqueous dye solutions of solubilising high concentration dyes, greatly reduce compared with dyeing institute water consumption dyes 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, a large amount of surfactants and the consumption of auxiliary agent cause cloth specimen adsorbing a large amount of surfactants and auxiliary agent in dyeing course, can cause post processing difficulty, higher, the environmental pollution of COD value of waste water of soaping and certain wasting of resources equally.2, the affinity of high concentration aqueous dye solutions to cotton fiber owing to disperseing in dicyandiamide solution is high, and 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 can cause the hydrolysis of dyestuff equally, and therefore, its degree of fixation is lower.
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 DYES.REACTIVE DYES 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 equally because the affinity of dye granule to cotton fiber of disperseing in dicyandiamide solution is high, 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 REACTIVE DYES non-aqueous solvent dyeing technique has lot of documents report, but the degree of fixation of REACTIVE DYES is still lower, after dyeing, still need a large amount of water to wash away the loose colour on cotton fiber, this also just loses non-aqueous solvent dyeing real significance, simultaneously, because the affinity of dyestuff in dicyandiamide solution to cotton fiber is high, dyeing rate is wayward, causes easy dyeing flower of dyeing.
