Silk vs. wool
Once a hand-knotted oriental rug is on the shortlist, the material question comes up sooner or later. Silk or wool? Both are natural fibres with a long tradition and very different characters. This page compares them directly, with clear recommendations per living situation.
Seven criteria compared directly
The short form for those in a hurry. The sections below go deeper into each of these criteria.
| Criterion | Silk | Wool |
|---|---|---|
| Sheen | naturally shimmering, refraction shifts with viewing angle | matte glow, calm character |
| Knot density | 400,000–1,500,000 knots per m² | 120,000–500,000 knots per m² |
| Durability | soft, prone to pressure marks, unsuitable for traffic zones | robust, springy fibre, copes with high-traffic rooms |
| Care | dry cleaning, no water, no household remedies | vacuuming, spot cleaning, professional wash every 5–10 years |
| Lifespan | 30–80 years with correct storage | 60–150 years, often outlasting generations |
| Price per m² | 1,500–8,000 euros depending on knot density | 200–4,000 euros depending on quality |
| Best rooms | bedroom, wall hanging, display piece | living room, dining room, hallway, bedroom |
#Sheen and play of light
The first difference everyone sees: silk shimmers. A silk fibre is wafer-thin and smooth, and reflects light in a narrow, directed angle. From two metres away, a silk rug looks like two different pieces, depending on whether you face it from north or south.
Wool is a crimped fibre with an irregular surface. It scatters light rather than mirroring it. A wool rug keeps its character from any angle and under any light source. That feels calmer and more inviting, but less spectacular.
For representative rooms with daylight from two sides, silk can be a sensible choice. For rooms used mainly in the evening with a cosier mood, wool remains the first choice.
#Durability and traffic patterns
This is where the practical gap opens up. Silk is soft and smooth, which makes it lovely to touch, but sensitive to pressure and friction. A sofa leg leaves a visible imprint after weeks. A spot walked on every day glows noticeably differently from the rest after a year.
Wool is crimped and bounces back. Press a wool rug with your finger, and the spot returns to shape within seconds. That is also why wool rugs still look acceptable in the traffic line even after 50 years, while silk rugs visibly wear at heavily used spots.
Rule of thumb: silk belongs where people walk rarely or quietly. Bedrooms, formal dining rooms, showroom pieces. Wool belongs in any room used daily.
#Care and risks
Wool is surprisingly easy to care for. The fibre absorbs up to 30 percent of its own weight in moisture without feeling wet, and releases it again. That makes wool largely insensitive to spills, provided you blot quickly. A professional wash every 5 to 10 years is enough for living-room pieces.
Silk does not tolerate water. A spilled glass of red wine that a wool rug shrugs off often leaves permanent damage on silk. Even household remedies like vinegar water or sparkling water are off the table. Silk rugs need dry cleaning by a specialist and must be protected from sunlight, because the fibre fades quickly under UV exposure.
For families with children and pets, the answer is clear. Wool. For collectors who want to design a special room, silk can be the right choice if the care requirements are accepted.
#Knot density and fine patterns
Knot density is closely tied to material. Silk allows finer knots than wool, because the fibre is thinner and more uniform. Hereke silk rugs from today's Turkey reach 1.2 to 1.5 million knots per square metre, with some special pieces up to 2 million.
Wool rugs sit mostly between 200,000 and 500,000 knots per square metre. Top works from Nain or Isfahan reach 800,000, the upper limit of what is possible with wool.
For figurative or highly detailed patterns, this density is a technical advantage of silk. On a Hereke silk rug you can see horses with individual mane hairs, something simply impossible in wool. For classic geometric or floral designs, wool density is fully sufficient.
#Price and value development
Silk is significantly more expensive than wool, both at first purchase and across the lifespan. A Hereke silk costs 2,500 to 8,000 euros per square metre, a comparably sized Bidjar or Heriz in wool 600 to 2,000 euros.
In value retention, the gap shows itself differently. Antique wool rugs of collector quality hold or gain value, because the substance still carries after 80 years. Antique silk rugs are rarely in good condition, because the fibre wears down over decades. The most expensive auction pieces are almost always old wool rugs with a story, not old silk.
For the average buyer this means: wool is the economically better choice. Silk is an aesthetic decision made deliberately.
