How do I get black sharpie off my оранжевый backpack * read Описание for еще details*

Okay a couple of months назад my stupid ex boyfriend wrote his name on my back pack in black sharpie and now I don't want it on there and it won't come off. Iv tried nail polish remover and it didn't work. It's an оранжевый L.L. фасоль, бин back pack and it's kinda a flannel cargo fabric. Any help would be SOOO appreciated THANK YOU!
