Abstract

Purpose

This paper aims to focus on the aqueous extraction of natural dye from haematoxylum campechianum L. bark for finishing the bio-mordant cotton fabrics producing value-added, environment-friendly textile products, for biomedical applications.

Design/methodology/approach

The study focuses on the creation of eco-friendly bio-mordant cotton fabric using gallic acid and gelatin, Al³⁺ and Fe²⁺ salts and metal mordant. The optimal pH for extraction, structural characterization and phytochemical analysis of the extracted dye were estimated using UV-visible spectrophotometer, FTIR and qualitative analysis. Variations in electrolyte concentration and pH medium were also considered. The study also examines build-up properties, colorimetric values and fastness characteristics of the colored fabrics.

Findings

All the dyed fabrics exhibit very good to excellent in terms of antimicrobial resistance against S. aureus and C. allbicans.

Practical implications

Pre-mordant cotton fabrics with Fe²⁺ and a combination of metal and bio-mordant show higher antibacterial resistance against P. aerugionsa. Further, bio-mordant and a combination of both mordant exhibit excellent UV protection and antioxidant activity performance compared to that of undyed fabrics.

Originality/value

This work opens up a huge potential for producing healthy bioactive-colored fabrics used in medical textiles and other usages.

一种利用haematoxylum campechianum L.树皮对棉织物进行功能性整理和着色的简便方法

设计/方法/途径该研究的重点是使用没食子酸和明胶、Al3+ 和 Fe2+ 盐以及金属媒染剂制作生态友好型生物媒染棉织物。使用紫外-可见分光光度计、傅立叶变换红外光谱仪和定性分析估算了萃取的最佳 pH 值、萃取染料的结构特征和植物化学分析。还考虑了电解质浓度和 pH 介质的变化。研究结果所有染色织物对金黄色葡萄球菌和白色念球菌的抗菌性都非常好，甚至非常出色。此外，与未染色织物相比，生物媒染剂和两种媒染剂的组合具有出色的防紫外线和抗氧化性能。
