slow speeds/ clutch noise
 

I have a 1999 pathfinder SE. I went on a road trip this weekend and put on about 1000Km. Everything was fine until I started driving yesterday morning, the day after I got back. When I'm driving at slower speeds(0-20Km/h) and I put the clutch in, there is a rubbing noise. This only happens when the engine is cold with the clutch in but as soon as the engine heats up, the noise goes away, even with the clutch in at slower speeds. Any suggestions as to what could be causing this? Thanks.
