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

Entered since 21st century, China's textile industry has obtained rapidly development, but some problems also display gradually simultaneously, as the deficiency of natural resources, energy supply in short supply, to the pollution of ecological environment etc., restricted the development speed and the scale of textile industry, and be on the rise.Energy savings and raw material, reduction consumption, the traditional development model of change are the inevitable requirements of taking a new road to industrialization, implement a scientific outlook on development, realize the strategy of sustainable development, also are the important measures that incorporate globalised economy, strengthen enterprise competitiveness.

Dyeing is the industry of " high energy consumption, maximum discharge ".Electricity, coal, oil, vapour equal energy source consume high in the dyeing process, account for more than 30% of processing cost, 0.86 ton of mark of ten thousand yuan of output value comprehensive energy consumption average out tos coal, exceed more than one times than the average 0.42 ton of mark coal of other industry, water consumption in the dyeing process accounts for about 60% of whole textile industry waters, and wastewater discharge is big, accounts for 60%-70% of printing and dyeing enterprise water consumption, be the 5th of national manufacturing enterprise total emission volumn, be the key industry of national energy-saving and emission-reduction.Reduce the discharging of pollutant, accomplish cleaner production, contamination containment from the source, be not only further promotion textile industry industry restructuring, change the economic development mode, also to the protection environment, building a Harmonious Society is of great immediate significance.

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

During tradition DISPERSE DYES high-temperature pressure dyeing, dye bath is generally carried out under solutions of weak acidity, and 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, hydrolysis can take place in the part DISPERSE DYES, and some the azo structure contained and DISPERSE DYES nitro structure is reduced easily.After these dyestuffs were hydrolyzed or reduce, its color and luster and dyefastness also all changed.Cause that the Another reason that dyestuff decomposes is that DISPERSE DYES has added a large amount of dispersants (NNO, sodium lignin sulfonate etc.) in manufacture process, under 130 ℃ of high temperature, make dye bath be alkalescence.Also because of there being metal ion (Fe in the dye bath ⁺Deng) under high-pressure steam, making basic ionizations such as dye bath reduction and activity hydroxy, water-soluble increase, dye-uptake descend.

Yet the DISPERSE DYES high-temperature pressure dyeing dyes under mild acid conditions and also has a lot of weak points, and the particularly appearance of superfine denier polyester fiber in recent years makes it more outstanding.For example: exist the ring-type linear oligomer below 1.5% in (1) polyster fibre, under acid condition these oligomer to fiber surface shift and with hard water in ca ⁺, Mg ⁺Ions binding forms insoluble condensation product and sticks on the fabric, and then under the effect of mechanical force, part comes off white powderization takes place in dye bath, and oligomer has certain affinity to dyestuff, can produce secondary aggregation and produces and dye defect.(2) fabrics of polyester dyes under mild acid conditions, often makes remaining slurry and finish etc. bring dye bath into because of pre-treatment is insufficient, makes dyeing produce look colored, look dirty phenomenon, affects the raising of dyeing quality.(3) owing to fabrics of polyester is all carried out under alkali condition in the concise and alkali decrement of dyeing pre-treatment, insufficient as the washing after concise and the alkali decrement, dyeing pH value is difficult to control in slightly acidic bath so, causes different, the dyeing repeatability reduction of dyeing coloured light between cylinder and the cylinder.

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

Summary of the invention
