摘　　要：为提高柞蚕丝织物的抗紫外线性能,同时获得较为齐全的色谱,采用天然姜黄染料及黑米染料对柞蚕丝进行同浴拼色染色,研究两种染料配比及FeSO_(4)后媒染处理对柞蚕丝颜色及抗紫外线性能的影响。结果表明,将姜黄染料和黑米染料进行拼色可以得到从黄色到暗红色等一系列色泽的染色柞蚕丝,FeSO_(4)媒染可进一步丰富柞蚕丝的色谱,得到暗黄、黄绿、暗蓝等一系列色泽;FeSO_(4)媒染试样染色牢度达到3级以上。与单一染料染色试样相比,同浴拼色染色试样的紫外线防护性能更佳,且FeSO_(4)媒染可以进一步提高试样的UPF指数,最高可达到45.88。In order to improve the anti-ultraviolet performance of tussah silk fabric and obtain a complete color spectrum,natural dyes extracted from turmeric and black rice are used to dye tussah silk in one-bath process.The effects of the ratio of two dyes and ferrous sulfate post-mordant treatment on the color and anti-ultraviolet performance of tussah silk are studied.The results show that by combining turmeric dye and black rice dye,a series of colors from yellow to dark red can be obtained.Ferrous sulfate mordant dyeing can enrich the color of tussah silk,and a series of colors such as dark yellow,yellow-green and dark blue can be obtained.The color fastnesses of mordant dyeings are above Grade 3.Compared with samples dyed with single dye,the combination dyeings in one bath have better UV protection performance,and FeSO_4 mordant dyeing can further improve the UPF values of the samples,which can reach up to 45.88.
