2、、涤纶织物的浸渍时间及聚醚酯浓度对抗静电性能的影响，用红外光 谱、DSC 对其表征；合适的合成工艺：酯交换温度 180-190；缩聚温度为 210-230左右， 催化剂为三氧化二锑，真空度 756mmHg 左右。实验结果表明，聚醚酯的抗静电性能随着 PEG 分子量的升高而下降，用分子量为 2000 的 PEG，含量为 70%，合成的聚醚酯是一种综合性能 较好的抗静电剂。结构中引入 SIPM 能有效提高抗静电性。合适的后处理工艺条件：聚醚酯 浓度为 0.2%，浸渍时间为 10min，烘焙温度为 160。 关键词：表面处理；抗静电性；聚醚酯；红外光谱 Preparation and perform
