| Application | cationic Yellow 4G is mainly used for dyeing acrylic and its blended fabrics, it can also be used for dyeing of acetate fiber and polyvinyl chloride fiber. for dyeing and printing of acrylic fibers. Additives can be used for the dyeing of modified polyester and acetic acid fibers, and can also dye paper. It is suitable for direct printing on acrylic, modified polyester and acetic acid fiber fabrics. Dyed acrylic fiber is bright yellow, mainly used for dyeing acrylic fiber, fiber strip and wool. In addition to a separate dye brilliant yellow, often with cationic red GTL or red BL combined with bright orange to red. mainly used for dyeing acrylic fiber and its blend fabric |
| production method | by condensation of 1,3, 3-trimethylindoline acetaldehyde with 2, 5-bismethoxyaniline, salt, filtration and drying to obtain the finished product. Raw material consumption (kg/t)1, 3, 3-trimethylindoline acetaldehyde 4852, 5-bismethoxyaniline 370 with ω-aldehyde (1, 3, 3-trimethy1-Δ 2, Α-indolineac etaldehyde) and 2, 5-dimethoxyaniline as raw materials, condensation under acidic conditions, and then with ZnCl2 to form a double salt product. The final product was obtained by filtration and drying.. |
