Lignin Extraction from Jute Fabric and its Dynamic Influence on Reactive Dye Affinity

---

Abstract

This study explores the impact of partial lignin extraction on jute fabric and its affinity for reactive dyes. Jute, a biodegradable and eco‑friendly fiber, is often limited in apparel use due to its stiffness and rough texture caused by lignin. Through chemical treatment with hydrogen peroxide and sodium hydroxide, lignin content was reduced, resulting in increased cellulose exposure and improved softness. Three fabric samples including bleached jute, cotton, and lignin‑reduced jute were dyed under identical conditions using reactive dyes. Physical testing revealed that lignin‑reduced jute maintained higher tensile strength than cotton, though abrasion resistance decreased. SEM and FTIR analyses confirmed structural modifications, including expanded fiber diameter and altered functional groups. Colorfastness tests indicated moderate dye affinity, with lignin‑reduced jute showing enhanced bonding to cellulose hydroxyl groups. Findings suggest that lignin extraction improves jute’s dyeability and comfort, positioning it as a sustainable, cost‑effective alternative.

Keywords: Jute, lignin extraction, reactive dye, affinity, sustainability.
