Rope is used for only one thing in the Lost in Blue series; building! You can use rope to build anything from rafts to tables to even tree houses. Rope can be braided from Tree vine by a female character, such as Claire.
Rope is made from tree vines. Put the tree vines in the rope pile. Go up to Skye and request her to make rope. The finished rope can be found in the pile you left the vines. You cannot see the rope in your inventory. The only way to find out how much you are carrying is to view the rope pile.
