| use | direct ash d is widely used for dyeing cotton and viscose fabric, and also for dyeing and printing silk fabric, resulting in green and red gray to green and black, with deep and thick color and uniform color. It can also be matched with yellow, red, blue, brown and other dyes. After dyeing, the fixing agent Y or fixing agent M is commonly used for treatment and urea-formaldehyde resin finishing. It can also be used for dyeing vinylon fabrics. It is mainly used for dyeing cellulose fiber fabrics such as cotton, hemp, viscose, etc., and can also be used for dyeing silk, nylon and their blended fabrics, and can also be used for printing viscose and silk fabrics. After dyeing cotton and viscose fabrics, this product is usually treated with fixing agent Y or fixing agent M, and treated with urea-formaldehyde resin. After fixing agent Y treatment, the color light is reddish; after fixing agent M treatment, the color light turns dark, and after urea-formaldehyde resin finishing, the color light is basically unchanged. Mainly used for dyeing cotton, hemp, viscose and other fabrics |
| production method | p-nitroaniline is diazotized, coupled with kressi (primary coupling), and the primary coupling is diazotized (secondary diazotization), and then coupled with γ acid (secondary coupling), and then reduced the nitro group to amino group with sodium sulfide, and then salted out, filtered and dried. Kg/ton p-nitroaniline (100%) 95 klioxitin (100%) 96 γ acid (100%) 110 sodium nitrite (industrial) 105 using p-nitroaniline, 3-methyl-6-methoxyaniline (klioxitin) and γ acid as raw materials, first diazotization of p-nitroaniline is coupled with klioxitin, then diazotization of the coupling product, coupling with γ acid, and finally reducing the nitro group with sodium sulfide to obtain the product. The finished product is salted out, filtered, dried and crushed.. |
