| 摘 要： | 本文通过模拟纤维使用过程中所经历的光照、氧化和还原等环境作用因素，用紫外光谱的方法研究了几种染料的化学结构的变化，其中光化学变化、氧化还原烟气(NO2、H2S等)作用是影响染料老化的几个重要因素之一，光化学作用是使染料发生化学变化(如偶氮键断裂)的主要因素。

| Abstract: | Several dyes were studied by exposing them to conditions that imitate environmental factors that affect fibers during application, such as light exposure, oxidation and reduction. Chemical structural changes in the dyes were then examined by UV. It was found that photochemical changes and the effects of oxidative and reductive gasses (NO2, H2S, etc.) were the main factors affecting dye degradation on fibers, and that photochemical effects were the primary factor leading to chemical changes (such as breaking azo bonds) in the dyes. |
