摘要
测量动态力学性质是研究高分子材料聚集态结构的重要方法之一。目前,用动态力学温度谱可对高分子材料改性的机理作定性分析。本文用温度谱求得松弛时间谱在一定程度上定量地反映出材料聚集态结构的变化规律,从而可说明热处理工艺对改善阳离子染料可染改性涤纶染色性的作用机理。
Mearsuring the dynamic mechanical properties is an important method of considering the aggregative structure of polymaterials. At present the dynamic mechanical temperature spectra are used to analysing the mechanism modification polymer material qualitatively. In this paper by means of the temperature spectra the relaxation time spectra is found,it is showed that the relaxation spectra can mirror the change of the regularity in the aggregative structure of the fibres quantitatively to a certain extent. By means of this technique the mechanism of improving the dye-ability of the fibres after heat setting is confirmed and illustrated more briefly.
