Abstract: Coated with silicone rubber can not only give fabrics various properties, and by using functional silicone materials to the special reaction, Fabric can also be given oily, paper outstanding special feeling, which is of broad application prospects in some field such as underwear fabric, thus it is worth studying. In this study, two polymerization technology were designed trough the molecular control engineering, and technological improvement and the optimal formulation. The results show: for the technology 1, ultra-high molecular weight silicone oil is prepared under the condition as follows: the polymerization temperature is 90 ° C, the amount of catalyst is 0.0001%,hydrolysates amount of 0.08% (relative monomer content). By adding the amount of 10% feeling formation agent, the target products and the optimal apply portfolio period is availed; Considering the technology 2, The three components coated with silicone rubber that meet the requirements can be prepared under the condition as follows: the polymerization temperature is 50 ° C, the amount of catalyst is 0.01%. Graft polymer main chain was 1% (25% relative toluene solution in terms of silicone oil) and the initial oil viscosity is 1000000 mPa.s .Comparatively speaking, the process of technology 1 is more difficult, and the technology 2 relatively needs more curing time, all have their pros and cons.
