RugStore: Knots used in weaving the rugs
Knots are the building blocks of the rug. There are four types of knot are in vogue - Asymmetrical (Persian or Senneh) Knot, Symmetrical (Turkish or Ghiorde) Knot, Jufti Knot, Tibetan Knot. In these asymmetrical and symmetrical Knots are generally used knots to weave the rug.
Asymmetrical Knot
The knot is tied by warping yarn around the warp strings and pass under the next warp string and bringing back on the surface, by this a fine weave is achieved. This type of knot is generally practiced in Iran, India, Turkey, Egypt and China.
Symmetrical Knot
The knot is tied by passing yarn over two adjacent warp string simultaneously, after that end of each yarn is enfold behind one warp and bring back to the surface between the two warps. This type of knot is generally practiced in Turkey, Caucasus and Iran by Turkish and Kurdish tribes and in some European rugs.
Jufti knots
Jufti knot type can either be symmetrical or asymmetrical style. Jufti knots are tied over four warps in place of two to make the weave faster and it consume half of the material when compare to symmetrical or asymmetrical knot rug. Durability of the rug is less. Use of this knot can be seen in the rugs of khorasan and Bokharas, sometime you can find the mix of Jufti and Persian knot.
Tibetan Knot
In Tibetan knots different technique is used, in front of the warp a temporary rod is inserted along the length of the pile and the yarn is enfold around the two warps to form loop and once around the rod, later the loops are cut to knot.
