How can i dye an american sapphire blue jacket a navy sapphire what sort of dye would i use?

it is an american jacket it is like a polyester silk

you can probably use rite dye and dye it in the washer but after you dye it be sure to soak it in a solution of plain white vinagar and water for about an hour use a 30% vinagar and 70% water ratio this will set the dye into the fabric and you will have less color bleed when you wash it but don't wash it for 48 hours after dying it giving the dye time to fully dry
