In this research article, it is reported the preparation and characterisation of four types of blended cotton-polyester based textile materials in different dye ratios with four kinds of natural dyes of agro waste (walnut shell, onion peel) and wildflowers (tansy, Hypericum) with/without mordants as antibacterial and antifungal species for shoe materials. The dyed samples were spectrophotometrically measured and the results were obtained as colour strength (K/S) as well as CIELab values. As a result, dyed fabrics with natural dyes showed yellow, grey, orange and brown colours. With the help of a mordant, aluminium-potassium, the dyed fabrics obtained natural, not distorted shades of these colours, and with the addition of copper sulphate, they showed changing yellow to light green, orange to dark red, grey to a darker shade of grey and brown to a darker colour. The dyed samples were tested for colour fastness to circle rubbing and satisfactory results were found. The fabrics dyed only with natural dyes and treated with natural dye and mordants were evaluated for antibacterial and antifungal properties against Escherichia coli, Staphylococcus aureus, and Candida albicans. The results indicated that fabrics treated with these natural dyes and mordants had excellent antibacterial and antifungal activity. All natural dyes and mordants used in this study were the most effective and showed the maximum inhibition zone, indicating the best antimicrobial and antifungal activity against tested microbes. The results showed that all these natural dyes can provide some antibacterial and antifungal activity on mixed fabrics.

植物染料和媒染剂处理混纺织物作为鞋材的染色、抗菌和抗真菌性能研究

在这篇研究文章中，报道了以农业废弃物（核桃壳、洋葱皮）和野花（艾菊、金丝桃）四种天然染料为原料，以不同染料配比制备四种棉涤混纺纺织材料并对其进行表征。含有/不含媒染剂作为鞋材的抗菌和抗真菌物种。对染色样品进行分光光度测量，结果以颜色强度（K/S）以及 CIELab 值。结果，用天然染料染色的织物呈现出黄色、灰色、橙色和棕色。在媒染剂铝钾的帮助下，染色的织物获得了这些颜色的自然、不扭曲的色调，并且随着硫酸铜的添加，它们呈现出黄色变为浅绿色、橙色变为深红色、灰色变为更深的色调灰色和棕色到更深的颜色。测试染色样品的耐圈摩擦色牢度，结果令人满意。仅用天然染料染色并用天然染料和媒染剂处理的织物被评估对大肠杆菌、金黄色葡萄球菌和白色念珠菌的抗菌和抗真菌性能。。结果表明，用这些天然染料和媒染剂处理的织物具有优异的抗菌和抗真菌活性。本研究中使用的所有天然染料和媒染剂都是最有效的，并显示出最大的抑制区，表明对测试微生物具有最佳的抗菌和抗真菌活性。结果表明，所有这些天然染料都能在混合织物上提供一定的抗菌和抗真菌活性。
