摘要
将活化氧化体系应用于棉织物K型活性染料染色后的清洗工艺,研究了添加剂及清洗条件对净洗残液脱色率和织物清洗效果的影响.结果表明:四乙酰乙二胺(TAED)/H2O2活化氧化体系可使活性艳红K-2G染料溶液的脱色率达到58.92%,过硫酸铵、氯化镁对TAED/H2O2活化氧化脱色体系具有协同作用,可使活性艳红K-2G染料溶液的脱色率提高到91.43%.经复合活化氧化清洗后织物K/S值相比常规皂洗下降不大,色光变化较小,色牢度还略有提高,而且净洗残液的脱色率达到较高水平,CODCr降低约40%,减轻后期废水处理负荷,降低生产成本.
Activation oxidation system was applied in cleaning procedure of cotton fabric dyed with K type reactive dye.The effects of additives and rinsing condition on decolorization rate of rinsing liquor and cleaning re-sult of dyed fabric were investigated.The results indicated that the color removal rate could reach 58.92% through the application of tetraacetylethylenediamine（TAED）/H2O2 activation oxidation system in Reactive Red K-2G.Combination of MgCl2,（NH4）2S2O8 and TAED/H2O2 had a synergistic effect on the decolorization,which could increase the decolorization rate of Reactive Red K-2G to 91.43%.When the composite oxidation system was applied to the soaping process of cotton fabric,the K/S values and the color differences of the rinsed fabric changed little compared with that of normal rinsed fabric.And the color fastness slightly increased,the color re-moval rate of rinsing liquor could reach a high level.Besides,oxidation cleaning could decrease the CODCr of rins-ing effluent by 40%,which was helpful for alleviating the load of wastewater treatment and lowering the total cost of production.
