Summary
Disperse Red 3B is the main dyestuff for polyester. It has bright color, good light fastness, good levelness and poor sublimation fastness. It is often combined with disperse yellow RGFL and disperse blue 2BLN to form three primary colors. It is suitable for high temperature and high pressure dyeing. It can be used for direct printing and transfer printing of polyester and nylon fabrics. The properties of diacetate fiber and triacetate fiber are similar to those of polyester fiber. The dyeing of nylon and acrylic fiber is bluer, the dyeing speed is slower, and the levelness and dyeing depth are medium.
