Background
VB blue-RS is mainly processed by mixing 72 percent of reduced RSN blue, 15 percent of reduced blue BO and 2513 percent of reduced black, and is fed according to different proportions for coarse grinding → suction material → calibration → fine grinding → filtration → spray drying → finished product packaging. The vat RSN blue is also called vat 4 blue, vat black 25 is also called vat olive T, vat blue BO is also called vat 20 blue, vat red 15 is also called vat purplish red, vat olive green B is also called vat olive green 3.
The reduced RSN blue has a relatively bright saturation degree and is slightly different from that of the reduced VB blue-RS, so that a little reduced blue BO and reduced black 25 are added, the reduced RSN blue is generally used for high-quality cotton cloth, and the cost price is relatively high, so that the problem that how to prepare the high-saturation reduced blue and the manufacturing cost can be reduced is urgently needed to be solved at present.
