摘要:
The present invention discloses a modifier for modifying the polyester fiber as well as preparation method and application of the same. The modifier contains ethylene glycol, two-hydroxy-end polyether, dimethyl terephthalate, two-polyether-end modified organosilicon, and 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 is 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.
