That's a new one...

Immaculate Silk
Quest, Temporary
This item can be used in tradeskills.

Dropped in Steam Factory... I've done a TON of soloing in steam factory and I've never seen that drop before.

I haven't seen it myself, but the description of the item over on Allakhazam doesn't mention it being Temporary (or Quest), so that's odd. The post there also says the item is req level 85, recommended 89, and has Item Lore: Exquisite Silk. Alla also lists Immaculate Animal Pelt.

All of that suggests that this is for the next tier of cultural silk armor (though I thought Ngreth said there wasn't going to be any new armor past Exquisite?), and quite possibly it wasn't supposed to go live or something. (Note that the Lore looks like it was copied verbatim from the level 80-84 silk.)

I acquired 3 of them over the course of a week or so. But then I was forced to log out and lost them. I havent been back to steam factory since then (and probably wont be going ever again thanks living legacy for dropping the buyer prices on porous loams et al into the toilet )

I got a similar type drop a few days ago.

I cant remember what or where, but it was a temp/tradeskill/quest item (i think there were 3 of them stacked in one loot).

Sorry I cant remember much about it, but I know for sure it wasn't in the Steam Factory as I dont hunt there.

I've seen a couple of the Required 85 items so far, I'm guessing they're supposed to be for the new expansion when the cap is raised to 85, most likely for the new level cultural.
