Abstract：Cottonfabricwasdyedbyleucoimmersiondyeingwitholivegrenandsandbrown，thereducedbio-baseddyes，and theliftingpropertiesofthedyes werediscussed.Theeffectsoffourfactors，namelythemassconcentrationofreducingagentZ， themassconcentrationofsodiumhydroxide，dyeingtemperatureanddyeing time，onthereductionpotentialandK/Svaluewere analyzed.Thedyeingprocesswasoptimizedbyorthogonaltest.Therubbingfastnessandsoapingfastnessofdyedfabricwere tested.The results showed thatthe optimized processconditions ofthe two dyes were as follows：dyeing with 5% dye concentration （omf），reducing agent Z11g/L ，sodium hydroxide 10g/L ，dyeing temperature 75∘C ，and dyeing time 40min .The soaping and rubbing fastness of the fabric are up to 4 and above，and the fastness is excellent.

生物基染料通常采用农业或草药行业的天然废料，经过微生物精密发酵技术后制成，生物基染料的结构有多种，多以类胡萝卜素、α-萘醌、葱醌、花色素、靛蓝类色素为主，从应用类型看，多类似于酸性类染料、直接染料、分散染料和还原染料等[1-3]。（剩余3965字）
