摘　　要：采用广玉兰叶色素对半漂棉布和阳离子改性棉布进行吸附试验,测试了吸附色素前后棉布的UPF值,探讨了布种、广玉兰叶色素体积、吸附液pH、浴比、吸附温度、吸附时间对棉布UPF值的影响。结果表明:阳离子改性棉布4 g、广玉兰叶色素体积90 mL、吸附液pH 9、浴比1∶40、吸附温度80℃、吸附时间60 min的条件下,广玉兰叶色素染色阳离子改性棉布的UPF值达278。The adsorption of colorants extracted from magnolia grandiflora leaves on semi-bleached cotton cloth and cationic modified cotton cloth is studied.The UPF values of cotton cloth before and after adsorption of colo⁃rants are tested,and the effects of cloth type,dye volume,pH value of dye solution,bath ratio,adsorption tem⁃perature and time on UPF values are discussed.The results show that:under the conditions of 4 g cationic modified cotton cloth,90 mL dye solution,pH 9 of dye bath,1∶40 of bath ratio,adsorption temperature 80℃and adsorption time 60 min,the UPF value of cationic modified cotton cloth can reach 278.
