By table 1 as seen, at dyeing concentration 1～6% o'clock, power part measured value of Yellow active dye composition 1～6 of the present invention all is higher than single adding and mean value when planting pure dye dyeing, has embodied significant collaborative effectiveness.
2. degree of fixation
Degree of fixation is promptly finally accounted for the weight percent of the total consumption of dyestuff by the adsorbed amount of dye of fabric.Therefore, after dyeing is finished, survey not by the adsorbed dye strength of fabric (testing apparatus: computer color measurement and color match instrument; Model: QuestXE; Producer: HunterLab), promptly be free on the amount of dye in the aqueous solution, with its divided by total consumption of dyestuff to obtain degree of fixation, its result is shown in table 2 respectively.
Table 2 degree of fixation

| Dyestuff II 2 | 0 | 100 | 72.00 | - |
By table 1 as seen, adding and mean value when the dye composite degree of fixation of actual measurement all is higher than single dyeing embodies its collaborative effectiveness.
Because dyeing is the industry of a high pollution, therefore, power part of Yellow active dye composition of the present invention, the characteristics that degree of fixation is high can reduce sewage discharge, reduce the pollution to environment.
3. perviousness
The tester number of plies that each dyestuff institute porous of visual observations arrives, it the results are shown in table 3 (the tester number of plies that dyestuff institute porous arrives is many more, and the perviousness of dyestuff is good more).
Table 3 perviousness
| Dyestuff | Form | Perviousness (layer) | |
| Dyestuff I | Dyestuff II | ||
| Yellow active dye composition 1 | 80 | 20 | 4 |

| Yellow active dye composition 3 | 20 | 80 | 4 |
| Dyestuff I 1 | 100 | 0 | 4 |
| Dyestuff II 1 | 0 | 100 | 3 |
As seen from Table 3, the perviousness of Yellow active dye composition all reaches 4 layers, and only 3 layers of the perviousness of homogencous dyes II.The perviousness of this explanation Yellow active dye composition does not descend because having sneaked into the relatively poor dyestuff II of perviousness.
4. dye uptake
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: Quest XE; Producer: HunterLab) account for the weight percent of used dyestuff.Therefore, when dyeing, measure and calculate dye uptake respectively at each time point shown in the table 4, its result is shown in table 4 respectively.
Table 4 dye uptake

| 90 minutes add and mean value | 76.6 | 82.2 | 87.8 | - | - | ||||
From last table as seen, dyestuff I is the dye uptake height just, and final dye uptake is lower again.And the first dye uptake of dyestuff II is low, and final dye uptake is high again.Therefore, in dyestuff I and II and other redness, when blue active dye is pieced together the union dyeing look, though present certain superiority, compatibleness is relatively poor.
Compare with homogencous dyes, the first dye uptake of Yellow active dye composition decreases, and final dye uptake is greatly improved again, thereby reaches slow purpose of dying level dyeing and high dye uptake.And final dye uptake is higher than adding of homogencous dyes and mean value, has synergistic effect, comparatively mates with the dye uptake curve of other redness, blue active dye, thereby improved compatibleness with other dyestuff (red, blue dyes).
This shows that the present invention has obtained a kind ofly can improve the prior art deficiency, power part, degree of fixation, with other compatibility of dyes and level-dyeing property on have the Yellow active dye composition of marked improvement.
