    • The present invention discloses a modifier for modifying a polyester fiber as well as a preparation method and application of the same. The modifier contains ethylene glycol, two-hydroxy-end polyether, dimethyl terephthalate, two-polyether-end modified organosilicon and a metal acetate catalyst. A two-step continuous production process is adopted. The first step is esterification; that is, ethylene glycol, two-hydroxy-end polyether, dimethyl terephthalate, and two-polyether-end organosilicon are added into a reactor, and have an esterification reaction in the presence of the catalyst. In the second step, the materials produced by the esterification are transported to a polymerizer, and have a polymerization reaction under the conditions of high temperature, vacuum and catalyst, producing the high molecular weight polyester/polyether/organosilicon terpolymer with a molecular weight of 1000˜50000 as the desired modifier. This modifier can be used either directly or in combination with some other substances such as surfactants, so as to modify the polyester fiber.
    • 本发明公开了一种改性聚酯纤维的改性剂及其制备方法和应用。 改性剂含有乙二醇,二羟基端聚醚,对苯二甲酸二甲酯,双聚醚端改性有机硅和金属乙酸酯催化剂。 采用两步连续生产工艺。 第一步是酯化; 即将乙二醇,二羟基端聚醚,对苯二甲酸二甲酯和双聚醚末端有机硅加入到反应器中,并在催化剂存在下进行酯化反应。 在第二步中,将通过酯化生成的原料输送到聚合反应器中,在高温,真空,催化剂的条件下进行聚合反应,生成高分子量聚酯/聚醚/有机硅三元共聚物,分子量为1000 〜50000作为所需的改性剂。 该改性剂可以直接使用或与一些其它物质如表面活性剂组合使用,以便改性聚酯纤维。
