摘　　要：为拓展桑椹色素的应用领域,以去离子水为提取剂对桑椹中的天然色素进行提取,研究桑椹色素对柞蚕丝织物及羊毛织物的染色性能,并对染色织物的紫外线防护效果进行测试。结果表明,利用桑椹色素对柞蚕丝织物及羊毛织物染色,适宜的pH均为3.0。当以硫酸亚铁、明矾及硫酸锌作为媒染剂进行预媒染色时,硫酸亚铁可引起羊毛织物及柞蚕丝织物试样色调变化,对提高试样染色深度效果最佳;直接染色试样的耐皂洗色牢度、耐日晒色牢度和耐湿摩擦色牢度仅为2级,各媒染织物的色牢度得到改善,可到达3级;羊毛织物及柞蚕丝织物经桑椹色素染色后紫外线透射率降低,2种织物的紫外线防护性能均得到显著提升。In order to expand the applications of mulberry pigment, in this study, the natural pigment was extracted from mulberry fruit by deionized water, and further applied for the dyeing and ultraviolet protective finishing of tussah silk and wool fabrics. The results showed that the optimal color strength for the dyeing of wool and tussah silk fabrics occurred at pH 3.0. In terms of the pre-mordant dyeing using ferrous sulfate, alum and zinc sulfate, ferrous sulfate caused the heavy change in color hue, but achieved the best enhancement on color depth. Directly-dyed fabrics only displayed level 2 during the measurement of color fastness to soaping, to light and to wet rubbing. However, the color fastness of all mordant dyeing fabrics was upgraded to level 3. The ultraviolet transmittance of wool and tussah silk fabrics dyed with mulberry pigment decreased significantly, indicating the great improvement of the ultraviolet protection performance of both fabrics.
