C.I.Reactiveyellow2 - Reference Information

color index 18972
LogP-4.47
EPA chemical information Information provided by: ofmpub.epa.gov (external link)
use reactive light yellow K-6G can be used for dyeing cotton or viscose fibers, but it has low affinity for fibers and poor chlorine bleaching fastness. It is mainly used for direct printing of cotton or viscose fiber fabrics. Due to its low affinity for fibers, it is not fixed and has good washability and does not stain the white ground. Single-use dyeing of tender yellow is incomparable, and it is K-GL with reactive turquoise blue to dye fresh and tender green, and K-G with reactive orange to dye golden yellow. It can also be printed with soluble vat dyes, but it is not suitable for printing on color phenol yellow cloth. It can also be used for dyeing wool, silk, nylon, vinylon, and direct printing of silk. Compared with reactive light yellow X-6G, polyester-cotton blended fabric dyed in the same bath with disperse dyes has better soaping fastness and less white soil pollution.
used for dyeing cotton and viscose fiber
used for printing cotton, hemp, viscose, silk and other fabrics
Production method Using 2,4-diaminobenzenesulfonic acid, p-aminobenzenesulfonic acid, cyanuric acid and 1-(2 ',5'-dichloro-4 '-sulfophenyl)-3-methyl -5-pyrazolone as raw materials, first 2, 4-diaminobenzenesulfonic acid is condensed with melamine, and then the condensation product is diazotized, it is coupled with 1-(2',5 '-dichloro-4'-sulfophenyl)-3-methyl -5-pyrazolone, and finally condensed with p-aminobenzenesulfonic acid, salted out, filtered, and dried to obtain the finished product..
