Umm no it won't ever disappear unless you salvage it or sell it or delete your character. If you do not do those 3 things then your armor is there forever.
Nothing ever disappears in GW. As for the faction, all it determines is that you are only able to speak to NPCs of that faction if you have, at that moment, more unspent faction of their faction than the other faction.
Apart from that, items will stay, and while when you spend faction you lose opposing faction, that just means you can't spend that faction - the titles will keep on counting, as they count the faction SPENT, not unused.
