What are the white spots on my rug?
As my rug has gotten older I have noticed white spots on it. I have not used any chemicals on my rug so I don’t know why there are tiny white spots on it.
Here at Behnam Rugs Persian Rug Cleaner we hear rug owners ask about white spots on their rugs. We make sure before we pick up their rug for washing we evaluate each rug and inform the customer there might be more white spots after a good professional washing.
Mr. Ben “Behnam” Tavakolian of Behnam Rugs says:
There are two kinds of white spots that show up on your hand made rugs.
- Knot Heads
- What is a knot head? Do all rugs have knot heads?
- Where are knot heads found on a rug?
Knot heads happen naturally during the weaving process of a rug. The weaver pulls on the worp to make a knot with the wool to create the pile of the rug tension is needed to make the worp thread and sometimes the fiber will break. The wool or cotton thread will then need to be extended this is where the new piece created the knot head. Each broken warp will be secured with two knot heads. The size of the knot head will depend on the size of worp and cotton yarn and density of the rug.
Where are the knot heads found?
Knot heads are found in all handmade rugs. Generally the weaver will hide the knot heads between the pile of the rug by using a combing hammer to comb down the pile of the rug to keep knot heads from being exposed on the surface.
Seeing knot heads is natural as the rug gets older and the pile gets shorter the knot heads will begin to come to the surface. Proper rug padding will keep this from happening prematurely. Sharp micro dust, sand and dirt in an unwashed rug will lose more pile due to friction grime against the rug pile. Other factors that make knot heads show on the surface faster depends on the type of rug, country or origin and traffic pattern but all will age your rug faster if not maintained.
Knot heads could be carefully removed by re-weaving areas or in most cases just by coloring them to match the surrounding knot heads.
- White spots can be from threadbear also.
