摘要 在实验条件下,染色织物的荧光反射率随荧光染料的浓度增加而增加,超过一定浓度后,有下降趋势;在pH=5左右,荧光反射率最高:荧光增白剂会提高染色织物的荧光反射率,在荧光黄2GFL中,当荧光增白剂的浓度由0.1%增加到5%时,荧光反射率由8.43增加至18.59,而对非荧光染料只有增艳的作用,不产生荧光。荧光染料染色织物的荧光反射率随着加入非荧光染料量的增加而减弱。 Under the experimental conditions, the fluorescence reflectance of fabrics improved with the increase of the concentration of fluorescent dyes, but it showed downtrend over a certain concentration; the fluorescence reflectance was the highest at about pH = 5; The fluorescence reflectance of dyed fabrics was improved by fluorescence brightening agent (FBA), when the concentration of FBA in Fluorescent Yellow 2GL was increased from 0.1% to 5%, the fluorescence reflectance was improved from 8.43% to 18.59%, FBA only improved the brightness of non-fluorescent dyes, and no fluorescence was observed, the fluorescence reflectance of fabrics dyed with fluorescent dyes was lowered with the adding of non-fluorescent dyes.
