Natural Dyes from Three Invasive Plant Species in The United States

ABSTRACT

Natural dyes from invasive plant species may serve as reliable, nontoxic, replicable alternatives to synthetic dyes. Novel approaches to invasive species control aids in restoration, incentivizes commercial uses, and results in large-scale removal with improved biodiversity. The purpose of the study was to test the dye effectiveness of three invasive plant species on organic cotton and wool for outdoor apparel in colorfastness to wet and dry crocking, perspiration, laundering, and antimicrobial action against Escherichia coli, Staphylococcus aureus, and Aspergillus Niger. Invasive plant roots used to dye were: Japanese barberry (Berberis thunbergii), wineberry (Rubus phoenicolasius), and oriental bittersweet (Celastrus orbiculatus). Mordants [Red oak acorn (Quercus rubra), acetate, and alum] expedited dyeing and fixation. Color intensity was measured using L*, a*, b*, and ∆E* values. Wool morphology produced better coloration. Barberry showed the most promising antimicrobial properties on cotton even though there was dye migration during wet crocking, perspiration, and laundering. The resulting earth tones and fabric weight are ideal for outdoor furniture or winter apparel.

摘要

来自入侵植物物种的天然染料可作为合成染料的可靠、无毒、可复制的替代品. 新的入侵物种控制方法有助于恢复, 刺激商业用途, 并导致大规模清除, 改善生物多样性. 本研究的目的是测试三种入侵植物对户外服装用有机棉和羊毛的染色效果, 包括耐干湿摩擦色牢度、汗渍、洗涤以及对大肠杆菌、金黄色葡萄球菌和黑曲霉的抗菌作用. 用于染色的入侵植物根有:日本小檗 (Berberis thunbergii) 、葡萄酒浆果 (Rubus phoenicolasisus) 和东方苦乐参半 (Celastrus orbillatus). 媒染剂[红橡子 (红栎)、醋酸盐和明矾]加速染色和固定.使用L*、a*、b*和∆E*值. 羊毛形态产生更好的着色. Barberry在棉花上表现出最有希望的抗菌性能, 尽管在湿摩擦、出汗和洗涤过程中染料会迁移. 由此产生的泥土色调和织物重量非常适合户外家具或冬季服装.
