In this study, we prepared long-persistent luminescent strontium aluminate/cotton compound fabric using green tea natural dye and evaluated its functional properties. Green tea natural pigments were extracted at different extraction temperature, extraction time, and bath ratio. We determined the optimum parameters of the technique by comparing the absorbance. The dyeing rate and UV protection of the strontium aluminate particles dip-coated compound textile were optimized using the response surface methodology (RSM). The results indicated that the dye-uptake of the sample was significantly different. However, the UV protection property was not significantly different. The dyeing time was the most significant factor influencing dye-uptake. Optimum dyeing effect and UV protection (K/S value = 1.6621 and UPF value = 38.581, respectively) were attained at a dyeing temperature of 89.92 °C, the dyeing time of 67.06 min, and bath ratio of 42.28. The compound fabric dyed using in-bath mordant and dip-coated with strontium aluminate phosphor exhibited long-persistent luminescence property that was effective for 120 min.

在这项研究中，我们使用绿茶天然染料制备了持久发光的铝酸锶/棉复合面料，并评估了其功能特性。绿茶天然色素是在不同的提取温度，提取时间和浴比下提取的。我们通过比较吸光度确定了该技术的最佳参数。使用响应表面方法（RSM）优化了铝酸锶颗粒浸涂复合纺织品的染色速度和紫外线防护。结果表明样品的染料吸收显着不同。但是，紫外线防护性能没有显着差异。染色时间是影响染料吸收的最重要因素。最佳的染色效果和紫外线防护（K / S值= 1.6621和UPF值= 38.581，分别在89.92°C的染色温度，67.06分钟的染色时间和42.28的浴比下达到。使用浴媒染液染色并浸涂铝酸锶磷光体的复合织物表现出可持续120分钟的长效发光性能。
