Description
Technical field
The invention belongs to the exhaust dyeing technical field of textiles, relate to a kind of low temperature modification composite active black dye and the application thereof of the fabric dyeing of applicable cellulosic fibre or cellulose.
Background technology
Dyeing is always the industry of highly energy-consuming, high water consumption, high pollution, particularly in recent years, the problem such as the energy, environmental protection more and more causes showing great attention to of country and the whole society, larger pressure is brought to dyeing, in the urgent need to the appearance of reactive monoazo dyestuffs, new auxiliary, novel process, solve or alleviate this many pressure.Current, there is power consumption for the reactive dyestuffs of cellulose dyeing in a large number higher, dyestuff dye uptake is low to be caused producing large amount of sewage, needs to add a large amount of inorganic salt and alkali fixation causes the problems, particularly dark series such as wastewater treatment difficulty, as active black.Active black consumption generally accounts for more than 60% of all colour system dye dosages, and active black ordinary stain depth requirements reaches more than 6%, active black dye consumption so all can be caused large, and waste is also large, effective rate of utilization is low, causes huge social resources waste.
For these problems, many dye manufactures commercial cities are being studied, but be mostly at increase active group, improve dyestuff substantivity to wait to improve dyestuff dye uptake, we are at the new dye structure of exploitation, improve on the basis of dyestuff dye uptake and degree of fixation, according to the Structure and Properties of dyestuff, experimental study is matched dyeing with it, make the utilization ratio of dyestuff reach optimum value, accomplished existing commercially reactive dyestuffs and technique dye less than the degree of depth.By the combination of dyestuff and technique, bring out the best in each other, reach reduction energy consumption, improve dye utilization rate, reduce sewage, the object reduced costs.
Different activities dyestuff has different effects, and in actual production at present, substantially similar to the operation of reactive dyestuffs, and in a lot of actual production, do not pay attention to the operation of different activities dyestuff, a lot of factory still unified a set of technique contaminates nearly all reactive dyestuffs of the same type.The reactive dyestuffs that there be limited evidence currently of people studies different components targetedly need the best staining technique matched with it.This group dye structure of our company, is equipped with the innovative point that the technique be applicable to it is dyestuff development & application technology.
