Amaryl Brilliant Yellow 4GX - Reference Information
| Use | reactive yellow K-4G can be used to dye cotton or viscose fiber with low affinity and fixation rate, therefore, it is mainly used for direct printing, and the shade color is applicable. It can also be used for printing and dyeing of silk fabric, silk and viscose silk fabric. For the printing of the vinylon fabric, the amount of color and the brightness are basically close to those on the cotton fabric. For the dyeing of polyester/cotton blended fabrics, can be used alone, can also be with the reactive brilliant orange K-GN, reactive brilliant red K-2G, reactive brilliant red K-2BP, reactive brilliant blue K-GR fight a variety of medium and deep color. for cotton, hemp, viscose, silk and other fabrics printing |
| production method | with aniline -2, 5-disulfonic acid, 2, 4-diaminobenzenesulfonic acid, cyanuric chloride, 1-(4 '-sulfophenyl)-3-methyl -5-pyrazolone as raw material, first of all, cyanuric chloride and aniline -2, 5-disulfonic acid condensation, and then with 2, condensation of 4-diaminobenzenesulfonic acid followed by diazotization of another amino group in the molecule of 2, 4-diaminobenzenesulfonic acid, followed by reaction with 1-(4'-sulfonylphenyl)-3-methyl -5-pyrazolone coupling, after salting out, filtration, drying to obtain the finished product.. |
