Description
Technical field
The present invention relates to staining technique fields more particularly to the novel two-bath process of a kind of polyester-cotton blend disperse dyes and reactive dye to contaminate
Color technique.
Background technique
Traditional dyeing and finishing industry is blended to polyester-cotton blend or intertexture dyes, and is dyed using two one bath two-step of Dyeing with Disperse/Reactive always
Method uses disperse dyeing of polyester-reduction cleaning-reactive dye resisdye cotton method, the entire dyeing time will reach 10
Multiple hours, production efficiency is low, and water, electricity, vapour consumption are big, and quantity of wastewater effluent is big, and since the wet-milling product time is long, easily makes cloth cover
Fluffing and influence fabric feeling, decline product quality and Business Economic Benefit.
Existing Dyeing with Disperse/Reactive one-bath dyeing substitution two one bath two-step of Dyeing with Disperse/Reactive dyeing, although can be
The two-bath process institute problem is avoided to a certain extent, but there is also largely ask for Dyeing with Disperse/Reactive one-bath process method
Topic, such as the limitation of reactive dye used and disperse dyes are very big, and either reactive dye or disperse dyes all need
Certain specific dyeability requirements, do not have extensive use value, and usually will appear dyestuff hydrolysis, and colouring is uneven,
The defects of generation dyeing defect, color difference, degree of fixation is low.
It would therefore be highly desirable to develop a kind of technology of polyester-cotton fabric disperse and activity high-efficient, the time is short and colouring is uniform, degree of fixation is high
Dyeing technique.
Summary of the invention
The problem of based on background technique, the invention proposes a kind of polyester-cotton blend disperse dyes and reactive dye two-bath process
Dyeing, not only high production efficiency, process flow are short, but also paint uniformly, and color fastness is high.
The invention proposes a kind of polyester-cotton blend disperse dyes and the novel two bath process technique of reactive dye, including walk as follows
It is rapid:
S1, dye are washed: polyester-cotton fabric being immersed in microcapsule disperse dye dye liquor, adjusting bath raio is 1:5-20, with 2-3
DEG C/rate of min is warming up to 120-130 DEG C, 45-55min is kept the temperature, then be cooled to 70-80 DEG C with the rate of 1-2 DEG C/min, protected
Warm 5-15min, is cooled to room temperature, and washes, drying；
S2, dye cotton: the polyester-cotton fabric washed through S1 dye is immersed in comprising 2,3- epoxypropyltrimethylchloride chloride
In finishing fluid, 50-60min is kept the temperature after being warming up to 70-80 DEG C, is immersed in reactive dye dye liquor again after taking out washing, and bath is adjusted
Than being warming up to 70-80 DEG C with the speed of 1-2 DEG C/min for 1:30-40,10-20min is kept the temperature, then press the body of reactive dye dye liquor
The soda ash of 5-20g/L is added in product, keeps the temperature 25-35min, is cooled to room temperature, and washes, soaps, and dries.
Preferably, the microcapsule disperse dye dye liquor includes: microcapsule disperse dye 1-5% (owf), pH buffer 1-
3g/L, levelling agent 1-2g/L.
Preferably, preparing the microcapsule disperse dye includes: to be added to the water beta-cyclodextrin, add citric acid and time
The weight ratio of sodium phosphite, beta-cyclodextrin, citric acid and sodium hypophosphite is 9-12:3-5:1, is stirred after being warming up to 90-100 DEG C
1-2h is reacted, it is cooling, it filters, after being recrystallized with the mixed solvent of water and acetone, obtains citric acid-beta-cyclodextrin esterification
Object；The citric acid-beta-cyclodextrin carboxylate is soluble in water, the ethanol solution dissolved with disperse dyes, disperse dyes, β-are added
The weight ratio of cyclodextrin is 1:3-10, and 1-2h is stirred to react after being warming up to 50-60 DEG C, removes solvent, obtains the disperse dyes
Microcapsules.
Preferably, the disperse dyes are ahthraquinone disperse dye, preferably disperse red E-3B, Disperse Blue 2BLN, dispersion
At least one of emerald green orchid S-GL.
Preferably, in S1, washing temperature is 50-60 DEG C, time 5-15min；Drying temperature is 90-100 DEG C.
Preferably, described include the finishing fluid of 2,3- epoxypropyltrimethylchloride chloride includes: 2,3- glycidyl front three
Ammonium chloride 5-15g/L, sodium hydroxide 15-25g/L.
Preferably, the concentration of reactive dye is 1-5% (owf) in the reactive dye dye liquor.
Preferably, the reactive dye are that vinyl sulfone(RemzaolHuo Xingranliaohuoxingjituan) class reactive dye or one chloro-s-triazine/vinyl sulfone double-active base class are living
Property dyestuff；Preferably, the reactive dye are at least one of active red KE-3B, active yellow KD-3G, Reactive Turquoise Blue KN-G.
Preferably, in S2, washing temperature is 30-50 DEG C, time 5-15min；Temperature of soaping is 90-100 DEG C, when soaping
Between be 5-15min.
The present invention proposes a kind of polyester-cotton blend disperse dyes and the novel two bath process technique of reactive dye, first to polyester-cotton fabric into
Row disperse dyeing, by being dyed using micro-encapsulation disperse dyes, the microcapsule disperse dye is by utilizing lemon
Beta-cyclodextrin after lemon is Esterification includes disperse dyes, β-ring paste in high-temperature dyeing procedure, after β Citrin ester
Essence can also be reacted with the hydroxyl on polyester fiber, thus by cyclodextrin essence anchor on to dyeing and weaving object, due to hydrophilic β-ring
Dextrin will not have an impact the surface hydrophilic performance of polyester-cotton fabric, therefore be conducive to the upper of the disperse dyes included in capsule
Dye；And since beta-cyclodextrin includes disperse dyes, it may not be necessary to which in addition adding auxiliary agent can be so that dispersion
Dyestuff obtains good dye-uptake.This microcapsule disperse dye body has excellent slow-release function simultaneously, therefore can be to upper
Dye speed is controlled, to have good even dyeing effect, by the isolation performance using microcapsules, is not needed using dispersion
The processes such as the auxiliary agents such as agent and reduction cleaning, can achieve the purpose that level dyeing and high color fastness, therefore reduce dyeing process
Meanwhile dyeing time can also shorten, utilization rate of equipment and installations and worker's production efficiency are greatly enhanced.
Hereafter the present invention carries out reactive dyeing to polyester-cotton fabric, by being immersed in polyester-cotton fabric comprising 2,3- epoxy
In the finishing fluid of hydroxypropyltrimonium chloride, since anchor smart on fabric has cyclodextrin molecular, with easily with 2,3- epoxy
Hydroxypropyltrimonium chloride carries out necleophilic reaction, so that polyester-cotton fabric has positive electricity performance, on the one hand can contaminate with activity
Anion on material combines, and greatly reduces the hydrolysis property of reactive dye, on the other hand significantly improves dyestuff pair again
The affinity of polyester-cotton fabric fiber, so as to which the reactive dye in dye liquor are further adsorbed on polyester-cotton fabric fiber, after
Continuous and polyester-cotton fabric fiber-reactive, further increases the degree of fixation of reactive dye；And due to polyester-cotton fabric and reactive dye
Absorption, can effectively improve the upper dye efficiency of reactive dye, therefore can avoid the use of a large amount of salt, hence it is evident that lower the pollution of dye bath
Property.
