| use | cationic yellow 7GLL is mainly used for dyeing acrylic fiber, with stable color light (greener) and good color fastness. It is also used for dyeing diacetate fiber and silk, and can be used for direct printing of acrylic diformaldehyde fiber and silk fabric. It is also used for dyeing brocade nitrile blends, nylon rarely touches color. It forms three primary colors with cationic red GTL and cationic blue 5GL, which can be dyed in medium to dark colors. |
| Production method | Using ω-aldehyde and 2-methylindole as raw materials, the two are condensed in the presence of phosphorus oxychloride to obtain the product.. |
