Description
Technical field
The present invention relates to a kind of dyeing method, particularly a kind of cotton fabric by utilizing reactive dye printing method of banking up.
Background technology
REACTIVE DYES is also referred to as chemically-reactive dyes, it is with one or more active group in dye molecule, it is reactive group, under certain condition, can with cellulose fibre on hydroxyl and azelon, polyamide fiber on amino etc. there is bonding reaction, between dyestuff and fiber, form the dye of covalent bond.
Reactive dyestuff molecule is simple in structure, lovely luster, and chromatogram is more complete, easy to use, and cost is lower, contains sulfonic group aqueous solution group, is ionized into dyestuff anion in water, and hard water is had to higher stability, and diffusivity and level-dyeing property are better.But it is low that REACTIVE DYES remains at degree of fixation, need the problems such as high salt dyeing and high concentration urea stamp.In addition, the reactive dyeing time is longer, and the consumption of dyestuff and chemicals is large, adds a large amount of neutral electrolytes to urge to dye during dyeing, unfavorable to environmental protection.
COTTON FABRIC is weaved and is formed by native cellulose fibre, has good hygroscopicity, flexibility, feel, parent's clothes property, is the particularly major product of underwear fabric of garment material.The stamp of COTTON FABRIC adopts screen cloth technique conventionally, and because REACTIVE DYES chromatogram number is wide, wet colour fastness is better, and stamp cost is low, and it is convenient to print, and uniformity is good, so the REACTIVE DYES direct printing the most frequently used printing method that is COTTON FABRIC.At present cotton fabric by utilizing reactive dye printed fabric application is very extensive, and the market demand is large, and no matter clothes, bedding, ornament materials all can be seen printing with reactive dye cotton.But in traditional Reactive Printing Process, stamp post processing adopts gas steaming and bakes two kinds of modes carries out fixation treatment, there is the problem of high water consumption, highly energy-consuming in this technique therefore.
Summary of the invention
The invention provides a kind of cotton fabric by utilizing reactive dye printing method of banking up.Employing adopts the mode of cold dome to carry out fixation treatment after stamp, and its fixation firmness is high, water consumption is low, energy consumption is low.
According to an aspect of the present invention, provide the cotton fabric by utilizing reactive dye printing method of banking up, comprised the following steps:
(1) REACTIVE DYES that is 1%-3% by percentage by weight, the urea of 2%-6%, the thickener of 15%-20%, the alkaline agent of 1%-5% add water to 100% and are mixed with mill base;
(2) with the mill base preparing in step (1), COTTON FABRIC is carried out to stamp;
(3) COTTON FABRIC after stamp is banked up fixation;
(4) after being washed, soap, washed, the good COTTON FABRIC of fixation dries.
In some embodiments, in step (1), by weight percentage, REACTIVE DYES consumption is 2.0%～2.5%, alkaline agent consumption is 3.0%～4.0%.
In some embodiments, in step (1), by weight percentage, REACTIVE DYES consumption is 2%, the consumption of alkaline agent is 3%, the consumption of urea is 4%.
In some embodiments, the temperature of banking up in step (3) is 25 ℃～35 ℃.
In some embodiments, the temperature of banking up in step (3) is 30 ℃.
In some embodiments, in step (3), the time of banking up is 6～10 hours.
In some embodiments, in step (3), the time of banking up is 8 hours.
In some embodiments, the thickener in step (1) is sodium alginate, carboxymethyl starch or carboxymethyl cellulose.
In some embodiments, the alkaline agent in step (1) is sodium carbonate or sodium bicarbonate.
In some embodiments, the mill base in step (1) also comprises that percentage by weight is 2% calgon.
The bank up mill base of printing method stamp of cotton fabric by utilizing reactive dye of the present invention is comprised of REACTIVE DYES, thickener (being former paste), auxiliary agent, alkaline agent.The selection that stick with paste in its Central Plains has a great impact printing quality, and printing with reactive dye often selects sodium alginate as thickener.In the structure of sodium alginate, with carboxylic acid group (-COOH), in alkaline medium, generate carboxylic acid and receive (-COONa), be dissolved in the water, be ionized into carboxylate anion and sodium ion, therefore sodium alginate is cloudy lotus property, has good compatibility with the REACTIVE DYES of cloudy lotus property, and Dry Sack rate is higher.The effect reason of carboxymethyl starch or carboxymethyl cellulose is identical with sodium alginate.Auxiliary agent mainly contains urea and calgon.Urea add the dissolving that is conducive to dyestuff, improve the dissolubility of dyestuff, and be good hygroscopic agent, swelling agent, make dye well auxiliary agent after fully dissolving, can permeate rapidly and be combined with cellulose fibre, improve the fixation rate of dyestuff.Sodium alginate is the calcium binding easily and in water and generate calcium alginate (COO) during fabrication
2ca precipitation, calcium alginate (COO)
2ca sediment makes the carboxylic ions-COO-in sodium alginate structural formula lose the electric charge of cloudy lotus property, not only the REACTIVE DYES with cloudy lotus property is not had to repulsive interaction, and make the inferior hydroxyl (CHOH) in sodium alginate structural formula likely produce color dot with some REACTIVE DYES generation bonding, and make printing gum be difficult for washing to the greatest extent and generation staining.So both damage the performance of mill base, also affected dyefastness simultaneously.Therefore when hardness of water is larger, must add calgon to prevent from generating calcium alginate.
It is painted that the present invention adopts REACTIVE DYES, under alkaline environment, COTTON FABRIC is carried out to stamp, then the fixation of banking up at low temperatures, wherein the influential factor of printing quality tool also had to the following aspects:
(1) impact of dye dosage
Tradition stamp is different from dyeing, REACTIVE DYES exhaust dye in process, have sufficient suction look, fixation time, but traditional thickening agent and fiber are shorter contact time.And for the fixation of banking up after stamp, contact time is basic identical with dyeing, the concentration requirement of dyestuff is also similar.The concentration of dyestuff can exert an influence to the diffusion rate of dyestuff, and higher its diffusion rate of concentration is also just faster, and level dyeing, through-dyeing are just better.But, if excessive concentration can make REACTIVE DYES dissolve in mill base and produce difficulty, and can cause level-dyeing property to decline, color depth reduces.
(2) impact of urea
Urea plays a part more important in REACTIVE DYES direct printing.Urea add the dissolving that is conducive to dyestuff, improve the dissolubility of dyestuff, urea or good hygroscopic agent, in fixation process, can fully absorb moisture around, thereby be conducive to the dissolving of dyestuff and other auxiliary agents, while urea or the swelling agent of cellulose fibre, make dye well auxiliary agent after fully dissolving, energy rapid permeability is also combined with cellulose fibre, on raising dyestuff, dyes quantity.
(3) impact of alkaline agent
Adding of alkaline agent, in printing with reactive dye process, play the effect of fixation.After alkaline agent adds, make the PH of mill base be adjusted to alkalescence, in fixation process, can promote active group and fiber to react, form stable covalent bond, dyeing rate and color depth are all improved.But pH value can not be too high, add the intensity of alkaline agent and the consumption can not be excessive, otherwise can impel the hydrolysis of fiber, COTTON FABRIC is brought to damage, also can accelerate the hydrolysis of dyestuff simultaneously, can weaken on the contrary dyestuff on dye and fixation.
(4) impact of color fixing temperature
Temperature is larger on the fixation impact of REACTIVE DYES.Temperature raises 10 ℃, and reaction speed can improve 2～3 times.But excess Temperature also can make the hydrolysis rate of dyestuff accelerate, become key fixation quantity to reduce.Therefore in actual production, must select suitable dyeing temperature, it be reacted completely in official hour, to obtain higher color depth.The dyestuff high to reactivity, color fixing temperature is lower, reactive low dyestuff, color fixing temperature is higher.
(5) impact of fixation time
After stamp, the time of fixation can not be long, and reason is that REACTIVE DYES under alkaline agent effect, fixation occurs with fiber and reacts, and also hydrolysis to a certain degree can occur simultaneously.In fixation early stage, dyestuff becomes key fixation to react to occupy an leading position with fibrogenic, and color depth constantly increases, until maximum; After fixation reaction completes substantially, continue to extend and banks up the time, it is more and more that on fiber, the amount of hydrolysis scission of link occurs the dyestuff of combination, becomes key degree of fixation to start to decline, so that the fixation time of banking up of mercerized cotton fabric is wanted is relatively shorter.
The invention has the beneficial effects as follows:
(1) energy resource consumption is low.Think comparison with traditional printing technology, the overall consumption of water, electricity and gas reduces by 20%～30%.
(2) environmental pollution is little.In the present invention, electrolyte consumption is few, and dye utilization rate is high, and sewage discharge is few.
(3) equipment investment is few, and capital cost is low, strong adaptability.
(4) dyefastness is high.
(5) superior permeability of dyestuff, even dyeing.
(6) simple, the good product quality of technique, the mode of production are flexible.
