雄蚕丝酸性染料染色性能研究

Dyeing property of Male Silk Dyeing with Acid Dyes

采用酸性染料染雄蚕丝,探讨了pH值、元明粉用量、染色温度等因素对染色效果的影响。结果表明,天龙染料染雄蚕丝的上染率、提升力均较高,且各项染色牢度也较好。得到理想的染色工艺为:元明粉15 g/L,pH6,室温入染,升温至90℃,保温60 min。

Male silk dyeing with acid dyes were carried out, factors of pH value, sodium sulfate addition, as well as temperature were discussed on dyeing results. Results showed that the dyeing featured higher dye uptake, as well as satisfactory color fastness. The optimum conditions were： sodium sulfate 15 g/L, pH value 6, raising the temperature from room temperature to 90℃, then keeping at this temperature for 60 minutes.
