摘要
以聚对苯二甲酸乙二酯(PET)为主体添加聚乙二醇(PEG)的共聚物以及以聚对苯二甲酸乙二酯为主体添加含有磺酸盐基团的共聚组分和聚乙二醇的共聚物是两类重要的成纤共聚醚酯,前者(简称为PEE-1)制成的纤维可用分散染料常压沸染,后者(简称为PEE-2)制成的纤维则可用阳离子染料进行染色。
The effect of molecular weight of polyethylene glycol(PEG) on two kinds of copolysters was investgated. One is polyethylene terephthalate polyethylene glycol(PET-PEG) block copolyester, the other is - SO3Na group contained PET-PEG copolyester. It was shown that the higher the molecular weight of PEG the quicker the crystallization rate of copolyester. The result of difference in dyeability between copolyesters with PEG of different molecular weight was also obtained.
