摘要

本研究的重点是可持续地利用藜麦植物成分,特别是其叶子,将其作为一种废弃的农业材料用于天然染色。研究人员选择了两种不同的藜麦基因型,即 Titicaca 和 Giza,以了解它们的天然染色特性。藜麦着色剂提取物的紫外-可见吸收光谱可帮助我们深入了解其化学成分,揭示出表明甜菜碱(400-450 纳米)、叶绿素(600-650 纳米)、类胡萝卜素(400-500 纳米)和芳香族氨基酸(250-280 纳米)的独特峰值。用不同植物部分(如花、叶和茎)染色的羊毛样品呈现出明显的黄色,其中叶片的着色强度最高。硫酸铁 (II)、硫酸铜和氯化锡 (II) 等金属媒染剂影响了染色结果,突出了它们在定制最终外观中的作用。对染色羊毛样品的牢度特性进行了评估,结果显示羊毛叶片具有适度的耐沾污性和良好的耐光牢度。此外,还对吉萨藜麦品种叶片的抗菌特性进行了评估,结果表明叶片对金黄色葡萄球菌具有良好的抗菌活性。用不同的金属盐媒染剂,特别是铁盐、铬盐和铜盐,通过媒染法将叶片提取物染色的织物的抗菌性能显著增强。这些结果凸显了藜麦植物成分在可持续天然染色和纺织品应用中的多方面益处,强调了它们在纺织业生态友好实践中的潜力。

Optimizing dyeing parameters for sustainable wool dyeing using quinoa plant components with antibacterial properties

This study focuses on the sustainable utilization of Quinoa plant components, particularly its leaves, as a waste agricultural material for natural dyeing applications. Two distinct Quinoa genotypes, Titicaca and Giza, were selected for their natural dyeing properties. UV-VIS absorption spectra of Quinoa colorant extracts provided insights into their chemical composition, revealing distinctive peaks indicative of betalains (400–450 nm), chlorophyll (600–650 nm), carotenoids (400–500 nm), and aromatic amino acids (250–280 nm). Wool samples dyed with different plant parts such as flowers, leaves, and stalks exhibited distinct yellow hue, with leaves demonstrating the highest color strength. Metal mordants such as iron (II) sulphate, copper sulphate, and tin (II) chloride influenced color outcomes, highlighting their role in tailoring final appearance. Fastness properties of dyed wool samples were evaluated, with leaves showing moderate staining resistance and good light fastness. Additionally, antibacterial properties of leaves of Giza Quinoa variety were assessed, showing promising activity against Staphylococcus aureus. The antibacterial properties of fabrics dyed with the leaf extract by mordanting method with different metal salt mordants, particularly Fe, Cr, and Cu, exhibited significant enhancement. These results highlight the multifaceted benefits of Quinoa plant components in sustainable natural dyeing and textile applications, emphasizing their potential for eco-friendly practices in the textile industry.
