Description
Technical field
The present invention relates to a kind of methods for improving polyester knitting object carrier dyeing liquid stability, belong to textile printing and dyeing technology neck
Domain.
Background technique
Terylene is the stronger fiber of hydrophobicity and inner molecular structure arrangement is closer, and crystallinity is high, Ying Caiyong when dyeing
With the comparable dyestuff of its hydrophobicity.Disperse dyes be it is a kind of water-soluble it is very low, molecule is smaller, structure is simple, when dyeing in water
Mainly with subparticle in non-ionic dye existing for dispersity.Generally there are following three kinds of shapes in dye bath for disperse dyes
State: it a small amount of unimolecule dyestuff for being dissolved in dye bath, the disperse dyes being present in dispersing agent micella and is suspended in dye bath
Disperse dyes granule.When dyeing, disperse dyes granule directly upper cannot contaminate polyester fiber, the dye molecule being only dissolved in water
It is contaminated in ability.
Disperse dyes are difficult to enter fibrous inside under normal conditions, how to accelerate that dyestuff suction is contaminated and improved on disperse dyes
Attached amount is always a vital task of dyeing terylene.For polyester knitting object, high-temperature pressure dyeing is mainly used at present
Method is dyed, when it is fiber-heated to more than glass transition temperature when, fiber macromolecular chain segment motion intense, intermolecular gap increases
Greatly, dye molecule can enter fibrous inside, and dyeing rate will be obviously improved.High-temperature pressure dyeing can obtain level-dyeing property and thoroughly dye
Property good product, applicable dye species are also more, and dye utilization rate is high, but the high requirements on the equipment, dyeing time are long, production effect
Rate is low.Under high temperature, dyestuff dispersion stabilization can be reduced, and dye granule is easy to condense into coarse particle or the suction of coking oily drop
It is attached to fabric surface and generates color dot, cause dyeing defect.
Polyester knitting object another kind colouring method is carrier dyeing process, that is, selects certain carriers to make auxiliary agent, make disperse dyes
The method that terylene can be contaminated in 100 DEG C of conditions below of normal pressure.Common carrier is usually the simple aromatic series of some structures
Organic compound, such as aromatic phenols, esters, alcohols, ketone, hydro carbons.Their water solubility is not general high, and when use needs
Emulsion or dispersion liquid to be made in advance.But common carrier is added in dyeing terylene liquid and easily causes dye liquor dispersion stabilization
Decline, dyestuff are easily assembled and generate dye defect.
Many biology natural high molecular substances such as albumen, DNA etc. have certain stably dispersing to act on.Weaving
With having the independence separated hydrophobic in cellulase structure and hydrophilic region, unique colloid property is shown, it can be to many objects
Matter generates certain stably dispersing effect.In addition, cellulase is only related with its spatial configuration of molecules to the dispersibility of hydrophobic substance,
It is not relevant with catalytic activity, therefore deactivated discarded enzyme can be used, this is also a big advantage.
Cellulase is mainly used for polishing pure cotton fabric etc., generally in reel dye machine, spraying machine, rotating cage type water
It is carried out in the equipment such as washing machine.In cellulase polishing treatment process, portion of cellulose enzyme molecule is adsorbed to fabric surface, remaining
Then remain in treatment fluid, it is discharged with treatment fluid after inactivation treatment.
Summary of the invention
The present invention carries out disperse dyes carrier dyeing to polyester knitting object using cellulase biopolishing waste water, not only real
The recycling of existing waste water, and effectively improve by the effect for remaining in waste water cellulase carrier is added after disperse dyes
Stability in dye bath mitigates dye defect phenomenon.
The present invention includes following technique:
(1) after the completion of the processing of conventional fibre element enzyme biopolishing, treatment fluid pH is adjusted to 8, is warming up to 110 DEG C of processing 15min, it is cold
But it filters afterwards；
(2) the disperse dyeing carrier of conventional amount used is added in treatment fluid, is thoroughly mixed uniformly；
(3) treatment fluid pH is adjusted to 5.5, disperse dyes is added, conventional carrier dyeing and subsequent processing is carried out to polyester knitting object.
After the completion of standard biologic polishing treatment, treatment fluid pH is adjusted to 8,110 DEG C of processing 15min are warming up to, in alkali and height
The space structure of cellulase, molecular structure, physicochemical properties etc. will adjust under the action of temperature.It can by treatment fluid filtering
Remove the unstable product from the larger impurity and treatment process that textile surface falls off.Then, conventional in treatment fluid
The dyeing carrier of dosage is thoroughly mixed uniformly.Finally, treatment fluid pH is adjusted to 5.5, disperse dyes are added to polyester knitting
Object carries out conventional carrier dyeing and subsequent processing.In dyeing course, treated Cellulase Molecules will generate carrier
Protective effect mitigates its adverse effect to disperse dyes dyebath stability.
