This paper deals with the alkali treatment affect for ramie yarn and ramie / cotton yarn in order to improve their elasticity. Predecessors pointed out that there are difference of yarn properties between the high tension and low tension for alkalization. Therefore this paper focuses on treatments under different tension. The results have shown that the breaking elongation of ramie yarn and ramie/cotton yarn is increased, their initial modulus is decreased and elasticity recovery is increased significantly.
