ABSTRACT

There is a growing literature investigating to use natural materials for dyeing textiles on account of their low toxicity, eco-friendliness, sustainability, and better biodegradability. In this way, this article presents the results of a study into the applications of tamarind hull and marzangoosh in a fully eco-friendly manner to dye cotton yarns. The effect of the main dyeing conditions (dye concentration, bath pH, time, and temperature) on the color efficiency (K/S) was investigated with a reflectance spectrophotometer. Results indicate that at optimized conditions, pre-mordanting yarns with tamarind hull as an eco-friendly mordant lead to the formation of an insoluble complex on cotton yarns followed by increased dye adsorption, which enhances the light and wash fastness properties. The SEM photographs showed that pre-mordanting cotton yarns with tamarind hull increase the surface porosity. Finally, based on our observations, it may be claimed that cotton yarns subjected to both pre-mordanting and dyeing exhibited a good antibacterial activity and the procedure proposed in this study seems to be of potential use for the production of medical textiles without adverse environmental impacts.

摘要

越来越多的文献研究使用天然材料对纺织品进行染色，因为它们具有低毒、环保、可持续性和更好的生物降解性。通过这种方式，本文介绍了以完全环保的方式应用罗望子壳和 marzangoosh 染色棉纱的研究结果。主要染色条件（染料浓度、浴液pH、时间、温度）对色效（K/S ）的影响) 用反射分光光度计研究。结果表明，在优化条件下，罗望子壳作为环保媒染剂的预媒染纱线会在棉纱线上形成不溶性复合物，从而增加染料吸附，从而提高耐光和耐洗牢度性能。SEM 照片显示，带有罗望子壳的预媒染棉纱增加了表面孔隙率。最后，根据我们的观察，可以声称经过预媒染和染色的棉纱表现出良好的抗菌活性，并且本研究中提出的程序似乎可用于生产医用纺织品而不会产生不利的环境影响.
