Background technology
Reactive dyestuffs with bright in colour, chromatogram is complete, applications is easy, with low cost, fastness is good celebrated.Reactive dyestuffs have become the painted most important dye class of cellulose fiber textile.
The development research of Yellow active dye is one of focus of dye industry concern always.
Use in the current Yellow active dye and represent kind to be C.I.Reactive Yellow 145 widely.
Its structural formula is:
This dyestuff has better dyefastness, but also has certain defective, and for example relative dye level, enhancing and level-dyeing property are difficult to satisfy the requirement of current printing and dyeing.The U.S. Pat 5,484 that Ciba-Ceigy company delivers, 899 (1996) have announced the Yellow active dye that a kind of following general formula is represented, and it is with 2, and the 4-diamino benzene sulfonic acid is that coupling component makes.
It is golden yellow that this reactive dyeing is, and all fastness are all good.

In addition, CN 1569969A (2005) (Shen, Jiangsu is new) has disclosed a kind of reactive yellow SHE dyestuff.The structural formula of this reactive yellow SHE dyestuff is:
Dyestuff X
The inventor thinks that behind the dyestuff of the above-mentioned two kinds of structures of concentrated research introduce 2 in dye structure, 4-diamino benzene sulfonic acid molecule truly has the effect of improving performance.But this class dyestuff remains in the requirement of satisfying current tint applications in some deficiency, for example dye fixing rate, dye uptake, level-dyeing property and all remain further to be improved with the consistency of other dyestuff when dying.
During the last century the nineties, the Japanese Patent that Hoechst company delivers (JP 8048902 (1996)) relates to a kind of black and active dye composition, wherein proposes to use following golden yellow reactive dyestuffs as one of component of consisting of blended black look reactive dyestuffs.
Its general structure is:
Dyestuff Y
The Chinese patent (CN 1118796 (1996)) of Hoechst company application discloses similar foregoing.After this, the patent application CN 1443219 (2003) of Dystar company and WO 02/08341 (2002) disclose the series structure and the synthetic method thereof of above-mentioned dyestuff.
Wherein relate to dye structure of the present invention, for example have:
The inventor finds on the basis of a large amount of research trials, the composition that the general formula (1) of two kinds of reactive dyestuffs that expression is above-mentioned and general formula (2) dyestuff are formed all is significantly improved than the performance of wherein any single-activity dyestuff in degree of fixation, dye uptake and enhancing rate.Being worth pleasantly surprised is that the fast light discoloration that causes of Yellow active dye composition of the present invention also has clear improvement.

2. the single composition dyestuff of Yellow active dye composition of the present invention.
Table 1
Embodiment 1
Dyestuff A of the present invention and dyestuff B are used for pad dyeing dyeing, and the DYED FABRICS color and luster is bright-coloured golden yellow.Measure by relevant international standard, 4 grades of the washing fastness staining of DYED FABRICS, look become 4-5 level, 4 grades of dry fastnesses, fastness to wet rubbing 3-4 level, 4 grades of colour fastness to perspirations (alkali sweat), 4 grades of colour fastness to perspirations (sour sweat).
Dyestuff A of the present invention and dyestuff B are used for exhaust dyeing, and the DYED FABRICS color and luster is bright-coloured golden yellow.Measure by relevant international standard, 4 grades of the washing fastness staining of DYED FABRICS, look become 4-5 level, 4 grades of dry fastnesses, fastness to wet rubbing 3-4 level, 4 grades of colour fastness to perspirations (alkali sweat), 4 grades of colour fastness to perspirations (sour sweat).
Its working method is as follows:
Contaminate
To be the determined dyestuff of 1% weight with respect to fiber respectively, the solubility promoter of the dust-proofing agent of 0.2 weight % and 0.3 weight % be fully in the being dissolved in charging basket.Under the bath raio condition of 1:10, make fabric in overflow, keep circulation.Added the dye liquor of above-mentioned preparation in 10 minutes, temperature keeps 35 ℃, adds the sodium sulfate of 30 grams per liters after 10 minutes, is warmed up to 60 ℃ then, adds 30 grams per liter soda ash, is incubated 45 minutes, washes then, soaps, washes, dries.
Pad dyeing
Respectively by the consumption of 10 grams per liters with determined dyestuff, fully in the being dissolved in charging basket water, and add the dust-proofing agent of 0.2 weight % and the solubility promoter of 0.3 weight % separately.Put into the groove of continuous dyeing machine with dissolving sufficient dye liquor, fabric is dried after padding dye liquor, and the fabric after the oven dry is after cooling, pad 30 grams per liter soda ash, the padding liquid of 250 grams per liter sodium sulfate, decatize 1 minute in 100 ℃ saturation steam is washed then, is dried then.
The embodiment 2 fast light discolorations that cause

* DE explanation: with the dyeing fabric not illumination be standard specimen, it is big more that 8 hours look of illumination becomes DE, illustrates that it is photochromic serious more, the photochromic answer of the big more explanation of DE of placing 8 hours after the illumination is more little, variable color is big more.
As seen from the above table, reactive dye compositions of the present invention (dyestuff C) has the excellent fast light discoloration that causes.Compare with its composition homogencous dyes, it is fast light to cause discoloration and improves significantly and improve.
Below the explanation of each example, the measured value of the relative dye level of Yellow active dye composition of the present invention, dye uptake, degree of fixation is higher than all that its homogencous dyes is painted to be added and mean value, demonstrates fully its synergy.
Example 3 degree of fixation
Degree of fixation is for finally being accounted for the weight percent of dyestuff total amount by the adsorbed dyestuff of fabric.
The mensuration of degree of fixation is listed in table 6, table 7.
Table 6
Table 7
Degree of fixation by table 6, the visible Yellow active dye composition of the present invention of table 7 is higher than the degree of fixation that it forms homogencous dyes.
Example 4 dye uptakes
When dye uptake is different time points fabric on the amount of dying dye yield (testing apparatus: computer color measurement and color match instrument; Model: QuestXE; Producer: HunterLab) account for the weight percent of used dyestuff.Therefore, measure and calculate dye uptake respectively when dyeing, its result is shown in table 8, table 9 respectively.
Table 8
Table 9
As seen from the above table, adding and mean value when the dye composite dye uptake of actual measurement all is higher than single dyeing embodies its collaborative effectiveness.
Because dyeing is the industry of a high pollution, therefore, the characteristics of the relative dye level of Yellow active dye composition of the present invention, degree of fixation height, dye uptake can reduce sewage discharge, reduce the pollution to environment.
