Description
Technical field
The invention belongs to the light industry technical field, specifically a kind of method of microcapsule disperse dye dyeing.
Technical background
Because DISPERSE DYES solubility in water is minimum, traditional disperse dyeing all is by means of multiple auxiliary agent, compound as dispersant, levelling agent, solubilizer etc., DISPERSE DYES is dispersed in the dyeing medium water as far as possible, and then under conditions such as suitable temperature, pressure, pollutant is implemented dyeing.After dyeing finishes, because the existence of auxiliary agent is stayed in the dyeing waste-water quite a large amount of dyestuffs.Cause and contain a large amount of COD, BOD and serious chroma pollution load in the dyeing waste-water.Residual dyestuff disperses superfine in waste water, and is very stable, so the processing of this type of waste water is very difficult.In printing and dyeing industry, terylene and blending product thereof are accounting for and are cutting off big deal, and they all need to dye and stamp with DISPERSE DYES.Therefore, the amount number of disperse dyeing wastewater is big in printing and dyeing mill's waste water composition, also is unmanageable.The load of environmental pollution also is bigger.
The applicant once invented and applied for name be called ' preparation technology of microcapsule disperse dye ' and ' preparation method of microcapsule disperse dye ' adopt respectively pair or polyisocyanate compound and melamine resin prepolymer and vinyl monomer as the Chinese patent of microcapsule wall material, for the microcapsule dyeing process of free of contamination DISPERSE DYES has been created condition.
Summary of the invention
The purpose of this invention is to provide a kind of colouring method that does not have the microcapsule disperse dye of colourity pollutant effluents.
At above-mentioned existing problem, the inventor studies the successfully staining technique of a cleaning---the microcapsule dyeing process of DISPERSE DYES finally through concentrating on studies for many years.Utilize the present invention, need not auxiliary agent during dyeing, dye bath is formed very simple, only contains the dyestuff capsule in principle in the dye bath.When thick close fabric open width dyeing, a small amount of wetting agent can be added, when thick close fabrics in roped form dyeing, lubricant in a small amount of bath can be added for preventing fabric fold.Microcapsules discharge the unimolecule dyestuff lentamente as the miniature vessel of dyestuff in water, these unimolecule dyestuffs adsorbed by fiber immediately and on dye.This process is performed until dyeing and finishes.After dyeing finishes,, only contain the unimolecule dyestuff of microcapsules and minute quantity in the dye bath because the solubility of DISPERSE DYES is extremely low.Through precipitation or filtration, most residual dyes are separated with microcapsules, and so the dyeing waste-water chroma pollution after the simple process is extremely light, with the naked eye almost can not discover, and has solved the disperse dyeing wastewater pollution problem up hill and dale.
Specifically, the present invention relates to a disperse dyeing technology.Promptly use above-mentioned two or polyisocyanate compound of the inventor or melamine resin prepolymer and vinyl monomer microcapsule disperse dye, dacron is carried out conventional High Temperature High Pressure open width dyeing, High Temperature High Pressure rope dyeing, thermosol dyeing or method such as transfer printing repeatedly as microcapsule wall material.
When High Temperature High Pressure open width or rope dyeing, only contain required microencapsulation dyestuff in the dye liquor, fabric and necessary wetting agent.Can implement in the high temperature-pressure dyeing machine of routine, bath raio should be a bit larger tham the bath raio of normal dyeing, heats up to reach after the predetermined temperature, can keep this condition running, till reaching the predetermined degree of depth on the fabric.With this understanding, textile dyeing degree of depth time to time change can utilize dyeing time to control depth of color, does not have dyeing equilibrium.Can illustrate with following example:
Conventional DISPERSE DYES high-temperature pressure dyeing is generally filled a prescription: commercial dye consumption (including more surfactant): 0.1～3% (heavy to fabric), dispersant: 0～4 grams per liter, bleeding agent: 0～3 milliliter/liter, levelling agent: 0～3 grams per liter, ammonium di-hydrogen phosphate: 1～6 grams per liter, all the other are the water-bath ratio: 1: 30-60.
Microcapsule disperse high-temperature pressure dyeing of the present invention is generally filled a prescription: micro-capsule dyes (not containing surfactant): with respect to the 0.1-5% of fabric weight, bleeding agent: 0～4 milliliter/liter, all the other are the water-bath ratio: 1: 30-60.
High-temperature pressure dyeing carries out in closed container, usually after dye liquor and fabric drop into, keeps this temperature 45-55 minute after being warming up to 120～130 ℃ with 1 ℃/minute speed, cooling, and decompression goes out cloth, discharge opeing.Go out behind the cloth again through reduction cleaning.Microcapsule dyeing in principle can be with same technology dyeing in same machine, and just at high temperature the holding temperature time is slightly long, to reach the dye level of hope.In the occasion of microcapsule dyeing, dye level is controlled with time length basically.Extremely low at colorant dissolubility, when dyeing kinetics is too slow,, can in dye liquor, suitably add a little ethanol in order to quicken dyeing, the water-miscible organic solvent of isopropyl alcohol and so on (solvent intervention effect) with the solubility of raising dyestuff, thereby improves dyeing kinetics.Before dyeing finishes 5-10 minute, by the bypass separator tube on the dyeing container, ethanol or isopropyl alcohol to be separated to reduce the solubility of dyestuff gradually, the dyestuff that dissolves in the assurance dyeing waste-water is minimum.
Thermosol dyeing, traditional DISPERSE DYES thermosol dyeing generally only are suitable for washing/cotton-spinning fabric.Encapsulated DISPERSE DYES then can also be used for pure dacron.But when thermosol dyeing, need suitable water-soluble binder, as sodium alginate etc.General prescription is: micro-capsule dyes: with respect to the 0.1-5% of fabric weight, 1% sodium alginate: the 180-220 grams per liter, bleeding agent higher aliphatic polyoxyethylene ether (JFC): 1～6 grams per liter, all the other are water.
Add water and be transferred to d spiss, make to be suitable for padding.After padding, the microencapsulation dyestuff is attached on fabric, the fiber by means of slurry.Behind 180～220 ℃ of high temperature thermosols processing color developments, flush away capsule and adhesive get final product.The capsule shells and the adhesive that are washed are separated through staticly settling or filtering, and waste liquid becomes clear water.
Repeatedly the printing prescription of transfer printing paper is: micro-capsule dyes: with respect to the 0.1-5% of total slurry amount, the former paste of stamp: all the other are water for the 450-550 grams per liter.
When transfer printing repeatedly, earlier with above-mentioned encapsulated DISPERSE DYES slurry printing transfer paper.Because the at the uniform velocity release performance of capsule, this transfer paper can be used repeatedly, and usually dark transfer printing number of times is few, and light transfer printing as long as control the identical time at a certain temperature, just can obtain the PRINTED FABRIC of same depth color often.Traditional transfer printing in principle can only transfer printing once.Repeatedly transfer printing not only can be saved transfer paper, reduces discarded object, can also improve the rate of using of dyestuff.
The transfer printing temperature is generally 180～220 ℃, and the time is 15-40 second.
The present invention is a kind of colouring method of cleaning.Its advantage is as follows: need not to add dyeing assistant as the traditional dyeing method in (1) dye bath, as dispersant, solubilizer, levelling agent, high temperature levelling agent etc. (these auxiliary agents all are contained in the commercial dye usually), therefore exempted since the dyeing waste-water that auxiliary agent itself causes pollute (BOD, COD); (2) (do not stay in the capsule shells) owing to having these dyeing assistants, residual dyestuff just can not be dispersed in the dye liquor, so the dyeing waste-water chroma pollution is extremely light.(3) processing of dyeing waste-water is very convenient, as long as simply staticly settled 2-3 hour or simple filtering just can separate residual ground dyestuff and capsule in the dyeing waste-water easily.(4) dyeing (prescription) is simple, but the high temperature levelling agent of conserve expensive and other auxiliary agents.(5) dyeing waste-water can reuse or can be reached zero colourity discharging, has thoroughly solved the difficult problem that disperse dyeing wastewater is for many years handled.
