Summary of the invention
For the deficiencies in the prior art, an object of the present invention is that providing a kind of glues/bright and beautiful blending silk thread activity/ACID DYES One Bath Dyeing Process.Described technique is by the research to pH, alkaline agent, electrolyte, color-fixing agent, dyeing temperature in early stage, different temperature retention time, establish mixed dye optimum dyeing technique, make to glue/brocade two kinds of fibers obtain good homochromatism when one-bath process, and obtain higher dye-uptake and soaping fastness.
One glues/bright and beautiful blending silk thread activity/ACID DYES One Bath Dyeing Process, it is characterized in that:
Prescription is: active red EF-6B REACTIVE DYES 1.8-2.2%(o.w.f.)., the red B125% ACID DYES 1.8-2.2%(o.w.f. in pula), cushioning liquid made by soda ash 18-22g/l, glauber salt 1.8-2.2g/l, color-fixing agent 2.8-3.2g/l and acetic acid/sodium acetate; Bath raio is 45-55:1,
Technological process is: preparation dye bath (REACTIVE DYES, ACID DYES, glauber salt), when 35-45 DEG C, viscose cotton blended yarn line enters dye, adds alkali after constant temperature dyeing 30min, continues constant temperature 30min and makes reactive dye color fixing, then use acetic acid/sodium acetate buffer adjust ph to 5.5-6.5, slow intensification (2 DEG C/min), to boiling, is cooled to 75-85 DEG C after dye of boiling 15-25min, adds color-fixing agent fixation 15-25min, washing, soap boiling, post processing, completes whole dyeing course.
Wherein, the optimised process of sticky/bright and beautiful blending silk thread activity/ACID DYES one-bath dyeing is:
Prescription is: active red EF-6B REACTIVE DYES 2%(o.w.f.)., the red B125% ACID DYES 2%(o.w.f. in pula), cushioning liquid made by soda ash 20g/l, glauber salt 2g/l, color-fixing agent 3g/l and acetic acid/sodium acetate; Bath raio is 50:1,
Technological process is: preparation dye bath (REACTIVE DYES, ACID DYES, glauber salt), in 40 DEG C time, viscose cotton blended yarn line enters dye, adds alkali, continue at 40 DEG C of constant temperature 30min and make reactive dye color fixing after constant temperature 40 DEG C dyeing 30min, then acetic acid/sodium acetate buffer adjust ph to 6 is used, slow intensification (2 DEG C/min), to boiling, is cooled to 80 DEG C after dye of boiling 20min, adds color-fixing agent fixation 20min, washing, soap boiling, post processing, completes whole dyeing course.
The present invention is described in detail below:
（1）pH
PH value is many-sided on the impact that mixed dye dyes, may have following some: on dye solubility impact, pH value increase, solubility increase; On impact ACID DYES and REACTIVE DYES and hydrolised dye thereof contaminating polyamide fibre, pH reduces, and in ACID DYES, dye improves; On the impact of reactive dye color fixing, alkali condition, the degree of fixation of cellulose and poly-phthalein amine improves.
Mixed dye dye-uptake is the overall result that active and acid two dyestuff dye-uptakes and pH value change, and generally speaking, pH value is lower, and in ACID DYES, dye impact is large, and pH value is higher, and REACTIVE DYES impact is large.
The present invention finds through large quantifier elimination: adjust after fixation pH to 6 time homochromatism best, dye-uptake and soaping fastness are also relatively good, thus dyeing the later stage optimal pH be 6.
(2) alkaline agent
The alkaline agent of the present invention is soda ash.The dye-uptake impact of alkaline agent on mixed dye is not clearly, but comparatively large on the dye-uptake impact of REACTIVE DYES and ACID DYES, but generally speaking, alkaline agent consumption is too low or the too high impact on homochromatism is still more remarkable.
Soda ash, in the dyeing of REACTIVE DYES to viscose glue, plays tint retention.When soda ash consumption is less than 15g/L, concerning this consumption the upper dye of REACTIVE DYES not enough, make the dye-uptake of REACTIVE DYES lower.REACTIVE DYES contaminates the optimal fixation pH value of cellulose fibre about 10.5, and pH value when soda ash is 20g/L is 10.3, now can obtain good colour fixation rete and fixation efficiency.Along with the increasing of soda ash consumption, colour fixation rete improves constantly, but dyestuff hydrolysis rate also accelerates simultaneously.And the resistance to alkali hydrolysis property of its D-F key of REACTIVE DYES of ethene alum type is poor, so alkaline agent consumption is too high may affect scission of link fastness.
Generally speaking, the upper dye of ACID DYES is unfavorable under alkali condition.When soda ash consumption is respectively 5g/L, during 20g/L, dye-uptake is relatively high.This may be react because of the HAc/NaAc added during adjust ph in the Na2CO3 added and subsequent technique, constitute electrolytical feature, with electrolytical form, effect is played to dyeing circumstances, and the electrolytical upper dye being beneficial to ACID DYES that has, so Na2CO3 is 5g/L, during 20g/L, the dye-uptake of ACID DYES is higher.But when alkaline agent consumption is too high, the ionic bond that ACID DYES acts on nylon fibre may be destroyed.
Mixed dye dye-uptake is the overall result that active and acid two dyestuff dye-uptakes and pH value change, and generally speaking, pH value is lower, and in ACID DYES, dye impact is large, and pH value is higher, and REACTIVE DYES impact is large.
As mentioned above, in conjunction with homochromatism, the considering of dye-uptake and soaping fastness three, show that the soda ash consumption of this dyeing is advisable with 20g/L.
(3) electrolyte
Electrolyte of the present invention is glauber salt.Electrolytical impact is also many-sided, mainly contain following some: on the impact of colorant dissolubility, electrolyte concentration raises, and the solubility of dyestuff in dye liquor reduces; On impact ACID DYES contaminating polyamide fibre, at acid medium, electrolyte concentration is high, and dyeing rate is slow, and dye-uptake is low.At alkaline medium, dyeing rate and dye-uptake all improve; On the impact that REACTIVE DYES contaminates, electrolyte concentration improves, and dyeing rate and dye-uptake all improve; On the impact of REACTIVE DYES (comprising its hydrolised dye) upper dye polyamide fibre, be similar to the impact of ACID DYES.
The present invention finds through large quantifier elimination: the consumption of glauber salt is that 20g/L is better, and its homochromatism and soaping fastness are also relative better, so the optimum glauber salt consumption of this technique is 20g/L.
(4) color-fixing agent
The use of color-fixing agent makes the dye-uptake of mixed dye increase, but impact is not very remarkable, especially on the dye-uptake nothing impact of REACTIVE DYES.But the words that color-fixing agent consumption is too high may impel ACID DYES to have gathering to a certain degree.In addition, the use of color-fixing agent increases to soaping fastness, but does not make significant difference to homochromatism.
The present invention finds through large quantifier elimination: show that color-fixing agent consumption is advisable with 3g/L.
(5) dyeing temperature in early stage
Dyeing temperature major effect in early stage is: acid different with the dyeing rate of REACTIVE DYES, REACTIVE DYES dyeing rate is fast, and dye-uptake increases.On impact that is acid and REACTIVE DYES equilibrium adsorption, temperature is high, and balance dye-uptake reduces.Colorant dissolubility affects, and temperature is too low, and colorant dissolubility is low.On the impact of hydrolysis of reactive dye, temperature raises, and hydrolysis rate is accelerated, and hydrolysis degree is high.
When dyeing temperature is 30 DEG C, REACTIVE DYES dye-uptake is very low, this is because the cortex construction of viscose is comparatively tight, when 30 DEG C, cortex is not also opened, and fiber cannot be swelling, and REACTIVE DYES can not spread in fiber, so, 30 DEG C time REACTIVE DYES dye-uptake very low.When dyeing temperature is 40 DEG C, the swelling increase of fiber, REACTIVE DYES contaminates, so when dyeing temperature is 40 DEG C, dye-uptake is higher.When dyeing temperature is from 50-80 DEG C, REACTIVE DYES dye-uptake reduces on the contrary, this is because although temperature height viscose is fully swelling, the too high dyestuff of temperature reduces the substantivity of fiber, long at present at high temperature, the ester bond facile hydrolysis of REACTIVE DYES, the easy desorb of dyestuff, equilibrium adsorption capacity declines on the contrary, and dye-uptake declines.
Along with the rising of the dye temperature that begins, the dye-uptake of ACID DYES to polyamide fibre increases gradually, this is because temperature raises, nylon fibre strand intermolecular forces is eliminated gradually, molecule segment is opened, and defines diffusion and absorption that enough holes are beneficial to dye molecule, so the dye-uptake of dyestuff improves.Generally speaking change mixing dye liquor dyeing dyeing temperature in earlier stage to contaminate not as in REACTIVE DYES the impact of ACID DYES.
The present invention finds through large quantifier elimination: in conjunction with homochromatism, soaping fastness and, dye-uptake three considers, draw dyeing early stage temperature be advisable with 40 DEG C.
(6) different temperature retention time
The impact of Discrete control time, is different in different times effect, is mainly manifested in three phases.Early stage dyes temperature retention time (40 DEG C), the upper dye of REACTIVE DYES and the absorption of partially acidic dyestuff.Fixation temperature retention time in early stage (40 DEG C), the fixation of REACTIVE DYES.The change (40 DEG C-100 DEG C) of heating rate.The alkali ACID DYES fixation time (80 DEG C) is added after intensification
The dyeing rate of temperature retention time change major effect two dyestuffs, heating rate change not only affects the dyeing rate of two dyestuffs, also affect the colour fixation rete of REACTIVE DYES, high-temperature holding time is the balance dye-uptake of major effect ACID DYES and the degree of fixation of REACTIVE DYES then.
The present invention finds through large quantifier elimination: and in conjunction with the comparison of homochromatism and soaping fastness, draw the dyeing of technique of the present invention this sticky/bright and beautiful blended ratio the most applicable.
The present invention has the following advantages: described technique is by the research to pH, alkaline agent, electrolyte, color-fixing agent, dyeing temperature in early stage, different temperature retention time, establish mixed dye optimum dyeing technique, make to glue/brocade two kinds of fibers obtain good homochromatism when one-bath process, and obtain higher dye-uptake and soaping fastness.
