High purity methylphenyl dimethoxysilane was synthesized using methyltrimethoxysilane as the raw material. Using this monomer and diphenyldimethoxysilane as raw materials, after complete co hydrolysis, various phenyl molar contents of methylphenyl silicone oil and diphenyl silicone oil were obtained through equilibrium condensation using hexamethyldisiloxane as a blocking agent and trifluoromethanesulfonic acid as a catalyst.

Vinyl terminated phenyl silicone oil was prepared using diphenyldimethoxysilane and dimethyldimethoxysilane as raw materials, and 1,3-divinyltetramethyldisiloxane as a blocking agent. Phenyl hydrogen containing silicone oil was synthesized using diphenyldimethoxysilane, dimethyldimethoxysilane, and methyldichlorosilane as raw materials, and hexamethyldisiloxane as a blocking agent.

Finally, several phenyl silicone oils were applied to fabric treatment, and the mechanical properties, whiteness, and fastness of the fabric before and after treatment were compared and tested. Research has found that the tensile strength of fabrics treated with phenyl silicone oil is generally enhanced, but the whiteness slightly decreases. When using phenyl silicone oil to treat colored fabrics, the soaping fastness, wet friction fastness, and sun fastness of the treated fabrics are all improved by one level.
