In January, an annual output of 1,000 tons of FL series containing fluorine reactive dyes, 3,000 tons of low-temperature reactive dyestuff production line in hubei province SongZiShi beautiful source (hubei) technology Co., LTD formally put into production. The company is working on the second phase of 20,000 tons capacity expansion project, including modification 3,000 tons/year FL series, 1000 tons/year 80 ℃ low-temperature wool special dye, 1000 tons/year brocade one bath dye, 5000 tons/year exemption reductive cleaning dispersal dyes, 1000 tons/year containing fluorine normal temperature transfer printing dye and clean process of matching production related materials, etc, but also will be built project 1000 tons/year hydrophilic silicone oil production capacity. The second phase of the project is completed, li source (hubei province) technology Co., LTD. Every year, 40,000 tons of textile chemicals production, there will be more than 50% energy saving and emission reduction effect is significant environmental protecting dye.

The chairman of the company LuoRunFu when interviewed emphasize, li source technology Co., LTD. In product positioning on national "1025 planning tncsted and focus on the requirements of" in energy conservation and emission reduction environment-friendly textile dye development fuss.

Why development containing fluorine reactive dye

Reactive dyes by market is the most popular cellulose dye, because it is replacing disable dyes and other types of cellulose with dyes, and the best choice of economic dyeing and use simple dyeing operating a high level of various coptidis thizoma, especially wet good fastness. Reactive dye with chromatographic wide, bright color, excellent performance, strong applicability, its hue and performance of the fibers and with market basically to adapt the request cloth etc.

Now the world reactive dyes production has been accounted for dye 20% ~ 30% of the total, ranked the first with dyes cellulose. But ordinary reactive dyes utilization rate is not high, utilization rate is hardnut problem commonly in 60 ~ 65%, and extensive use of intermittent devoured dyeing in after dyeing processing time is longer, including flushing, neutralization, washing, soaping, washing and solid color waiting time to total dyeing time 1/3. Existing process not only time-consuming, high energy consumption, waste, and to generate a lot more difficult to treat non-ferrous salt-containing sewage, still doesn't wash except the final fixation of the hydrolysis of dyes and in turn affect dyeing fastness properties so that reactive dyes is currently dyeing and printing industry application of dyes in energy consumption and pollution of the dye one.

Our country used annually to about 10 million tons of reactive dyes, experts estimate that if all change to use containing fluorine reactive dyes or similar reactive dyes, every year may be less row about 4,500 tons of printing and dyeing wastewater, reduce the inorganic salts usage 3.25 million tons ~ 45 million tons.

But, containing fluorine series dye high requirement of technology, in li yuan company FL series active dyes to market before, global only dystar in Germany, huntsman and clariant in Basel, Switzerland has manufactory, li source of FL series dye once into the market, is relying on the stable quality, partial variety price is only 50% of imposing high price advantage caused YinRanYe attention.

Containing fluorine series activity of dye characteristics

Li source technology and wuhan textile university established joint laboratory, through researching developed containing fluorine reactive dyes FL series, this is a kind of contains a fluoride are three work base and the beta hydroxyl sulphone sulfuric acid ester base of double active dyes.

From the chemical on look, generally fluorine electricity negative than replaced by chlorine, chlorine, nuclear fluorine carbon atoms on the probability density decreased, make the reactive dyes plane better. Two active groups with aliphatic foundation coupling, maternal dye molecules is lesser, have low to moderate affinity, adopted aliphatic solvent.it ethyl sulphone and fluorine three work, make the connection of electrical amino nitrogen atoms negative abate the base of sulfuric acid ester PSF sulfuric acid ester, therefore the influence of relatively stable in lye seldom happened beta elimination reactions and peels, in in lye more stable. Such molecular structure contains a fluoride are three work and ethylene sulphone base, reactive strong, fixation ratio 80%, at the same time as fluorine three work activity and ethylene sulphone close, dyeing of sodium, sodium carbonate, bath ratio, temperature dependence small time etc.

This project 2010 passed by hubei sta advanced scientific and technological achievements appraisal and won the 2010 hubei science and technology progress prize, and included the Chinese dyeing and printing industry association of energy saving and emission reduction advanced technologies recommended directory.

At present, this series product still through Swiss textiles verification Co., LTD Oeko Stand100 ecological authentication and the Dutch league GOTS ecological regulation authentication. Obtained open foreign high-end reactive dye market pass.
