Soaping agent DHK138P is compound of multi-carboxylic, multi-hydroxyl and specially active inorganic salt. It has very good affinity with hydrolyzed reactive dyes, so it has excellent ability of anti staining and washing off and can effectively remove unfixed dyes and prevent re-dyeing when used as soaping agent after dyeing and printing. It can work at 60-90℃, but it has better performance at temperature of 80-90℃. It can make color of soaping residual more light.
Characteristics and advantage
◎ Very excellent anti-staining ability and effectively remove unfixed dyes.
◎ There is no residual of soaping agent on fabric because it is easy to be washed off.
◎ Color of soaping residual obviously becomes light when dosage is increased.
◎ Very low foaming.
◎ It saves water, time and energy because drainage color after soaping is very light.
