桉树皮提取液对真丝织物染色性能的研究

采用水溶液提取桉树皮色素,利用气相质谱-色谱联用仪(GC-MS)分析水抽提物中的有效成分,并将其用于真丝织物的染色;探究了染色方法、媒染剂种类、媒染剂质量分数、染色温度及染色时间对真丝织物染色性能的影响。结果表明:使用明矾、硫酸铝、硫酸锌、硫酸铜作为媒染剂时,最佳的染色方法是同浴媒染法,优化染色工艺为浴比1︰50,硫酸铜质量分数5%,染色温度95℃,染色时间50 min。媒染剂对真丝织物的颜色特征值有影响,且媒染能提高其各项色牢度等级,尤其是耐光色牢度。

Study on dyeing performance of eucalyptus bark extract to silk fabrics

Pigments of eucalyptus bark were extracted in water,and its effective components were analyzed via GC-MS(Gas Chromatography Mass Spectrum).The pigments were then applied to dye the silk fabrics,and the effects of dyeing method,mordant type,mordant mass fraction,temperature,and time on the dyeing property were explored.Results indicate that the optimal dyeing method is the one-bath mordant dyeing method when the alum,aluminum sulfate,zinc sulfate and cupric sulfate were taken as the mordant,and the optimized conditions are as below:bath ratio 1︰50,mass fraction of copper sulfate 5%,temperature 95℃,and time 50 min.Additionally,the mordant has an influence on the characteristic value of silk fabrics color,and could improve the color fastness,especially the light fastness.
