Development of Mosquito Repellent, Antibacterial, Antioxidant and UV Protective Cotton Using a Novel Method of Azoic Dyeing with Terminalia Chebula

ABSTRACT

With rising awareness regarding human and environmental safety, the use of sustainable resources for the functionalisation of natural textile fibers are highly demanded. The present study investigates a novel process for the development of multifunctional cotton using the azoic dyeing method. Preparation of azoic dyes was performed using ethyl anthranilate (EA), a safe mosquito-repellent, and Terminalia chebula natural dye as the coupling component. The novel method of in-situ azoic dyeing using Terminalia chebula and ethyl anthranilate for functional coloration of cotton is explored. The developed shades were found satisfactory in terms of fastness and color strength. The novel method resulted in mosquito-repellent cotton with 100% mosquito repellency, which was found durable until at least 20 washes. Additional functional properties such as antibacterial activity (more than 94%), antioxidant activity (>87%) and UV protection (UPF >50) were also confirmed.

摘要

随着人们对人类和环境安全意识的提高, 对利用可持续资源实现天然纺织纤维功能化的要求越来越高. 本研究探讨了一种利用偶氮染色法开发多功能棉的新工艺. 以安全的驱蚊剂邻氨基苯甲酸乙酯 (EA) 和诃子天然染料为偶联剂, 制备了偶氮染料. 探索了用诃子和邻氨基苯甲酸乙酯对棉进行原位偶氮染色的新方法. 开发的色调在牢度和色强度方面令人满意. 这种新方法产生了100%驱蚊效果的驱蚊棉, 这种棉至少可以洗20次. 其他功能特性如抗菌活性 (超过94%) 、抗氧化活性 (>87%) 和紫外线防护 (UPF>50) 也得到了证实.
