Dyacid Red 3GP - Reference Information
| Use | weak acid red E-BL can be used for dyeing wool, silk and wool blends. It is mainly used for the dyeing of nylon fabric, and can also be mixed with other acid dyes to dye wool fabrics. Used for wool and other fibers in the same bath dyeing, nylon, silk color and wool similar, cellulose fiber does not stain. Can also be used for leather coloring. |
| production method | with 2-amino-n-ethylbenzenesulfonyl aniline and gamma acid as raw materials, the former is first diazotized, the product is then coupled to the latter. The final product was obtained by filtration, drying and pulverization.. |
