Application of Eugenol-derived azo dyes on natural textile fabrics
| Resumo: | Eugenol, a natural product abundant in clove oil, represents a promising precursor for the synthesis of azo dyes, proving potential for textile coloration. The eugenol azo dyes were synthesized and characterized, showing stable absorption profiles across a wide pH range. Their application to cotton and wool knitted fabrics by exhaustion dyeing demonstrated good affinity, particularly for wool, while chitosan pretreatment improved washing fastness in cotton. These eugenol-derived azo dyes emerge as promising candidates for sustainable textile coloration. |
