中文摘要：
为了缩短棉针织物前处理和染色时间，针对过氧化氢酶酶解和染色同浴处理造成的染色不稳定问题，研究在过氧化氢酶处理棉针织物漂白残液后的酶解液中进行活性染料同浴染色的可行性，与常规分浴工艺作比较；考察H2O2的不同残余浓度对单一和拼混活性染料色光的影响。结果表明：残余H2O2对活性嫩黄4-GL、活性红B-3BF、活性深蓝B-2GLN的染色效果影响较大，而对其余活性染料影响较小；在酶解、染色同浴工艺中发现，通过采用软水、减少重金属离子含量、适当添加电解质和染料用量等方法，有助于提高酶解、染色同浴工艺的染色效果。
英文摘要：
In order to shorten pretreatment and dyeing process and improve the stability of enzymatic hydrolysis and dyeing in one bath, reactive dyeing of knitted cotton with the catalase-treated bleach effluents in one bath was investigated by comparing with traditional process. The effects of various concentration of H2O2 on the shade of the fabrics dyed with pure reactive dyes and mixed dyes were also observed. The results indicated that H2O2 had negative effect on the dyeing in the presence of Reactive Yellow 4-GL, Reactive Red B-3BF and Reactive Dark Blue B-2GLN. However, the effect on other dyes was insignificant. The enzymatic hydrolysis and dyeing effect in one bath can be improved by using soft water, decreasing the content of metal ions, adjusting electrolyte and dyes quantity.
