If you don't deactivate your particles from the bind solver, they'll never return to their original location because even after you interpolate them, the solver will change their position in accordance with the cloth/bind settings.
So the first thing you need to do is deactivate particles with a Particle Switch, once you want them to return.
Also, the default interpolation method is linear interpolation (lerp), which will move your particles based on the specified interpolation value (it's a value of 0-1, so 0.1 would be a 10% lerp towards the target). Linear interpolation has a ramp-in effect, where the visual interpolation amount will slow over time and ease-in to the target. Newer tyFlow builds have other curve-based interpolation methods you can use instead, to fine-tune how the ramping/easing occurs.
