use | weakly acidic yellow RXL is used for dyeing wool, silk, nylon and their blended fabrics. It can also be printed directly on wool and silk fabrics. High dyeing rate, good leveling. When used for dyeing wool with other fibers in the same bath, the diacetate fiber is slightly stained, and the triacetate fiber is not stained. |
Production method | Using 4-p-aminoaniline-3-nitrobenzene sulfonic acid, m-cresol, and p-toluenesulfonyl chloride as raw materials, first 4-p-aminoaniline-3-nitrobenzene sulfonic acid is diazoated, then coupled with m-cresol, and finally the coupling product is condensed with p-toluenesulfonyl chloride to obtain the product. The finished product is filtered, dried and crushed.. |
