摘　　要：研究了PTT长丝的力学性能和热性能,并与其他长丝进行了比较,结果表明PTT长丝具有优良的弹性和柔软度,其断裂伸长和弹性回复性比其他长丝好。经过热处理的PTT长丝的断裂伸长率增大,但断裂强度和弹性回复性都降低。The article studies the mechanical and thermal properties of PTT filament by comparing it with other filaments. The result shows that PTT filaments is of good elasticity and softness with its breaking elongation and elastic recover rate higher than that of other filaments, especially PET. After heat treated, its breaking elongation increases whilst its breaking intensity and elastic recover rate decreases.
