All the modern rugs you see on line are hand tufted rugs, however the definition of tufting is a Pile consisting of tufts or loops formed by inserting a yarn into a previously prepared backing fabric.
The yarn forming the pile stands verticle to the base or ground. The pile is cut and the backing fabric is woven. Parallel rows of stitches can be seen on the back of tufted fabric. So a thin coating of of adhesive is applied to the back to hold the pile yarns in place. Once the rug is sheered and the adhesive is dried it's ready to be sent to the customer.
