| use | reactive light yellow X-7G is mainly used for twisting cotton and viscose fibers and dyeing of fabrics, as well as direct printing of their fabrics, with a sun fastness of grade 6. It is also used for printing copper ammonia fiber fabrics. When used for dyeing cotton or viscose fiber and other fiber blended fabrics in the same bath, polyester, polypropylene and acetate fiber are not stained, vinylon and wool are stained, and nylon is stained seriously. When used alone, the color is green, which is one of the delicate varieties in yellow. It can be X-BR with reactive brilliant red X-B and reactive brilliant blue to form three primary colors and dye various light colors. It can also replace reduced yellow GCN and reactive blue dye to dye brilliant green or fruit green. |
| Production method | Using 1,3-diaminobenzene-4, 6-disulfonic acid, cyanuric chloride, N-methyl-3-carbamoyl-4-methyl-6-hydroxy-2-pyridone as raw materials, first 1, 3-diaminobenzene-4, 6-disulfonic acid is condensed with cyanuric chloride, then diazotization, and finally coupled with N-methyl-3-carbamoyl-4-methyl-6-hydroxy-2-pyridone, salted out, filtered, and dried to obtain the finished product.. |
