Other Name: Disperse Red 2E-FB,Disperse Red 3B,Disperse Red 3BR,Disperse Red E-3B,Disperse Red E-4B,Disperse Red FB,Disperse Red FBR,Plastic Red 307,Terasil Red FB
Molecular Formula:C₂₀H₁₃NO₄
Molecular Weight: 331.32
Manufacturing Methods : In alkaline medium 1-Amino-2-bromo-4-hydroxyanthracene-9,10-dione and phenol condensation
Properties and Applications: Bright red blue light. Purple powder evenly. Soluble in 50% of acetone for red, soluble in four hydrogenated naphthalene and xylene. The strong sulfuric acid solution for yellow, the alkali sensitive. Dyeing met in the copper, iron ion color becomes shallow. This product used for polyester and their blended fabric dyeing and printing, for the bright red light blue light, the sun good fastness, weeks of high temperature and high pressure, the dyeing temperature is 125 ~ 130 ℃, good levelness. Dye polyester/ Wool blended fabric of wool with less color . The sublimation fastness is poorer, melt method only appropriate spell dye light color. When two vinegar fiber dyed with polyester similar color shade, the dyeing speed slow. Good levelness, but dye deep the gender is poorer. Three vinegar is dyed fiber dyed deep sex is better. Dyeing nylon is blue color, the dyeing speed is slow, levelness and dye deep sex medium. So when a black silk ribbon with colored light blue, the dyeing rate is low, soaping fastness is bad two this product can be used for nylon polyester fabric or the direct printing, be not white color, suitable for transfer printing. To calcium, iron ion is very sensitive, dye bath these ions are colored light slant blue:
