| use | direct sun-resistant red F3B can be used for dyeing cotton and viscose fibers to obtain bright red. Levelness and transfer dyeing are poor, poor hiding power to viscose fabric with uneven quality and good dyeing rate. It can be used for dyeing rich fiber, silk and wool, and also for high-temperature dyeing polyester viscose blended fabric in the same bath with disperse dyes. It is also used for direct printing of cotton, viscose fiber and silk fabric. used to verify the staining of collagen diaphragm (collagenous septa) |
| Production method | Using p-aminobenzene sulfonic acid, o-aminobenzene sulfonic acid, J acid and phosgene as raw materials, the p-aminobenzene sulfonic acid is first diazotized, then coupled with o-aminobenzene sulfonic acid, and then subjected to the second diazotization, coupled with J acid, and condensed with phosgene to obtain the product. The finished product is salted out, filtered, dried and crushed.. |
