Sustainable Functional Coloration of Linen Fabric Using Kigelia Africana Flower Colorant

ABSTRACT

Natural dyes are gaining momentum in the textile industry due to their non-toxic and eco-friendly nature. The enhanced demand of natural-dyed functional textile materials resulted in increased interest among the research community to explore new sources of natural dyes which could be utilized for functional coloration of textile materials. Kigelia Africana flower is known for various medicinal properties and thus can be utilized for functional coloration of textile materials. In the current study, the pre-mordanting process has been exploited to evaluate the dyeing condition of the linen fabrics by using different mordants such as; alum, ferrous sulfate, and copper sulfate. The effect of mordants on the color strength of the dyed fabrics was analyzed and correlated with wash fastness tests results. The dyed fabrics analysis has been carried out in terms of their color strength and color coordinates (L*a*b*). The functional properties like radical scavenging activity, antibacterial activity, and UV protection properties were thoroughly investigated to determine the functionality of dyed fabrics. The dyed samples displayed satisfactory fastness and color strength along with efficient antibacterial, antioxidants and UV protection properties.

摘要

天然染料以其无毒、环保的特性在纺织工业中得到了发展. 对天然染色功能性纺织材料的需求增加，使得研究界对探索可用于纺织材料功能性染色的天然染料的新来源越来越感兴趣. 非洲基格里亚花以其多种药用特性而闻名，因此可用于纺织材料的功能性着色. 在目前的研究中，我们利用预媒染剂工艺，通过使用明矾、硫酸亚铁和硫酸铜等不同的媒染剂来评估亚麻织物的染色条件.分析了媒染剂对染色织物色强度的影响，并与耐洗性试验结果进行了关联. 根据染色织物的颜色强度和颜色坐标（L*A*B*）进行了染色织物分析. 对染色织物的清除自由基活性、抗菌活性、防紫外线性能等功能性进行了深入的研究，以确定其功能性. 染色后的样品显示出令人满意的牢度和色强度，以及有效的抗菌、抗氧化剂和紫外线防护性能.
