在前文中发现,用乙二胺对涤纶织物进行氨解,然后再与糖-内酯反应,可使涤纶织物的亲水性大大提高,但前者易导致其机械强度下降。在这里,考察了氨解反应温度和胺的结构对机械强度和吸附在其上的水蒸气的影响。因此,在较低温度下进行氨解或使用体积较大的胺可以防止机械强度的大幅下降。此外,我们还研究了以葡萄糖内酯和乙二胺为原料合成的糖胺(GlcNH2)对涤纶织物的氨解作用。
In the preceding paper, it was found that a combination of the aminolysis of PET fabric by ethylenediamine and the following reaction with sugar-lactone gave a large increase of the hydrophilicity of PET fabric, but the former reaction caused decrease in its mechanical strength readily. Here, the effects of a reaction temperature of aminolysis and the structure of amines on the mechanical strength and an amount of water vapor adsorbed on it were examined. As a result, aminolysis at lower temperature or by using higher bulky amines prevented large decreases in the mechanical strength. Furthermore, we reported on the aminoiysis of PET fabric by sugar-amine (GlcNH2) synthesized from gluconolactone and ethylenediamine.
