The method comprises the following steps: (1) preparing a dye solution; (2) dyeing; (3) preparing a washing solution; (4) washing; (5) post-processing; (6) stentering; (7) pre-shrinking; and (8) inspecting cloth and rolling. Through the method for dyeing the terylene textile, the dispersing performance of the disperse dye can be greatly improved; the utilization rate of the dye and the dye uptake of fibers are increased; the dyeing defects of uneven dyeing, colour spots, streakiness and the like are avoided. Meanwhile, through the method, the dyeing difficulty can be reduced, and the dyeing effect and the dyeing quality can be improved. Alcohol organic solvents used in the method are safe, non-toxic and easy to recycle, so that the usage amount of water in the dyeing process is greatly reduced, and the discharge of waste liquid is reduced; the method is safe and clean and has energy-saving and environmental-friendly effects.
Description
Technical field
The present invention relates to a kind of method of Polyester Textiles dyeing.
Background technology
The method of conventional polyester dyeing is to carry out in higher than the airtight dyeing installation of 100 ℃ in temperature, belongs to a kind of damp and hot colouring method.This method is normally carried out in water, on the one hand, the factors such as quality of programming rate and use DISPERSE DYES performance during due to dyeing machinery performance, dyeing, can make the dispersive property of dyestuff decline, dyestuff produces secondary aggregation or makes to dye thing because the compatibility of dyestuff is poor and causes look flower, color spot, barriness etc. to dye defect, affects quality.On the other hand, owing to needing to consume a large amount of water resources in whole dyeing engineering, make seriously polluted to environment of dyeing, the waste water after dyeing reclaims difficulty, and cost is higher.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of method of Polyester Textiles dyeing.
The method of described a kind of Polyester Textiles dyeing, is characterized in that comprising the following steps:
1) dye liquor preparation: DISPERSE DYES, dispersant and sour buffer are placed in to the mixed liquor of alcohol organic solvent and water, are mixed with dye liquor after stirring;
2) dyeing: dye liquor and Polyester Textiles are placed in to dyeing machine, then dye liquor are warming up to 120-130 ℃ with the speed of 1-2 ℃/min, dyeing time is 25-35 minute;
3) cleaning solution preparation: soap flakes and sodium carbonate are placed in to the mixed liquor of alcohol organic solvent and water, are mixed with cleaning solution after stirring;
4) washing: the Polyester Textiles after dyeing is put into cleaning solution and wash, wash temperature is 95 ℃, and wash time is 10 minutes;
5) post processing: the Polyester Textiles after washing is dried, and bake out temperature is 80 ℃;
6) tentering: the Polyester Textiles after post processing is put into stenter and carry out tentering, the humidity in stenter is not more than 6%;
7) preshrunk: the Polyester Textiles after tentering is put into preshrinking machine and carry out preshrunk;
8) cloth-inspecting rolling: shape and check Polyester Textiles, by testing the clot of volume combination machine.
The method of described a kind of Polyester Textiles dyeing, the bath raio that it is characterized in that dye liquor in described dye liquor preparation is 1:30-1:60, the volume ratio of alcohol organic solvent and water is 95-50%:5%-50%, the concentration of DISPERSE DYES is Polyester Textiles quality 1%-5%, the concentration of dispersant is 0.5-2g/L, and the concentration of sour buffer is 1-3g/L.
The method of described a kind of Polyester Textiles dyeing, the bath raio that it is characterized in that cleaning solution in described cleaning solution preparation is 1:25-1:35, the volume ratio of alcohol organic solvent and water is 95-50%:5%-50%, and the concentration of soap flakes is 1-3g/L, and the concentration of sodium carbonate is 1-3g/L.
The method of described a kind of Polyester Textiles dyeing, is characterized in that described Polyester Textiles is a kind of in Polyester fibre or spun polyester thread or Woven Polyester Fabrics or polyester knitting thing.
The method of described a kind of Polyester Textiles dyeing, is characterized in that described alcohol organic solvent is a kind of in ethanol or isopropyl alcohol.
The method of described a kind of Polyester Textiles dyeing, is characterized in that described alcohol organic solvent is a kind of in ethanol or isopropyl alcohol.
The method of described a kind of Polyester Textiles dyeing, is characterized in that described sour buffer is a kind of in sodium acetate or ammonium dihydrogen phosphate (ADP) or ammonium sulfate.
The present invention adopts the method that changes dye liquor and cleaning solution configuration in Polyester Textiles dyeing, by the dye liquor that alcohol organic solvent and a small amount of water and DISPERSE DYES mix is at high proportion dyeed to Polyester Textiles, and with the cleaning solution that alcohol organic solvent and a small amount of water mix, the Polyester Textiles after dyeing is washed.Because the molecular proportion water of alcohol organic solvent is large, so when temperature is during higher than the vitrification point of terylene, alcohol organic solvent can make the hole that holds dye molecule that the strand activity of terylene amorphous region produces increase, like this, the dyestuff being dissolved in dye liquor will enter people's terylene, and the dyestuff on terylene surface can dye with molecular forms in fibrous inside diffusion.Now, dyestuff also Yin Wendu raises and acceleration molecular motion, becomes dissolved form or solubilization state, and spread to fiber amorphous region from dispersity, until dyestuff is by fibers adsorption and dyestuff, desorb speed from fiber reaches equal, and dyeing reaches balance and just completes dyeing course.The effect of in alcohol organic solvent, dyestuff being played due to dispersant, make the DISPERSE DYES in alcohol organic solvent by crystal grain dissolving, be unimolecule and be gathered in fiber surface under the effect of dispersant, dyestuff unimolecule is got over miniaturization, and the level dyeing degree of dyeing is just better.Dispersant in dye molecule can form one deck interfacial film at fiber surface, makes the dye molecule that is attached to fiber surface progressively diffuse into fibrous inside, thereby can be good at avoiding the phenomenons such as look flower that cause owing to dying in wink, thereby has improved Color.Adding of alcohol organic solvent declines dye liquor surface tension, dyeing terylene difficulty reduces, alcohol organic solvent also makes the water yield in dyeing and washing process reduce greatly, and alcohol organic solvent is nontoxic, can realize the enclosed circulation dyeing of terylene, the alcohol organic solvent after dyeing can also be passed through recovery system recycle and reuse.Therefore, the invention solves in traditional Polyester Textiles dye process dyeing difficulty and level-dyeing property is poor and water consumption is large and with serious pollution problem.
The method of dyeing terylene of the present invention, can either improve the dispersive property of DISPERSE DYES preferably, increases utilization rate and the dye-uptake to fiber of dyestuff, avoid look flower, color spot, barriness etc. to dye defect, can reduce dyeing difficulty again, improve Color, improve dyeing quality simultaneously.The alcohol organic solvent safety non-toxic that method of the present invention adopts and be easy to recycle and reuse, not only greatly reduces the consumption of water in dyeing course, and has reduced the discharge of waste liquid, energy-saving safe, clean environment firendly.
