An uniaxial stretching was conducted by swell-wet stretching process in three different swelling agents (DMI, DMF, DMSO) to investigate stretching effect for indrawn aramid fiber (Technora) . The degree of swelling was increased with concentration of swelling agent and the most suitable concentration and treating time were 70% and 20 min., respectively. The breaking stress of aramif fiber was slowly decreased with concentration of swelling ;igent, but breaking strain was increased to the concentration 709 and decreased above. The result of stretching treatment for aramid fibers was showed that the orientation of fine structure, tensile strength and Young's modulus were increased with increasing drawing ratio, meanwhile breaking elongation was an opposite trend.
