石榴皮染料对毛织物的染色性能研究

Dyeing Properties of Pomegranate Peel Dye to Wool Fabrics

本文研究了资源丰富的石榴皮染料溶液的耐热水稳定性,分析了染浴pH值、染色温度对石榴皮染料上染毛织物的影响,并测试了所染毛织物的色牢度及抗紫外性能。研究结果表明,石榴皮染料溶液耐热水稳定性好。石榴皮染料可采用直接染、铝、铁离子预媒染和后媒染多种染色方法对毛织物染色,不同染色方法可得到不同颜色的毛织物。直接染色法最佳染浴pH值为3,铁后媒染色法最佳染浴pH值为7,各种染色方法染色温度应为100℃。石榴皮染料染色毛织物具有良好的皂洗牢度、摩擦牢度和升华牢度,并具有很强的抗紫外性能。石榴皮染料可作为毛织物的一种功能型天然染料。

In this paper, the following aspects of the abundant Pomegranate peel dye were investigated： the stability of Pomegranate peel dye solution to heat water;the effects of the dye bath pH value, dyeing temperature on the color characteristic values of the dyed wool fabrics and the color fastness and the resistance to UV of the dyed wool fabrics. The resuhs showed that the Pomegranate peel dye solution had good stability to heat water. The direct dyeing method, pre-mordanting or after-mordanting dyeing method all can be used to dye wool fabrics with Pomegranate peel dye and the different dyeing methods can dye the different colors of the wool fabrics. For the direct dyeing method, the dye bath pH value of 3 was appropriate. For the iron after-mordanting dyeing method,the dye bath pH value of 7 was appropriate. The dyeing temperature of 100 ℃ was appropriate to the two dyeing methods. The dyed wool fabrics with Pomegranate peel dye had good color fastness properties to soaping, rubbing, sublimation and good resistance to UV. Pomegranate peel dye can be used as functional natural dye to wool fabrics.
