【摘要】 荧光增白剂通过吸收紫外光与发射可见光,使织物增白和增艳。针对荧光增白剂的光吸收特性及光反射特性与浓度的关系,通过对荧光增白染色样和荧光增白坯布样进行一系列试验及系统测试,提出了从总反射率中分离出荧光增白剂的吸收与发射部分的方法,获得了定性和定量的重要结果,为含荧光增白剂染色样的计算机测配色奠定了基础。更多还原

【Abstract】 Through the absorption of UV and reflection of visible light, fluorescent brightening agents(FBA) can enhance the whiteness and brightness of fabrics. Based on a series of whitening experiments on undyed and dyed fabrics and their measurements of reflectance,the relationship between absorption and reflection of light and the concentration of FBA is analyzed in this paper. Some qualitative and quantitative results are obtained so as to lay the foundation of computer colour matching(CCM) of FBA.更多还原
