Terry cloth is woven on a loom using two individual sets of warp threads. One set of threads has a very loose tension. When the filling yarns are woven and then packed, the looser set of threads is pushed backward, forming the characteristic loops of thread. With regular terry cloth, there are loops on both sides of the fabric. French terry cloth, on the other hand, is woven so that the loops of thread are only on one side of the fabric. The other side is smooth, flat and knit-like in texture
