In this research paper, an eco-friendly extraction process of dyes from Vicia faba L. membranes was developed. In this regard, the influence of independent process factors like the weight of material, the extraction time, the temperature and the sodium hydroxide concentration on the natural dye extraction from Vicia faba membranes was investigated. The optimisation of the extraction conditions and the effect evaluation of the different operating parameters were carried out using a Box-Behnken design under response surface methodology. The optimum conditions were found to be 66 °C, 90 min, 5 g and 0.1628 mol·L for extraction temperature, time, mass of the material and sodium hydroxide concentration, respectively. The efficiency of this extraction process under these optimum conditions was evaluated by measuring the total phenolic content (TPC), the total flavonoid content and the relative colour yield (K/S). In these operating conditions, good fastness ratios were observed for the dyed fabrics.
在本研究论文中，开发了一种从蚕豆膜中提取染料的环保工艺。在此方面，研究了诸如物料重量、提取时间、温度和氢氧化钠浓度等独立工艺因素对从蚕豆膜中提取天然染料的影响。使用响应面法下的Box-Behnken设计对提取条件进行了优化，并对不同操作参数的效果进行了评估。发现提取温度、时间、物料质量和氢氧化钠浓度的最佳条件分别为66℃、90分钟、5克和0.1628摩尔·升。通过测量总酚含量（TPC）、总黄酮含量和相对色深（K/S）来评估在这些最佳条件下该提取工艺的效率。在这些操作条件下，观察到染色织物具有良好的色牢度比率。
