Hand-knotted
pile carpets are the most durable in
tenure. Tufted carpets with different
types of piles or loops are also
available but knotted are the best in
the category. Usually an Oriental rug
quality is judged by the knots per
square inch. The more the count, better
the quality.
Types
The most common types of knots used in
an oriental carpet are:
Persian knot: It is an
asymmetrical single knot also called
Senneh knot or Farsibaff. Here the
thread forms only one loop around one of
the two warps. So the pile threads vary
in protruding between the adjacent
warps.
Turkish knot: It is a symmetrical
double knot type also called Ghirdes.
Here the pile thread forms a loop around
two warps. Both ends of the pile thread
come out between both warps.
Jufti knot: It can be symmetrical
or asymmetrical and the difference is
that it is formed over four wraps.
Tibetan knot: A temporary rod
which establishes the length of pile is
put in front of the warp. A continuous
yarn is looped around two warps and then
once around the rod. Once through with
the row, the loops are cut to form the
knot.
Moreover, each knot gives a different
texture to the carpet.
Knot Density
Knot density is an indicator of quality.
More the number of knots per square
inch, better the quality. KPSI is the
density i.e. knots per square inch.
• 80 or less KPSI denotes poor quality
• 120 to 330 is medium to good
• 330 or more KPSI denotes good to very
good quality and more than that are
classified as exclusively fine pieces.
