摘要
从柞叶中提取天然染料,研究该染料对Fe2+、Cu2+、Al3+以及对pH值变化的稳定性。以柞树叶染料对棉织物进行轧染试验,探讨了媒染剂种类、用量、焙烘温度和焙烘时间对染色性能的影响。结果表明,柞叶染料对弱酸条件及金属离子具有相对稳定性,对碱性条件较为敏感。柞叶染料对纯棉织物轧染的优化工艺条件为:以硫酸亚铁为媒染剂,后媒法染色,硫酸亚铁15 g/L,135℃焙烘2.5 min。采用此工艺染得的棉织物得色深,皂洗及摩擦牢度均较好。
A natural dye is extracted from oak leaves, its stabilities to Fe2＋ ,Cu2＋ ,Al3＋ ions and pH value are studied, and then is applied to pad dyeing of cotton fabric. The influences of the kind and dosage of mordant agent, curing temperature and time on dyeing results are discussed. The results show that the oak leaves dye is stable to weak acid and metal ions, and is sensi- tive to alkaline （pH 〉8） conditions. The optimum pad dyeing process with oak leaves dyes is as follows： post mordant dyeing with ferrous sulfate 15 g/L, curing at 135 ℃ for 2.5 min. The cotton dyeings feature good color yield and color fastness to soa- ping and rubbing.
