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.
