摘要
对热处理的阳离子可染改性涤纶测得的动态力学温度谱,求得松弛模量,应力松弛谱以及WLF方程中的结构常数C1和C2,分析了试样超分子结构的变化,说明了热处理工艺改善纤维可染性的机理。
The relaxation modulus, the relaxation time spectra and the structure parameters C 1 and C 2 in the WLF equation were derived from the dynamic mechanical temperature spectra of the cationic dyeable PET fibres after heat setting. Furthermore, the changes in the super molecular structure of the samples are analysed and the mechanism of improving the dyeability of the fibres by heat setting process is suggested.
