폴리메틸 히드로 실록산과 폴리디메틸 실록산으로 처리한 견섬유의 물성에 관한 연구

A Study on the Physical Properties of Silk Fabrics Treated with Polymethylhydrosiloxane and Polydimethylsiloxane

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$0^{\circ}C$, and 3%-PMHD and PDMS at 16$0^{\circ}C$, 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.
