After oxygen bleach of cotton fabric the remains of oxyful affect a lot on the dyeing of active dyes.

棉织物氧漂后残余双氧水对活性染料染色影响较大。

Compared with the prior art, the amount of the oxyful in use is greatly reduced, and the production cost remarkably decreases.

与已有技术相比，双氧水用量大为下降，生产成本明显下降。

According to the invention, the method is simple, the slag mount is small, the oxyful has wide source, and the waste of natural resource is reduced.

本发明的方法简单，渣量少，双氧水来源广，减少了对自然资源的浪费。

In the method, the reaction of the oleum and the oxyful relatively improves the concentration and the oxidization capability of the oxyful and reduces the decomposition speed of the oxyful;

本方法中发烟硫酸与双氧水反应相对提高了双氧水的 浓度，提高了双氧水的氧化能力，降低了双氧水的分解速度；
