The introduction of leucotrope W and O of printing paste

1.Leucotrope W:it is also called etherification agent W.Leucotrope W can be used as VAT dye,organization.When discharge printing land color can help to discharge white.If use reductant rongalite to discharge,can make the land color VAT dye reduction into leuco in air,it is very easy to be oxidized into prototype,when leucotrope W exist,it will disintegrate itself into a chloride phosphomycin calcium and benzene dimethylamine,chlorinated chiral sulfonic acid calcium salt and leuco ether combine into water soluble ether compound,after washed that produces good discharge effect.

2.Leucotrope O:it is also called etherification agent O.Leucotrope O can be used as VAT dye or discharge agent for sulfur dye discharge printing,the principle is similar with Leucotrope W.
