In technical terms the foundation of the rug is comprised of warps and
the wefts, the vertical and horizontal yarns upon or into which the pile or
facing is woven. On the loom, the warps run vertically, while the wefts run
horizontally, alternating over and under each successive warp. Essentially
the foundation is the substructure that supports the pile or flatwoven
facing and holds the rug together. The foundation, i.e. the warps and wefts,
can be made entirely of wool, cotton, or silk, or some combination of these.
Some rugs have wool warps and cotton wefts; others have the reverse. Warps
are generally made up of plied yarns of either wool, cotton, or silk.
Wefting can be unplied or plied, and in the latter case it can combine these
different materials. |
