摘要
为了研究SF固色剂在染色中应用的条件,使用紫外分光光度计和激光粒度仪,分析了SF固色剂与染料在不同条件下反应前后的变化;然后将这种固色剂应用于皮革染色过程中,并分析革坯的理化指标。试验结果表明:随着反应温度的升高、反应时间的延长和SF固色剂用量的增加,SF固色剂与染料反应后,体系的Zeta电位明显降低,平均粒径显著增大,体系中染料残留量大幅降低,说明SF固色剂可以与染料发生较强的反应。该固色剂用于固色所得革坯的油脂含量高,颜色坚牢度、鲜艳度和饱和度均有提高。
In order to study the application conditions of the color - fixing agent in dyeing process, the UV/VIS and dynamic laser light scattering were used for analyzing the changes of reaction between dyestuff and the color - fixing agent under different conditions, and the chemical and physical properties of dyed leathers were tested. The results show that the Zeta potential and dye- stuff residue of system are decreased and the average particle size is increased with the increase of temperature, reaction time and dosage of color- fixing agent, which indicate that color- fixing agent reacts strongly with dyestuff. The results also show that the oil content, color fastness, brightness and saturation of leather are improved after fixed by SF color - fixing agent.
