摘要/Abstract

摘要： 利用功能性荧光染料5(6)-(4,6-二氯三嗪基)氨基荧光素（DTAF）对棉织物进行染色，考察了染色浓度、固色温度对染色后织物K/S值的影响，并系统研究了在不同染色浓度下，染色织物的K/S值、反射率曲线、荧光发射光谱的变化规律及相互关系。实验结果表明：随着染色浓度的增加，染色织物的反射率曲线、荧光发射光谱均发生红移；染色织物的最大反射率值及荧光强度均随织物上染料量的增加呈现先增后减的趋势。当染色浓度为0.1%（o.w.f）时，染色织物的最大反射率值可达到130%。此外，DTAF可明显改善纯棉织物的抗紫外线性能，当染料染色浓度大于或等于1%(o.w.f)时，其染色织物的UPF等级可达到50+，具有优异的抗紫外线功能。

Abstract: The functional fluorescent dye 5(6)-(4,6-Dichlorotriazinyl)aminoFluorescein was used for dyeing cotton fabrics. The effect of dye concentration and fixing temperature on the K/S value of dyed fabrics was studied. The changing of K/S value, the moving of reflectance curve and fluorescence emission spectra as the change of dyeing concentration were investigated, and the relationship among the max reflectance, fluorescent intensity and K/S value was discussed. The results indicated that as the dye concentration increased, the red-shifting of reflectance and fluorescence emission spectra of dyed fabric was found. As the K/S value keeps increasing, the maximum emission wavelength and the fluorescence intensity of dyed fabric increases first then starts to drop. When the dye concentration was 0.1% ( o.w.f ), the maximum reflectivity of dyed fabric can reach 130%.DTAF can greatly improve the anti-ultraviolet performance of cotton fabrics. When the dyeing concentration is equal to or greater than 1% (o.w.f), the UPF value of dyed fabric can reach 50 +.
