姜黄染料对柞蚕丝织物的染色性能研究

Dyeing Behavior of Turmeric Dye on Tussah Silk Fabric

从姜黄中提取天然染料,研究姜黄染料对柞蚕丝绸的染色性能及功能性。探讨染色工艺参数如染色温度、染色时间、染浴p H值对染色织物K/S值的影响,研究了媒染剂硫酸锌、硫酸铝、硫酸亚铁对试样K/S值及色泽的影响,测试了染色柞蚕丝织物的染色牢度及其抗紫外线、抗菌性能。结果表明,天然姜黄染料对柞蚕丝织物的上染性能良好,媒染剂显著影响试样的色泽及染色深度。姜黄染色柞蚕丝织物具有优良的紫外线防护性能及抗菌性能。

Natural dyes were extracted from turmeric,and the dyeing properties and functions of the dyes on tussah silk were studied.The influence of dyeing process parameters such as dyeing temperature,dyeing time and dye bath pH value on the K/S value of dyed silk were discussed.The influence of mordants(zinc sulfate,aluminum sulfate and ferrous sulfate)on K/S value and color luster of dyed samples were also studied.Furthermore,the color fastness,anti-ultraviolet property and antibacterial activity of the dyed tussah silk were tested.The results show that the natural curcumin dye is good for silk dyeing,and the color luster and color strength of the sample are significantly influenced by mordants.Tussah silk fabrics dyed with turmeric extracts have excellent UV protection properties and antibacterial activity.
