Cotton is a primary material for almost every hand-knotted rug. The warp and the weft—the vertical and horizontal skeleton of a rug—is often made from cotton, allowing it to hold its shape.
A standard wool rug is roughly 20% cotton and 80% wool. Although most rugs contain some degree of cotton, when Green Front refers to cotton rugs, we are describing rugs primarily made from cotton, including dhurries, rag rugs or printed rugs.
Cotton pile rugs are not very common since wool is naturally more hydrophobic (repels water) and easier to clean. However, cotton rugs feature a unique texture and finish, which can make it desirable for certain applications.
