Description
Technical field
The present invention relates to a kind of preparation methods of environment-friendly high-intensity liquid disperse dyes, belong to printing technology field.
Background technique
In recent years, as environmental problem is got worse, country is higher and higher to the requirement in terms of environmental protection, to textile printing and dyeing row
The regulation of industry is also increasingly stringenter, and there is an urgent need to the high-intensitive dyestuffs of energy-saving and emission-reduction for textile printing and dyeing enterprises.
Liquid dyes are to develop to process dosage form than faster dyestuff in recent years, since it is easy with production method, uses
The advantages that dyeability can be improved in easy to operate, energy-saving and emission-reduction, and by the great attention of printing and dyeing mill, development speed is very fast.
Liquid dyes are prepared with following features: 1, liquid dyes do not need the process such as dry, granulation, molding, therefore
Process equipment greatly simplifies, and production process is obviously shortened；2, the storage stability of liquid dyes is poor, is easy to produce precipitating, because
This requires reasonable selection dispersant with high efficiency and other matched addition auxiliary agents, more needs to the formulating of commodity, preparation process
It keeps on improving；3, it needs using advanced microemulsified, pulverize dispersion suspended substance processing technology, for water-insoluble dye
Material, can also produce and process stable liquid dyes dispersion by wet type superfine communication technique；4, it is particularly suitable for dispersion dye
The production and processing of material reduces impurity so that disperse dyes be made further to be purified processing, improves purity.
Liquid disperse dyes have following items basic demand: 1, the dispersion of liquid should be more stable, can be in longer-term
Time lower storage；2, there is good mobility, pump conveying can be used, can toppled over；3, it is easy at normal temperature or in cold water
It disperses or dissolves, it can or blending miscible with similar or other dyestuffs；4, noxious material is free of, PH is neutrality；5, it should mention as far as possible
High dye strength；6, a variety of dyeing and printing process are applicable to.
The advantages of liquid disperse dyes: 1, good application performance uses always powder in printing and dyeing industry for a long time
Shape, granular dyes, when sizing mixing or preparing dye liquor, dyestuff dust is most troubling problem, not only influences environment, hinders labor
Dynamic protection, and be often attached on the apparatus of ingredient or suspend in the dye liquor foam of preparation.Big not be dispersed or dissolved
The grain dyestuff that dyestuff, especially solubility are small, dispersion performance is poor, wettability and dispersion performance are all poor, are easy mutually to cohere
At agglomerate, it is easy that fabric is made to form fault in dyeing, influences product quality.And the above problem is substantially not present in liquid dyes,
The generation of dyeing defect can be significantly reduced.2, migration phenomenon is reduced, the migration of dyestuff is a problem deserving of attention, dyestuff
Migration degree is related with perhaps various factors.It is again mainly related with the content of auxiliary agent in dyestuff.It is related studies have shown that many points
Powder, wetting agent have the tendency that increasing dyestuff occurs migration.In liquid dyes processing formula, due to dispersing agent dosage compared with
Solid fraction dyestuff substantially reduce (as soon as correspond generally to liquid dyes five/or less), so also effectively reducing dyeing
Migration degree when post-process treatment；3, dye-uptake can be improved, some non-water soluble dyes, especially disperse dyes are washed in dye
When synthetic fibre or other synthetic fibers, grain fineness is important.Usual powdery, granular dyes are needed after being pulverized by drying process,
This just inevitably makes partial particulate generate cohesion, dispersion performance decline.Therefore, solid fraction dyestuff is thick compared with the particle of liquid dyes
Greatly, same amount of powder dye and liquid dyes hot melt dye terylene, as a result, upper dye of the liquid dyes than powder dye
Rate is high, and maximum differential can reach 50% or more sometimes.And hot melt when dyeing powder dye be also easy to produce fault, and liquid dyes
It but can be to avoid such problems；4, liquid dyes reduce production cost, and liquid dyes compare with solid fraction dyestuff, do not need drying
Process, also do not need dry grinding and dry blending process: this just substantially reduces the technological process of production.Drying is one in production
Highly energy-consuming operating process eliminates drying and just saves production cost, in addition, with water instead of part of auxiliary in liquid dyes
Use, largely also reduce cost of material, thus liquid dyes can be effectively reduced dyestuff cost of material and
Production cost；5, the COD in dyeing residual liquid is reduced, the dye dispersant as used in liquid dyes and other auxiliary agents are relatively
Few, allowing for COD content in dyeing residual liquid naturally reduces；6, the coloration for reducing dyeing residual liquid, due to liquid dyes dye uptake
Higher than powder dye, dyestuff remaining in raffinate is less after dyeing, and the coloration of raffinate is substantially reduced；7, with present labour city
The increased costs of field, more and more printing and dyeing enterprises have used automation process equipment, and liquid disperse dyes are particularly suitable for automatic
Change metering, obtains a large amount of application therewith.
The former dyestuff weight percent control range of liquid disperse dyes on existing market is 17.9%~36%, auxiliary agent
Weight percent control range is 4.5%~14.4%, auxiliary agent and former dyestuff weight percent control range are 0.25~0.4:
1, there are liquid dyes low strength, in application, there are a little limitations for printing and dyeing mill, and auxiliary agent content is higher, the color of raffinate after dyeing
Degree abs value, COD are higher, and there are no the purposes for really realizing optimal energy-saving and emission-reduction.
Summary of the invention
The technical problems to be solved by the invention: steady for the liquid disperse dyes low strength on existing market, storage
