摘要：有機硅由于其結構的獨特性，所制成的平滑劑可賦予紡織物舒適，滑爽的手感。本實驗以羥基封端的低分子量硅油（線性體）為主要原料，LiOH為催化劑，并選擇帶有不同官能團的偶聯劑，在真空脫水狀態下制備特種硅油。再經乳化獲得滌綸長絲平滑劑。在此基礎上，詳細討論了氨基改性硅油的制備、乳化及手感評價，并進行配方優化，結果表明：氨基含量15%、分子量5萬左右的硅油，采用TX-3：TX-10=1：2的復合乳化劑乳化制得的氨基改性滌綸長絲平滑劑具有優異的性能。此外，我們還制備了環氧基、巰丙基、哌嗪基、脲基等改性的滌綸長絲平滑劑，通過性能評價發現，這些基團改性均不如氨基改性的滌綸長絲平滑劑的性能優異。

Abstract: Smoothing agent made of by Silicone ,which had a unique structure, can give textile fabrics comfort and smoothness handle. In this experiment, it used low molecular weight hydroxy-terminated silicone oil (linear) as the main raw material, LiOH as catalyst and selected coupling agent that with different functional groups, and prepared special silicone oil in a vacuum dehydration state. Then, Polyester Filament smoothing agent was gained by emulsion. On this  basis, it discussed the amino-modified silicone oil preparation, emulsifying , handle eva luation and formulation optimization in detailed. The results showed : the amino-modified polyester filament smoothing agent which was produced by amino-Content15%, molecular weight of about 50,000 silicone and composite emulsifying that used TX-3 : TX-10 = 1 : 2 had a excellent performance. Besides, we also prepared epoxy, mercapto-propyl, piperazine, urea-modified polyester filament smoothing agent, it found that the performance of amino-modified polyester filament smoothing is better than all of these.
