| 摘 要： | 本文研究了不同拉伸温度、不同拉伸比ＰＢＴ纤维的热行为和力学性能．ＤＳＣ结果表明：ＰＢＴ纤维的Ｔｇ在恒定温度下，随拉伸比的坤加而升高．当拉伸比低于４、０时，随拉伸温度的升高，ＰＢＴ纤维的Ｔｇ降低，当拉伸比大于３．０时，ＰＢＴ纤维的Ｔｇ随拉伸温度升高而升高，拉伸温度对ＰＢＴ纤维的初始模量及抗很强度的影响呈现出与上述相似的规律性．

| Abstract: | In this paper,thermal behavior and mechanical property of PBT fiber at different draw ratio have been studied.The result of DSC have indicated with at con-stant temperature, Tg of IJBT fiber increased with draw ratio. when draw ratio is lower than 4.0,Tg of PBT fiber deoreastred with draw temperature,however,when draw ratio is higher than 3.0,Tg of fiber increpsed with draw temperature. the influ-en of draw ratio on initial modulus and stress at break had demonstrated the same regular law as mentioned abovee. |
