摘要
将溶胶一凝胶法用于活性染料的固色处理,对4只活性染料研究了染色后皂煮和不皂煮两种情况下的固色效果。对于染色后皂煮的活性染料染色布样,经溶胶一凝胶处理后,皂洗牢度和湿熨烫牢度的原样变色略有下降,白布沾色提高,△E值均有所降低;对于染色后不皂煮的活性染料染色布样,皂洗牢度和湿烫牢度的原样变色和白布沾色均提高0.5-2.0级。对其固色机理进行了初步探讨。
The sol-gel process was used to fix four reactive dyes, then the effectiveness of the fixation, both with and without soaping after the fabrics were dyed, was studied. For both wash fastness and wet iron fastness, there was slight color change, but color staining on the adjacent white cloth was enhanced and AE values were lower, as compared with untreated samples. The unsoaped samples showed moderate color changes and both wash fastness and wet iron fastness color staining improved by 0.5-2.0 levels. The fixation mechanism was also investigated and discussed.
