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農(nóng)業(yè)或草藥行業(yè)的天然廢料,經(jīng)過微生物精密發(fā)酵技術(shù)后制成,生物基染料的結(jié)構(gòu)有多種,多以類胡蘿卜素、α-萘醌、蔥醌、花色素、靛藍(lán)類色素為主,從應(yīng)用類型看,多類似于酸性類染料、直接染料、分散染料和還原染料等[1-3]。(剩余3965字)
