Not made smooth; having a rough or uneven surface.
The unsmoothed surface of the table made it difficult to write on.
Unsmoothed → It is formed from "un-" (meaning not) and "smoothed" (from Old English "smythian", meaning to make smooth). The word "unsmoothed" means not made smooth or rough in texture.
Think of 'not' ('un-') making something 'smooth' — that's why unsmoothed means it hasn't been made smooth.
