| 摘 要： | 将双氰胺作为双氧水活化剂应用于棉针织物低温练漂工艺,结果表明,双氰胺对双氧水具有一定的活化作用,能促进双氧水的分解.H2O2/双氰胺活化体系低温练漂织物的白度和毛效与传统工艺相当,强力损失小,染色得色率高.该体系成本低,排放废水的色度、BOD、COD值均较低,有利于节能减排.

| Abstract: | Low temperature scouring and bleaching of cotton knits is carried out with dicyandiamide as the peroxide activator.The results show that dicyandiamide can accelerate the decomposition of peroxide.Compared with the traditional process,H2O2/dicyandiamide activation scouring and bleaching process features similar whiteness and capillary effect,lower strength loss,higher color yield,reduced cost and chroma,BODandCODvalue of effluents,and it is of benefit to energy conservation and emission reduction. |
