My first thought is why would you want to de-interlace your text? What is your end product? VIdeo Print? web? I never de-interlace for any reason though. I think the only reason you'd want to to use this (or what its meant for) is if you are using stills from DV video.
I don't quite understand what you mean when you say "...so I believe when finalized this TEXT image of NAMES I "
That being said, at least in the version of photoshop that I have, you cannot apply a filter to a text layer. You need to rasterize it first. So duplicate you original text so you don't lose edit-ability.
If you want to make the same effect every time on various titles, I would learn about how to make an action.
