| Use | disperse red S-FL is used for dyeing polyester and its blended fabrics, which is suitable for dyeing deep color by high temperature and high pressure method. Can be used for direct printing of polyester fabric, also used for dyeing two acetic acid fiber, three acetic acid fiber, used to dye nylon color light is blue, up dyeing is poor, for dyeing acrylic fiber can be light color. for dyeing and printing of polyester and its blends |
| production method | with 2-cyano-4-nitroaniline and N-cyanoethyl-N-acetoxyethylaniline as raw materials, the product is first obtained by diazotization of 2-cyano-4-nitroaniline and coupling with N-cyanoethyl-N-acetoxyethylaniline. The final product was obtained by filtration, grinding and drying.. |
