摘　　要：采用配位络合物(酒石酸或柠檬酸/FeSO4/三乙醇胺)替代传统的保险粉进行还原艳绿FFB染色,以减少保险粉染色后产生的含硫化合物的毒性。试验从还原电位方面证明酒石酸或柠檬酸配位体系来代替保险粉的可行性,并发现还原染料采用配位体系染色,织物的K/S值比保险粉体系高,摩擦牢度则与保险粉染色体系相近。Novinone Green FFB vat dyeing was carried out with coordination system with tartaric acid or citric acid and ferrous sulfide and triethanolamine instead of traditional sodium dithionite, therefore, toxicity caused by sodium dithionite in dyeing effluents was greatly reduced. Trials showed that dyeings with the coordination system featured higher K/S value and similar rubbing fastness compared with those with sodium dithionite. Reduction potential further proved that citric acid or tartaric acid coordination system was feasible to act as a substitute for sodium dithionite in vat dyeing.
