| Use | direct sun-resistant green BLE is mainly used for cotton, viscose fiber dyeing and direct printing of fabric, blue green. Poor migration. It can also be used for dyeing and printing of silk and its fabrics. High-temperature dyeing polyester-viscose blended fabric with disperse dyes in the same bath, the color light is basically unchanged. When used for viscose fiber and other fibers in the same bath dyeing, the wool is dark and light, the silk is lighter, the nylon is stained, the two acetate fiber, triacetate fiber, polyester, acrylic is non-staining. Cotton and viscose fiber can be treated with fixing agent M and fixing agent Y to improve the wet treatment fastness. The color light after the treatment of the fixing agent M is yellow, and the color light after the treatment of the fixing agent Y is green. Can also be used for paper, leather, regenerated cellulose film dyeing. |
| production method | with H acid, klixidine, P-nitroaniline, salicylic acid, aniline, cyanuric chloride as raw materials, the first nitroaniline diazotization, after coupling with salicylic acid and reduction of its nitro group, it is condensed with cyanuric chloride and aniline, H acid. Another molecule of the H acid is then diazotized, coupled to the clidine, and the amino diazotization in the coupled product is continued to be coupled to the aforementioned condensation product to give the product. After salting out, filtration, drying, grinding to get the finished product... |
