Description

The application of dyeing assistant UNIVADINE SD in the dyeing and finishing of high-count and high-density polyester fabric

Technical field

The application relates to the application of dyeing assistant UNIVADINE SD in the dyeing and finishing of high-count and high-density polyester fabric.

Background technology

Since entering 21st century, China's textile industry obtains and develops rapidly, but simultaneously some problems also display gradually, as in short supply, the pollution etc. to ecological environment of the deficiency of natural resources, energy supply, constrain development speed and the scale of textile industry, and be on the rise.Economize energy and raw material, reduction consumption, change traditional developmental model, be take a new road to industrialization, the inevitable requirement of the strategy of sustainable development of implementing a scientific outlook on development, realize, be also the important measures incorporating globalised economy, strengthen enterprise competitiveness.

Dyeing is the industry of " high energy consumption, maximum discharge ".In dyeing process, electricity, coal, oil, vapour equal energy source consume high, account for more than 30% of processing cost, ten thousand yuan of output value comprehensive energy consumption average out tos, 0.86 ton of mark coal, 0.42 ton mark coal average than other industry exceeds more than one times, water consumption in dyeing process accounts for about 60% of whole textile industry water, and wastewater discharge is large, accounts for 60%-70% of printing and dyeing enterprise water consumption, being the 5th of national manufacturing enterprise total emission volumn, is the key industry that national energy-saving reduces discharging.The discharge of decreasing pollution thing, accomplishes cleaner production, contamination containment from source, be not only promote further textile industry industry restructuring, Economic Development Mode Conversion, also to protection of the environment, building a Harmonious Society is of great immediate significance.

At present, dyeing pre-treatment great majority adopt traditional alkali oxygen technique, in order to ensure product quality, generally adopt destarch, boiling-off technique and improve the pre-treatment processing method of liquid caustic soda, hydrogen peroxide and chemical assistant consumption, process route is long, chemical assistant consumption is large, energy consumption is high, quantity of wastewater effluent is large.

During tradition DISPERSE DYES high-temperature pressure dyeing, dye bath is generally carried out under mildly acidic conditions, this is because most of DISPERSE DYES dye-uptake under mild acid conditions is higher, coloured light is also more stable.If DISPERSE DYES dyes in alkaline bath, part DISPERSE DYES can be hydrolyzed, and some azo structure contained and DISPERSE DYES that is nitro structure is easily reduced.After these dyestuffs are hydrolyzed or reduce, its color and luster and dyefastness also all change.The Another reason causing dyestuff to decompose is that DISPERSE DYES has added a large amount of dispersant (NNO, sodium lignin sulfonate etc.) in the fabrication process, under 130 DEG C of high temperature, makes dye bath be alkalescence.Also because there is metal ion (Fe in dye bath ⁺deng) under high-pressure steam, making the basic ions such as dye bath reduction and activity hydroxy, water-soluble increase, dye-uptake decline.

But DISPERSE DYES high-temperature pressure dyeing dyes and also there is a lot of weak point under mild acid conditions, particularly the appearance of superfine denier polyester fiber in recent years, makes it more to give prominence to.Such as: in (1) polyster fibre, there is the cyclic linear oligomer of less than 1.5%, in acid condition these oligomer to fiber surface transfer and with ca in hard water ⁺, Mg ⁺ions binding forms insoluble condensation product and sticks on fabric, and then under the effect of mechanical force, partial exfoliation, in dye bath, white powder occurs, and oligomer has certain affinity to dyestuff, can produce secondary aggregation and produce dye defect.(2) fabrics of polyester dyes under mild acid conditions, often makes leftover slurry and finish etc. bring dye bath into because pre-treatment is insufficient, and dyeing is produced, and look colored, look dirty phenomenon, affects the raising of dyeing quality.(3) because the concise and Alkali reduction of fabrics of polyester in dyeing pre-treatment carries out all in the basic conditions, as insufficient in the washing after concise and Alkali reduction, the pH value that so dyes in slightly acidic bath is difficult to control, and causes that dyeing colo r light between cylinder from cylinder is different, dyeing repeatability reduces.

And present stage DISPERSE DYES basic dyeing be also one of the high efficiency shortened process, energy-saving and emission-reduction dyeing and finishing technique that dyeing is discussed warmly.Domestic and international many scientific research personnel have carried out a series of research to alkali resistance disperse dye, in succession develop the dyestuff and technique that dye under some are applicable to alkali condition.But corresponding dye species is still little at present, chromatogram is incomplete, and the terylene basic dyeing promoted need adopt special dyeing auxiliary agent to coordinate dyeing, and the performance of dyeing assistant goes back less stable at present.And it is too responsive to pH value at present also to there is dyestuff, easily produce cylinder poor, unstable product quality, can not stablize upper dye in highly basic (as NaOH) system, the dye-uptake of dyestuff is lower than two-bath process, shortcoming that the control of fabric feeling, capillary effect is not good.

Summary of the invention

And UNIVADINE SD synthetic fiber refining-dyeing assistant is applicable to PES, PBT, the synthetic fiber of PTT and PA class and BLENDED FABRIC refining-disperse dyeing single bath process processing thereof have removal impurity (as oil or the knitting oil of spinning, wax etc.), emulsion dispersion leftover slurry and the precipitation preventing oligomer, the effect of crystallization or gathering and dyeing level dyeing, and this auxiliary agent is applicable to the dyeing and finishing processing under acid condition, namely advantage (the favorable reproducibility of DISPERSE DYES acid dyeing is embodied, dye-uptake is high, chromatogram is complete, bright-colored) embody again some advantages (1 of DISPERSE DYES basic dyeing, decrease refinery practice to be conducive to, energy-saving and cost-reducing, reduce discharge of wastewater, enhance productivity.2, a difficult problem for dyeing terylene oligomer is effectively overcome.3, the residual caused look flower of finish, polymer and the slurry that fabric causes because pre-treatment is bad, uneven dyeing, slurry flower is solved.）
