Abstract

Abstract:

In view of the high price of optically variable pigments, lack of chromatogram, poor color fastness of printed fabrics, and stiff hand feel, etc., the basic characteristics of the optically variable pigments and the printing process of disperse dyes/optically variable pigments in the same slurry are studied systematically to broaden the chromatography of optically variable pigments, and a controllable multi-tone photochromic printed fabric is developed. The results show that the Mc-series optically variable pigments have an obvious discoloration effect, excellent sensitivity and fatigue resistance. The multi-tone photochromic printing process developed is: a mass fraction of the optically variable pigments of 6%, a proper quantity of disperse dyes, a ratio of the adhesives TF-321G to TF-3201 of 2:1, a mass fraction is 6%, a mass fraction of the thickener TF-321F of 1.2%, a baking temperature of 170℃, and a baking time of 4 min. With different color tones and dosages of the disperse dye, the chromatogram of printed fabrics has been expanded.

Key words: optically variable pigments, same-size printing, control, multi-tone, photochromic fabric

摘要：

针对当前光变颜料价格昂贵、色谱欠缺,印花织物色牢度较差、手感僵硬等问题,系统研究了光变颜料的基本特性以及分散染料/光变颜料同浆印花工艺,拓宽了光变颜料色谱,研制开发了可调控的多色调变色印花织物。结果表明:Mc-系列光变颜料变色效果明显,且灵敏度和耐疲劳度优良;研制的多色调光致变色印花工艺为:光变颜料质量分数为6%、分散染料适量、黏合剂TF-321G与TF-3201比例为2:1且质量分数为6%、增稠剂TF-321F质量分数为1.2%,焙烘温度170℃、焙烘时间4 min;随着分散染料色光和用量的不同,印花织物的色谱得到了拓展。
