摘 要：本文采用先合成高分子量的有機硅陰離子乳液，再加入氨基單體進行改性，并根據熱力學平衡原理，制備出高分子量、氨基改性的有機硅陰離子乳液。研究結果表明：在固含量15%、單體預乳化再滴加、TX-10為非離子乳化劑的條件下，獲得的硅油分子量比市場上同類產品高，并經織物手感測定，滑爽性能優異。在此基礎上，將上述合成的乳液與交聯劑，催化劑復配成平滑整理劑，用于整理三維中空滌綸短纖維的平滑性。并討論了氨基含量、催化劑用量、交聯劑用量對織物平滑性、柔軟性及牢度的影響。最后可得，在氨基含量6%、催化劑含量1%、交聯劑含量為0.25%時，獲得的乳液效果與國外同類產品相媲美。

Abstract: This article described a high molecular weight, amino-modified silicone emulsion was prepared that synthesis of the high molecular weight anionic silicone emulsion in advance, and then join the amino-modified monomer according to thermodynamic equilibrium theory. The results show that: the molecular weight of the silicone which received in the conditions of solid content of 15%, dropping the pre-emulsification monomer, TX-10 as for non-ionic surfactant, than similar products on the market, and the feel of fabric, smooth performance excellence. On this basis, the emulsion and cross-linking agent, catalyst matched to the smoothing agent which used to finish three-dimensional hollow polyester staple of the smooth. Effects of amount of the amino content, catalyst and crosslinking agent to fabric smooth, soft and fastness were studied. Finally, the amino content in six percent, catalyst in one percent, crosslinking agent content in 0.25 percent, can access to the emulsion and the effect comparable to similar foreign products.
