Abstract

The elasticity and broken strength and elongation of the PTT fiber and PTT/wool blended yarns under different temperature and tension are investigated.The heat treatment under no tension will lower the initial modulus and improve the broken elongation ratio of PTT fiber.The tension on the PTT fiber will prevent the initial modulus lowering when the fiber is treated in higher temperature.The elasticity of the PTT fiber will be improved when the fiber is in 150 ℃ and with the tension of 6 cN/tex.These phenomenons are also proven in the experiments of the PTT/wool blended yarns.
