Hemicellulose as a bio-based reinforcement for bamboo Lyocell fiber: A strategy for suppressing fibrillation and enhancing mechanical performance

• Bio-based hemicellulose used to suppress fibrillation in bamboo Lyocell fiber. • PAA pretreatment enables controlled retention of intrinsic hemicellulose. • Controlled hemicellulose incorporation improves fiber structural integrity. • Improved fibrillation resistance observed under mechanical stress conditions. • Sustainable approach without synthetic additives for durable textile applications.
