Description
Technical field
The invention belongs to printing technology fields, are related to a kind of dyeing of cotton fabric, and in particular to a kind of cotton is fine
Tie up few water dyeing of fabric.
Background technique
Dip method progress is usually taken in traditional cotton fabric dyeing, and cotton fabric is immersed in reactive dye dye bath
And add alkali fixation, to form firm covalent bond in cotton fiber row.However, in dyeing course, cotton fiber and the equal band of dyestuff
Negative electrical charge, it is necessary to the electrical charge rejection effect that electrolyte such as anhydrous sodium sulphate etc. weakens the two be added.The use of a large amount of electrolyte is no doubt
The dye-uptake of cotton fiber is improved, but can not recycle and degrade, causes modifying porcelain difficult.In addition to electrolyte, dye
Color waste water usually also comprising not fixed dyestuff more than one third, causes dyeing waste-water COD value to be up to 104mg/L.Therefore, it contaminates
Color waste water is always a great problem for perplexing dyeing.
In order to solve wastewater problem from the root, people gradually develop a variety of based on non-aqueous solvent system or few aqueous solvent
The colouring method of system, such as supercritical CO2Dyeing, organic solvent dyeing, suspension system dyeing and reverse micelle dyeing.These dyes
Color method, as dyeing medium, avoids or reduces the usage amount of water by using other dicyandiamide solutions substitution water；It can also subtract simultaneously
The usage amount of few salt.It among these, the use of more dicyandiamide solution is atoleine and organosiloxane.
Chinese patent application CN106368016A discloses a kind of atoleine colouring method of cotton fiber, and the method will
Leuco vat dye is scattered in atoleine, and in dyeing course, leuco vat dye is spontaneously transferred to cotton fiber
Above and through being contaminated in oxidation.Dyestuff dye-uptake is high, and auxiliary agent consumption is few, and dyeing is simple.However, the level-dyeing property of this method is not
It is good, while wet friction color fastness is poor.
Chinese patent application CN101922121B discloses a kind of non-aqueous dyeing method of reactive dye to textile, the party
Method by reactive dye, surfactant, coupling agent and as solvent cyclic methyl siloxane mix, make active dye by ball milling
Material is evenly dispersed in cyclic methyl siloxane, stable dye media suspension system dye bath is prepared into, using certain dye
Color technique is dyed.The not salt-free dyeing using water as the reactive dye of medium to cellulose fibre may be implemented in this method, Du
Exhausted electrolyte pollution, and dyestuff hydrolysis is greatly decreased, improve dyestuff fixation rate.The wet friction color fastness of this method and traditional water
Bath dyeing method is suitable, but still the level-dyeing property problem of unresolved dyestuff.
In view of the above drawbacks of the prior art, it is still desirable to for the dye based on non-aqueous solvent system or few aqueous solvent
Color technique makes sustained improvement.
