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.
