Properties and Usage
1. DESOAGEN S: When applied in pretreatment,before dyeing,it can transform the charge to increases the dye ability of anionic dye-stuffs.Thus, it evidently improves the depth of color. In order to avoid sedimentation of dyestuffs, the dyeing operation should be carried out in a fresh bath after pretreatment.
2. When anionic dyestuffs are used to dye the leather with low affinity, an intermediate treatment(sandwich method) should be carried out. There is an evident increase of color depth, brilliance and fullness.
3. When applied after the addition of formic acid and completion of dyeing, the fastness and fullness of color are enhanced.
