【摘要】 通过单因素试验及正交试验,探讨了3只活性染料对改性真丝染色的最佳工艺:Cibacron红FN染色温度70℃,硫酸钠浓度20 g/L,碳酸钠浓度3 g/L;Cibacron红LS染色温度60℃,硫酸钠浓度10 g/L,碳酸钠浓度2 g/L;DyStar红XL染色温度50℃,硫酸钠浓度20 g/L,碳酸钠浓度1 g/L。改性真丝织物用双活性基活性染料染色时,其上染率及固色率均比未改性织物有很大提高,盐用量则可减少至原来的1/3。更多还原

【Abstract】 Via single factor and orthogonal tests,optimum processes of modified silk fabric with 3 reactive dyes were defined as follows,dyeing temperature of 70℃,60℃ and 50℃,sodium sulfite of 20g/L,10g/L,20g/L and soda ash of 3 g/L,2 g/L,1 g/L for Cibacron Red FN,Cibacron Red LS,Dystar Red XL respectively.The rates of exhaustion and fixation of bifunctional reactive dyes on modified silk fabric were improved remarkably,the amount of salt can decrease to 1/3 of conventional dosage,burden on wastewater treatment was greatly lessened.更多还原
