use | dispersed red S-3GFL is yellow light and red, with excellent fastness, suitable for dyeing for various purposes, can be used alone, can also be combined with dispersed yellow brown H2RL and dispersed blue HBGL to form three primary colors to dye various medium and dark colors. It is mainly used for high temperature and high pressure dyeing of polyester and its fabrics, hot melt pad dyeing of polyester and cotton fabrics, and direct printing of polyester fabrics. It can also be used for direct printing of dyed diacetate, triacetate, acrylic and acetate fabrics. |
Production method | Using aniline and p-nitroaniline as raw materials, aniline and acrylonitrile are first subjected to cyanoethylation, and then with ethylene oxide Ethylation reaction, and then esterification with acetic anhydride to obtain the coupling component; then chlorination and diazotization of p-nitroaniline, and coupling with the above coupling component to obtain the product. The finished product is filtered, ground and dried.. |
