These dyes can be solved by under solvent as liquid form:

Solving method:

Put solvent and dyes in the tank in the weight ratio of(20~25 dyes / 100 solvent). first, put solvent in the tank and dispel in high speed. during the dispersion, and dyes in the solvent slowly and dispel them for thirty minutes. after dispersion, USE filter to filter the solution. the dye solution should be used within one week.
