Something like this really requires a fairly high level of 3d modeling skill and ability to make animations if you want this NPC to look like an NPC and not some corpse. The reason being that NPCs typically have to always be standing on something (even if its a collision box) and would not look right when bound with a rope unless some rather complicated arrangement was setup.
If you have a skilled animator on the payroll, you could probably achieve the desired effect by creating a roped clothing mesh which is weighted to the skeleton with the arm and hand portions weighted to the body (so they are stuck to the sides of the NPC). Then combine that with an idle animation, based off the sitting animation in terms of node setup, where their legs are beneath them dangling. Then setup an invisible chair, with a rope leading to it from the ceiling above that the NPC will be sitting on that is linked to the animation. Combine it with scripting and packaging to force the actor to the position, as well as scripting to break the bonds and swap out the clothing, and you'll have something to work with.
If you don't, you might want to consider a less problematic situation of a sitting hostage. While it might not have the effect you're looking for, it doesn't require special components to be made.
