What Is Cashmere Wool Made From?
The complete beginner's guide — what cashmere actually is, where it comes from, why it is not technically wool, and what makes it one of the finest natural fibres on earth.
If you are new to cashmere — if you have seen the word on a label, wondered what it means, and wanted a clear, honest answer — this is the article for you. No assumed knowledge. No jargon without explanation. Just a precise, complete answer to the question: what is cashmere, where does it come from, and why does it matter?
By the end of this article you will know what cashmere actually is, why it is called "wool" when it technically is not, which animals and which parts of the world produce it, how it becomes the fabric you wear, and where to go next if you want to understand any part of the story in more depth.
1. First — Cashmere Is Not Technically Wool
The phrase "cashmere wool" is so widely used that most people accept it without question. But it contains a small inaccuracy worth correcting at the outset — because understanding the correction helps you understand what cashmere actually is.
Wool, strictly speaking, comes from sheep. It is the fleece of the domestic sheep — sheared once or twice a year, processed into yarn, and woven or knitted into fabric. Wool is abundant, widely produced on every continent, and ranges from coarse and scratchy to superfine and soft, depending on the breed of sheep.
Cashmere comes from goats — specifically from the fine undercoat of goats belonging to the species Capra hircus. It is not sheared. It is combed, or gathered during the natural spring moulting season when the goat sheds its winter undercoat. The fibre is finer, rarer, and more thermally efficient than sheep wool. It is a different material from a different animal by a different process.
So why is it called cashmere wool? Historically, "wool" was used as a general term for any soft animal fibre — a usage that has persisted in common language even as the textile industry developed more precise vocabulary. Today, "cashmere wool" is a colloquial description, not a technical one. The correct term is simply cashmere — or, for the finest grade of cashmere, Pashmina.
📋 The Quick Distinction
Wool: From sheep. Sheared. Abundant. Wide range of quality from coarse to fine.
Cashmere: From goats. Combed during natural moulting. Relatively rare. Consistently fine and soft.
Pashmina: The finest grade of cashmere — from the Changthangi goat specifically, in Ladakh, India. 12–14 microns in diameter. The subject of this knowledge base.
2. The Animal — Which Goat, and Why It Matters
Not all goats produce cashmere. The fibre comes specifically from goats of the species Capra hircus that have developed a fine, dense undercoat as an adaptation to cold climates. Several breeds across multiple countries produce this undercoat — but they are not all equal in the quality of fibre they produce.
The cashmere goat has two distinct layers of fibre:
The process of separating these two layers is called dehairing — one of the critical early stages of cashmere production. After dehairing, what remains is pure cashmere down — the raw material that will eventually become the scarf or shawl you wear.
🔬 Why the Inner Coat Is So Fine
The fineness of the cashmere undercoat is a direct biological response to cold. In extreme climates — particularly at high altitude — the goat's body produces the densest, finest undercoat it can to maximise thermal insulation efficiency. The colder and higher the environment, the finer the fibre. This is why Changthangi goats on the Ladakh plateau at 4,000 to 5,000 metres produce the finest cashmere on earth — their environment demands it.
3. Where Cashmere Comes From — The Producing Regions
Cashmere is produced across a broad geographic band that stretches from the high plateaus of Central Asia through China and down to the mountains of northern India. The quality of the fibre varies significantly by region — determined primarily by altitude, temperature, and the specific breed of goat.
| Region | Altitude | Typical Diameter | Annual Yield / Goat | Global Position |
|---|---|---|---|---|
| Changthang, Ladakh (Pashmina) | 4,000–5,000m | 12–14 microns | 80–100g usable | Finest grade — Pashmina |
| Mongolia (Gobi) | 1,000–1,500m | 15–17 microns | ~250g usable | 2nd largest producer |
| Inner Mongolia / China | Low–medium altitude | 15–18 microns | ~300g usable | Largest producer by volume |
| Iran | Variable | 16–19 microns | ~250g usable | Traditional producer |
| Afghanistan | Variable | 16–18 microns | ~250g usable | Regional producer |
The pattern is consistent across all regions: higher altitude, colder winters, finer fibre, lower yield per animal. The Changthang plateau sits at the extreme end of all four variables — which is why the fibre it produces is categorically different from commercial cashmere, not just marginally better.
4. How Cashmere Becomes the Fabric You Wear
Understanding the journey from goat to finished scarf helps explain both why cashmere is priced the way it is and why the process cannot be significantly accelerated or mechanised at the finest quality levels. Here is the complete sequence in plain terms.
Combing — Spring, Changthang Plateau
Each spring as temperatures rise, the Changthangi goat naturally sheds its winter undercoat. Herders comb the goat by hand using a wide-toothed comb to gather the loose pashm before it is lost to the wind. One goat yields approximately 240 grams of raw fibre per year — a palm-sized handful. This is the entire annual harvest from one animal.
Dehairing — Separating Coarse from Fine
The raw combed fibre contains both the fine pashm undercoat and coarse guard hairs. These must be separated — a process called dehairing — because any remaining guard hair in the finished fabric causes itching and reduces softness. After dehairing, approximately 80 to 100 grams of usable pashm remains from the original 240 grams. The rest is discarded or used for lower-grade products.
Hand-Spinning — Kashmir Valley Villages
The cleaned pashm is hand-spun into yarn on a traditional Kashmiri spinning wheel called a yindeer. At 12 to 14 microns, the fibre is too fine for industrial spinning machinery — it breaks under mechanical tension. A skilled spinner — traditionally a woman, working from home — produces 100 grams of yarn in approximately 24 hours of continuous work. The spinning is not a craft choice. It is a physical necessity dictated by the fineness of the fibre.
Starch Treatment and Warping
Before weaving, the spun yarn is treated with a light rice starch coating — called maya in Kashmiri — to give it temporary strength for the mechanical action of the loom. It is then wound onto small wooden spools called prech and set up on the loom in a process called yarun (warping). A standard scarf requires 1,200 or more individual warp threads, each set by hand at consistent tension.
Hand-Weaving — Khaddi Loom, Kashmir
The yarn is woven by hand on a traditional pit loom called a khaddi. The weaver sits at ground level, operating foot pedals and passing the weft thread across the warp by hand, beat by beat. A plain cashmere scarf involves more than 100,000 individual weft passes. The Cheshme Bulbul diamond weave pattern used by Pashwrap requires additional precision at every pass to maintain the repeating diamond structure across the full width of the fabric.
Washing and Finishing
The woven fabric is washed in cold, clean water using natural agents to remove the starch treatment and relax the fibre. This washing and finishing stage — approximately six hours — is what transforms the stiff woven cloth into the cloud-soft fabric cashmere is known for. The starch scaffolding comes out. What remains is the pure fibre, relaxed and open, with its natural softness fully expressed for the first time.
5. Cashmere vs Wool — The Key Differences
Now that you understand what cashmere is, it helps to see how it compares to sheep wool — the fibre it is most commonly confused with, and the fibre most commonly used to adulterate or imitate it in blended products.
| Property | Cashmere (Pashmina-grade) | Merino Wool (finest grade) | Standard Sheep Wool |
|---|---|---|---|
| Source animal | Capra hircus goat | Merino sheep | Domestic sheep |
| Fibre diameter | 12–14 microns | 17–19 microns | 20–40+ microns |
| Harvest method | Combed during moulting | Sheared | Sheared |
| Annual yield per animal | 80–100g usable | 2–5kg | 2–10kg |
| Softness against skin | Exceptional — no prickle | Very good at finest grades | Variable — often prickly |
| Warmth-to-weight ratio | Highest — finest air-trapping | Good | Good but heavier |
| Machine washable? | No — hand wash only | Some grades yes | Some grades yes |
| Price | High — rarity and process | Moderate | Low to moderate |
| Lifespan with care | Decades — improves with age | Several years | Several years |
The most practically important distinction for a buyer is the fibre diameter. At 12 to 14 microns, genuine Pashmina-grade cashmere sits well below the 19-micron threshold at which human skin begins to perceive prickle or roughness. Fine merino at 17 to 18 microns also sits below this threshold — which is why it passes many of the same softness tests as cashmere and is the most common sophisticated substitute. Standard sheep wool is above the threshold and is perceptibly scratchy against sensitive skin.
📏 The Micron — The Number That Matters Most
A micron is one millionth of a metre. A strand of human hair is approximately 70 microns in diameter. Pashmina-grade cashmere at 12–14 microns is five times finer than a human hair. Standard commercial cashmere at 19 microns is around four times finer. This is why the difference between 14-micron Pashmina and 19-micron commercial cashmere is not marginal — the 5-micron difference produces a fabric that is physically, measurably, and perceptibly different in softness, drape, and warmth.
When you are buying cashmere, the micron count is the single most important specification to know. Always ask for it.
6. What Makes Genuine Cashmere Worth Understanding
If you have read this far, you now know more about cashmere than the majority of people who buy it. That knowledge matters because the cashmere market is one of the most widely mislabelled textile categories in the world. Synthetic products, cheap wool blends, and machine-processed commercial fibre are routinely sold under the cashmere label — at prices that make genuine cashmere seem overpriced by comparison.
They are not comparable products. Genuine Pashmina-grade cashmere — combed from a Changthangi goat at 4,500 metres, hand-spun by a woman in a Kashmir village, hand-woven by an artisan who learned the craft from his father — is a specific, rare, irreplaceable object. The label "cashmere" covers an enormous range of quality. The knowledge to navigate that range is what protects you as a buyer.
Cashmere is not a category of product.
It is a specific fibre from a specific animal in a specific place.
Everything else is an approximation.
