I want to know if the samples of the cloth to be produced are made in the process department, then what is the process like in the dyeing and finishing factory? Please talk to someone who knows the inside story. It's a little troublesome. I did a small experiment on decolorization of printing and dyeing wastewater. Generally, 19 dye is used for dyeing. Each group is dyed with white blank and then dried (there are two sets of instruments). Each group lasts about four hours, which can amplify the dyeing effect of different dyeing doses. According to the same principle, fabric samples can be made. I don't know if I ask this, Khan?
