carpet consists of two parts: one is
"foundation", which is formed by warp and weft
yarns and the other is the "pile"
yarns are the vertical strands of
fibers stretching from the top to the bottom of
a carpet. They are extremely important
components because the knots are tied to them
and the weft yarns are woven through them.
Generally, if the warp yarns are not evenly and
tightly woven, a carpet is easily to get
yarns are the horizontal strands that
stretch from the left to the right side of the
They are woven through the back and
front warp yarns and added before or after the
rows of knots, to prevent them from becoming
loose. Usually the warn and weft yarns use the
same fiber i.e. cotton, wool or Silk in
hand-made carpets. Cotton is most widely used
due to its lowest cost but wool is still quite
popular in places where it is readily available.
Silk is the most expensive one but it's quite
strong and elegant and thus is highly
recommended as the foundation for high quality
"pile" forms the designs and patterns
and in effect is the 'working surface' of the
completed carpet. It is the upright end of
strand which is shaped by the knots that may be
cut or looped.
Knots used in
weaving skill is the most widely used method of
making a carpet. There are different ways of
knot weaving but basically Persian knot and
Turkish knot are one of the most popular ones.
Persian knot is symmetric whereas , Turkish knot
One piece of strand is wrapped
around another warp yarn and then passed under
its adjoining warp yarn. The two ends are
brought to surface separately, creating
better-look designs. Persian knots matches
asymmetrically beside the other strings of a
basis; the first nap yarn twists one string of a
basis entirely whereas the second - only half
To form a symmetric knot, one
piece of strand is wrapped over two adjoining
warp yarns and both ends of the strand are then
pulled back together to surface between the two
warp yarns. Both strings of a basis are
completely twisted with a nap yarn.
