Natural dyes are gaining importance in textile dyeing applications in recent years due to the fact many synthetic dyes are carcinogenic, mutagenic, and allergic. In this study, cotton knitted fabrics were dyed with extract solutions of 40 different dye plants without the mordant usage. Afterwards color efficiency and fastness values of dyed samples were evaluated. Dye plants that are able to give good color efficiency with sufficient fastness values were determined. According to the experimental results it can be said that for yellow color pomegranate peel and turmeric; for red color madder and quince; for blue color indigo; for green color myrobalan; for brown color white onion peel and catechu give the optimum results. Furthermore, it was tested whether ultraviolet protection effect could be obtained via dyeing with white onion peel or turmeric and it was found that both of these plants gave very good UV protection functionalization to cotton fabrics.

由于许多合成染料具有致癌性，诱变性和过敏性，因此近年来天然染料在纺织品染色应用中变得越来越重要。在这项研究中，用40种不同染料植物的提取液对棉针织物进行了染色，而无需过度使用。之后，评估染色样品的颜色效率和坚牢度值。确定了能够以足够的坚牢度值提供良好的色彩效率的染料植物。根据实验结果，可以说是黄色石榴皮和姜黄；用于红色茜草和木瓜；用于蓝色靛蓝；用于绿色myrobalan；对于棕色，白洋葱皮和儿茶可以达到最佳效果。此外，
