ʷ The polymethylhydrosiloxane(PMHS) was synthesized by the co-hydrolysis of methyldichlorophydrosilane and ethyl ether, also polydimethylsiloxane(PDMS) was synthesized by the hydrolysis of dimethyl dichlorosilane and ethyl ether. The silk fabrics were treated with PMHS and PDMS in order to improve the water repellency and the wrinkle recovery. Also the effect of PMHS concentration, PDMS concentration and cure temperature on the physical properties of silk fabrics were studied. The maximum water repellency and maximum wrinkle recovery were obtained from the fabrics treated under the conditions 5%-PMHS and PDMS at 16, and 3%-PMHD and PDMS at 16, respectively. The tensile strength, the breaking elongation, the reflection and the bending properties of silk fabrics were not degraded severely by the treatment of PMHS or PDMS.
