Antimicrobial Activity of Natural Dyes – A Comprehensive Review

ABSTRACT

The increase in environmental consciousness and the pollution issues raised by the textile industries take natural dyes from back to the front stage. The trend of the textile industry shows a gradual change from fashion to functional apparel and healthy lifestyles. Since cotton is the most preferred natural fiber for the apparel industry, most of the research attempts had been done to overcome the inherent drawbacks of poor bacterial and UV resistance. The natural dyes are loaded with an abundant amount of phytochemicals, which provide characteristic functional finishing to the textiles. This paper reviews the scientific efforts done in the field of natural dyes for obtaining antimicrobial activity. The principal phytochemicals responsible for color, antimicrobial and antifungal activity, their mode of action, method of application, and evaluation of bacterial resistance, challenges, and market potentials are also attempted to cover at the maximum possible extent.

摘要

环境意识的增强和纺织工业所带来的污染问题，使天然染料从落后走向了前台. 纺织业的发展趋势是由时尚向功能性服装和健康生活方式的逐步转变. 由于棉花是服装工业中最受欢迎的天然纤维，大多数研究尝试都是为了克服固有的缺点，即细菌和紫外线抗性差. 天然染料中含有大量的植物化学物质，为纺织品提供了独特的功能性整理. 本文综述了近年来在天然染料领域为获得抗菌活性所做的科学努力. 本文还尽可能地介绍了植物化学物质的主要颜色、抗菌和抗真菌活性、作用方式、应用方法、细菌抗性评价、面临的挑战和市场潜力.
