2-Chloro-4-nitrobenzenamine diazo, and 3-Propanoylamino-N,N-bis(2-acetoxyethyl)benzenamine?coupling.Properties and Applications
Blu-ray is red. Deep red powder. Dye bath of copper, iron ion in light of the impact is not big. Dyeing appropriate pH value for 4 ~ 5. The dye is suitable for high temperature and high pressure dyeing method, dye when light color levelness poor; Carrier dyeing method performance is poor; Use hot melt temperature dyeing method to more than 200 ℃. Dye three vinegar fiber, colored light than a little yellow polyester, dye two vinegar fiber with colored light when polyester similar, but the dyeing rate is low, not suitable for dyeing acrylic, can be in polyester direct printing, can also be polyester/cotton the discharge of, shallow background, can’t and the active dyes containing alkali agent with plasma printing.| Standard | Ironing Fastness | Light Fastness | Persperation Fastness | Washing Fastness | |||
