摘要：有机硅由于其结构的独特性，所制成的平滑剂可赋予纺织物舒适，滑爽的手感。本实验以羟基封端的低分子量硅油（线性体）为主要原料，LiOH为催化剂，并选择带有不同官能团的偶联剂，在真空脱水状态下制备特种硅油。再经乳化获得涤纶长丝平滑剂。在此基础上，详细讨论了氨基改性硅油的制备、乳化及手感评价，并进行配方优化，结果表明：氨基含量15%、分子量5万左右的硅油，采用TX-3：TX-10=1：2的复合乳化剂乳化制得的氨基改性涤纶长丝平滑剂具有优异的性能。此外，我们还制备了环氧基、巯丙基、哌嗪基、脲基等改性的涤纶长丝平滑剂，通过性能评价发现，这些基团改性均不如氨基改性的涤纶长丝平滑剂的性能优异。

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.
