摘要

This study explores utilization of coffee leaves extract for development of UV-resistant cotton fabric which is consider as an underutilized agricultural by-product. The research aims to provide an eco-friendly alternative to synthetic UV-blocking agents by optimizing dye extraction and mordanting conditions. The dyed fabrics exhibited significant enhancements in UV protection, tensile strength (154.17 N warp, 103.95 N weft), thickness (0.236 mm), drapability (122.17%), moisture regain (13.65%), and air permeability (26.20 cm³/cm²/s). Structural modifications were confirmed via Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX), and X-ray Diffraction (XRD). Among mordants, copper sulfate-treated fabrics demonstrated the highest UPF value of 90, confirming their superior UV-blocking capability and myrobalam is also considered as natural mordant suitable for coffee leaves extract. This study highlights the potential of repurposing coffee leaf waste in textile applications, contributing to sustainable and bio-based UV protection solutions.
