Use | disperse Violet H-FRL is suitable for dyeing polyester and its blended fabrics, dyeing polyester with high temperature and high pressure, and dyeing light to medium color. It can be used with the same bath of vat dye for Hot Melt rolling dyeing of polyester cotton cloth, and with reactive purple K-3R pulp for direct printing of polyester cotton cloth. The whiteness of bleached polyester cotton fabric can be improved by using disperse Violet H-FRL and fluorescent whitening agent DT in the same bath. It can also be used to dye triacetate fiber, but it is not suitable for dyeing diacetate fiber, nylon and acrylic fiber. can be used for a variety of plastics, polyester coloring |
production method | the product is obtained from 1, 4-diaminoanthraquinone as a raw material by condensation with phenol after chlorination. The final product was obtained by filtration, grinding and drying.. Add 3.07 parts of 1, 4-diamino-2, 3-dichloroanthraquinone, 5.65 parts of phenol, 5.2 parts of aqueous potassium hydroxide solution, 23.1 parts of benzyltriethylammonium chloride and 7.7 parts of water to the reaction kettle, the product was obtained by heating at 100 °c for 20H. |
