摘　　要：为更好地开发新型PTT纤维面料,在不同拉伸比和温度下对PTT织物进行热定型.研究了热定型工艺对PTT织物服用性能的影响,采用XRD从微观上分析了热定型对纤维结晶形态的影响.结果表明：PTT织物的断裂强力随热定型温度的升高和拉伸比的增大有增加的趋势,弹性回复性随温度升高呈上升的趋势,柔软性则随温度的升高和拉伸比的增大变差;不同的热定型工艺对纤维的结晶形态有影响;在拉伸比约为5%,150～170℃左右热定型,能改善PTT织物的服用性能.In order to develop new fabrics involving PIT fiber, the heat settings of PIT fabrics with different elongation under different temperatures were carried out. The influence of heat setting process on the performance of PIT fabrics was investigated. The XRD analysis was used to characterize the changes of crystallinity within the fiber influenced by heat setting. The experimental results showed that the strength and elasticity recovery ratio of PTT fabrics basically increased with rising of the temperature and increase of the fabric elongation, while the softness became worse. The crystallinity of PIT fiber was found being changed by the heat setting. In conclusion, the heat setting around 170 ℃ with an elongation of about 5% would helpful in improving the performance of PTT fabrics.
