Abstract

The invention discloses an accelerant of active dye, which comprises the following components: the sodium salt and the potassium salt of amino acid. The invention adopts the salt of amino acid and common salt to promote the dyeing of the active dye, can significantly improve the degree of fixation of the active dye, does not need to transform the dyeing equipment of the traditional active dye or change the dyeing technical parameters of various active dye, is good for reducing the used amount of the accelerant so as to improve the environmental protection effect, reduce the production cost, and realize environmental-friendly and low-salt active dyeing.

Description

A kind of accelerant of REACTIVE DYES

Technical field

The present invention relates to a kind of accelerant of REACTIVE DYES.

Background technology

Reactive dyestuff molecule is simple in structure, lovely luster, and chromatogram is complete, and is easy to use, with low cost, and fastness is good, and has high security, is widely used.Yet, in traditional dyeing, in order to improve dye fixing rate and degree of fixation, need to add that a large amount of inorganic salts are short dyes, different according to the structure of dyestuff and DYED FABRICS character, the amount ranges of salt is about 30～150g/L.The adding of a large amount of neutral salt makes dyeing waste water cause serious environmental to pollute.The discharge of wastewater of high salinity has directly changed the water quality in rivers and lakes, has destroyed ecological environment.The high osmosis of salinity will cause the soil property salinization of soil around river, the lake, seriously cause the soil forfeiture and cultivate ability.Given this, external many companies are devoted to development of new low-salt active dyestuff, the CibacronLS type REACTIVE DYES of Ciba company, and the inorganic salts consumption is 1/2 to 1/3 of a general double-active radical dye, but large-scale application low-salt active dyestuff also has very long road.Although replacing inorganic salts with organic reagent is present research focuses, as the used additives modified cotton fabric, the salt-free dyeing of research REACTIVE DYES is because problems such as security and technology still are in research state.There is the researcher to study organic salt EDTA abroad and does accelerant, effect is preferably arranged, but the difficult control of dyeing.External report dyes as accelerant with natrium citricum, has the preferable short effect of dying, and is biodegradable, environmentally friendly, but it costs an arm and a leg.Domestic report carries out the composite consumption that can reduce inorganic salts with salt, but the consumption of salt is still higher, and cost is also higher relatively.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of accelerant of REACTIVE DYES, by adding the consumption that this accelerant can significantly reduce inorganic salts, helps protecting environment and reduces production costs the dyeing of realization environmental protection low-salt active.

In order to solve the problems of the technologies described above, the accelerant of a kind of REACTIVE DYES of the present invention, the component of described accelerant includes amino-acid salt.

As improvement of the technical scheme, described amino-acid salt is amino acid whose sodium salt or sylvite.

As further improvement in the technical proposal, described amino-acid salt is amino acid commonly used, the sodium salt of tryptophan, methionine, threonine, valine, lysine, histidine, leucine, isoleucine, alanine, phenylalanine, cystine, cysteine, arginine, glycine, serine, tyrosine, 3.5. diiodotyrosine, glutamic acid, asparatate, proline, hydroxyproline, arginine, citrulling, ornithine etc. and the one or more kinds of combinations in the sylvite.

The invention has the beneficial effects as follows: the present invention adopts amino acid whose sodium salt or sylvite, accelerant as inorganic salts, can obviously reduce the consumption of inorganic salts, and need not to transform conventional reactive dyeing equipment, and the staining technique parameter of various REACTIVE DYES need not to change, help reducing the consumption of accelerant, thereby promote environment protecting and reduce production costs the dyeing of realization environmental protection low-salt active.

The specific embodiment

The accelerant of a kind of REACTIVE DYES of the present invention, the component of described accelerant includes amino-acid salt, and described amino-acid salt is amino acid whose sodium salt or sylvite.

Described amino-acid salt is the sodium salt of tryptophan, methionine, threonine, valine, lysine, histidine, leucine, isoleucine, alanine, phenylalanine, cystine, cysteine, arginine, glycine, serine, tyrosine, 3.5. diiodotyrosine, glutamic acid, asparatate, proline, hydroxyproline, arginine, citrulling, ornithine etc. and the one or more kinds of combinations in the sylvite.

The consumption of described accelerant only is 0.1 ~ 0.5g/L.

The present invention adopts the minute quantity amino-acid salt to urge to dye reactive dyeing with neutral inorganic, need not to transform conventional reactive dyeing equipment, and the staining technique parameter of various REACTIVE DYES need not to change, help reducing the consumption of accelerant, thereby promote environment protecting and reduce production costs the dyeing of realization environmental protection low-salt active.
