Ecology of environmental materials (cloths and life materials) and physical protection using functional UV cutting materials

为了提高紫外线吸收剂的紫外线防护因子（UPF），改善染色织物的耐光牢度，合成了不同类型的含苯并三唑基的二苯甲酮或苯并三嗪类紫外线吸收剂。 用多种方法研究了它们的紫外-可见吸收光谱、对染料褪色的抑制作用和抗菌活性。 结果表明，新化合物具有很高的UPF，对提高染料的耐光牢度有重要作用。此外，这些稳定剂也被认为对环境和人类健康安全。

Various kinds of benzophenone or benzotiriazine UV absorbers bearing benzotriazolyl groups were synthesized in an attempt to increase the Ultraviolet Protection Factors (UPF) of UV absorbers, and improve the light fastness of dyed fabrics. Their ultraviolet-visible absorption spectra, inhibiting effect on the fading of dyes and antibacterial activity of new stabilizers was examined in various methods. It was found that new compounds show very high UPF, and play an important role in improving the light fastness of dyes. Moreover, these stabilizers were also deemed safe for environment and human health.
