Antibacterial Functionalization and Simultaneous Coloration of Wool Fiber with the Application of Plant-Based Dyes

ABSTRACT

High susceptibility of wool toward bacterial growth owing to proteinous nature and moisture retention ability leads to need for antibacterial functionalization of wool to cure the resulting deterioration. Antibacterial colored wool was designed via application of Terminalia chebula, Alkanna tinctoria, and Tagetes erecta natural dyes. Characteristics in terms of color and antibacterial activity were compared to correlate coloring compound’s effect on characteristics of dyes and, both T. chebula and A. tinctoria dyes inferred themselves actively resisting bacterial growth while T. erecta was not efficient against bacterial strains. Colorful shades of good color and fastness properties were obtained from selected natural dyes on woolen yarn. Results show Bacillus subtilis and Staphylococcus aureus (gram positive) were highly resisted by the effect of T. chebula and A. tinctoria dyes, and T. chebula among them proved best in terms of both color characteristics and antibacterial potential.

摘要

由于蛋白质性质和保湿能力，羊毛对细菌生长的高易感性，导致需要羊毛的抗菌功能化以治愈由此导致的劣化。通过应用诃子、石楠和天然染料，设计了抗菌彩色羊毛。颜色和抗菌活性方面的特征进行比较，以关联着色化合物对染料的特性的影响，T.诃伯和A.tinctoriadyes推断自己积极抵抗细菌生长，而T. erecta对细菌菌株不有效。从羊毛中选择的天然染料获得了色泽鲜艳、牢度好的色泽。结果表明，诃子和A.tinctoriadyes对枯草芽孢杆菌和金黄色葡萄球菌（革兰氏阳性菌）有较强的抗性，其中T.诃属在颜色特征和抗菌潜力方面表现最好。
