摘　　要：探讨了两性表面活性剂十二烷基二甲基甜菜碱(DDB)与N,O-羧甲基壳聚糖(NOCC)在活性翠蓝KN-G染色棉织物净洗中的作用。试验结果表明,DDB能够吸附到织物表面,提高织物表面的Zeta电位,导致净洗效果降低;而DDB与NOCC配合使用,则可以增溶织物上洗脱下来的浮色,改善净洗效果。Wash-off properties of zwitterionic surfactant dodecyl dimethyl betaine （DDB） and carboxymethyl chitosan （NOCC） on cotton fabric dyeing with reactive turquoise blue KN-G were discussed. The results showed that DDB can absorb onto the surface of the fabric to increase the Zeta potential of the fabric and lead to a decrease in the wash-off results. While the DDBcomplexes tend to improve the wash-off efficiency by synergistic solubilization the hydrolyzed dyes.
