The results showed that the breaking 30 35 40 strength of ramie fabric was decreased seriously caused by cellulase finishing instead of reducing prickle sensation effectively. The hairiness on ramie fabric surface is partly softened or removed by appropriate cellulase finishing, and benificial to consequent polyurethane finishin. However, the decrease of prickle sensation is limited by this cellulase finishing. Polyurethane finishing of ramie fabrics decreased fabric prickle property remarkably, due to the improvement in fabric surface smoothness and the decrease in the surface hairiness by wrapping and sheathing ramie fibers or yarns. Meanwhile, the compressive property of ramie fabrics was effectively increased by cross-linking
