Some advice during using soap yellow dyes 

1.Color pulp and water treatment. Firstly, the soap yellow dyes should be slurried with warm water, then heated and stirred continuously until the dyes are basically dissolved. Soap yellow dye is not resistant to hard water, and most of it can combine with calcium salt or magnesium salt to form insoluble precipitation. Therefore, soft water dyeing must be used.

2.The control of dyeing temperature, dyeing temperature can depend on the type of dye performance, generally between 80℃- 90℃. Good levelness, color fastness and light fastness can be obtained if the temperature is properly controlled.

3.The dyeing time should be based on the different dyeing rates of dyes. 

4.Add dyeing auxiliaries.

Except yellow color, our Rhodamine B can be used for pink color soap dyeing, welcome your inquiry if necessary.
