research was to synthesize some new dye molecules with embedded UV-protection properties. Structure elucidation of these dye molecules was carried out using FTIR, UV–visible spectrophotometry, 1H-NMR spectroscopy, and Mass spectrometry which confirmed the chemistry of target molecules. The resultant dye molecules were applied on silk and wool fibers and their fastness properties were studied through ISO
本研究的主题是合成一些具有嵌入式紫外线防护特性的新染料分子。使用 FTIR、紫外-可见分光光度法1对这些染料分子进行结构解析H-NMR光谱和质谱证实了目标分子的化学性质。将所得染料分子应用于丝绸和羊毛纤维,并通过 ISO 推荐的方法研究其牢度特性。染料表现出令人满意的吸尽和固色效率,并表现出良好的抗褪色性。评估染料溶液的吸收特性以分析染料分子的抗紫外线能力。还检查了染料在紫外光下的稳定性。测量染色样品的紫外线防护系数 (UPF) 以检查染料在应用后的紫外线阻挡能力,并将染料的防护性能与商业酸性染料 (Nylosan Red S-GS) 进行比较。
