| 摘 要： | 以亚甲基蓝染料对阳离子染料可染涤纶(ECDP)短纤维进行染色,讨论了在ECDP短纤维染色过程中,染浴的pH值、染色温度、保温时间、染料浓度等因素对纤维染色饱和值(Sf)的影响。结果表明:染浴的pH值控制在4.5～5.0,纤维入染温度为50℃,以2℃/min的速率升到80℃,再以0.5℃/min的速率升到100℃,在100℃时保温时间为120 min;染料相对纤维的质量分数为5%～9%时,测得ECDP短纤维的Sf为8.4。

| Abstract: | An easy cationic dyeable polyester(ECDP) staple fiber was dyed with methylene blue dyestuff.The effects of pH value,dyeing temperature,heat preservation time and dyestuff concentration of dye bath on the dyeing saturation value(Sf) of the fiber were discussed.The results showed that the initial dyeing temperature was 50 ℃ and the dye bath temperature was heated from 50 ℃ to 80 ℃ at the rate of 2 ℃/min,continuously to 100℃ at the rate of 0.5 ℃/min and was kept at 100 ℃ for 120 min;ECDP staple fiber had Sf of 8.4 when the pH value of dye bath was 4.5-5.0 and the mass fraction of the dyestuff was 5%-9% based on the fiber. |
