To clarify the effect of alkali-treatment on the mechanical properties of plant-based natural fibers, ramie plied yarns were treated using NaOH solution. The alkali-treated yarns decrease in strength if the concentration of the solution is more than 15wt%. It was proved from X-ray analysis that this decrease was closely related with the change in crystallinity index of the yarns. Such change in strength properties was similarly seen in green composites reinforced with the same yarns. Furthermore, in this study, the effects of liquid ammonia treatment on the mechanical properties of ramie plied yarns and their green composites were investigated.
