Acid Red 57 Use and Manufacturing

Methods of Manufacturing

Using 2-amino-N-ethylbenzenesulfonanilide and gamma acid as raw materials, first diazotize the former and then couple with the latter to obtain the product. After filtering, drying and crushing, the finished product is obtained.

Uses

Weak acid red E-BL can be used for dyeing wool, silk and wool blends. It is mainly used for dyeing nylon fabrics, and it can also be used to dye wool fabrics with other acid dyes. When used for dyeing wool and other fibers in the same bath, nylon and silk are similar in color to wool, and cellulose fibers do not stain. Can also be used for leather coloring.
