Wool is a natural fiber that is produced by sheep and other animals, including goats, alpacas, and llamas. It is known for its ability to keep people warm in cold weather and is a popular choice for clothing, blankets, and other textiles. But how does wool work to keep us warm, and why is it so much warmer than cotton, a commonly used natural fiber? In this article, we’ll explore the properties of wool and compare it to cotton, as well as discuss wool prices, including the differences between regular sheep wool and more expensive options like Kashmir goat wool.

So, how does wool keep us warm? Wool fibers have a unique structure that gives them insulating properties. The fibers are made up of a protein called keratin, which is arranged in a spiral pattern. The spirals in the fibers can trap pockets of air, which helps to retain heat and keep the body warm. In addition, wool fibers are naturally crimped, which also helps to create air pockets and increase insulation.

Absorbs Moisture And Trnspires It To The Air

Wool is also able to absorb moisture, which helps to regulate body temperature. When the air is humid, wool fibers will absorb moisture from the air and release it when the air is dry, helping to keep the body cool. Conversely, when the air is dry, wool fibers will absorb moisture from the body and release it into the air, helping to keep the body warm. This moisture-wicking property is one of the reasons why wool is such a popular choice for outdoor clothing and blankets.

Now let’s compare wool to cotton, another natural fiber that is commonly used for clothing and other textiles. Cotton fibers are also made up of keratin, but they are not arranged in a spiral pattern like wool fibers. Instead, they are straight and smooth, which means they do not have the same insulating properties as wool. Cotton is also not as good at absorbing moisture as wool, which means it does not regulate body temperature as effectively.

Does Cotton Have Any Advantages?

While cotton is not as good at keeping the body warm as wool, it does have some advantages. For one, it is more breathable than wool, which means it allows for better air circulation and can help to keep the body cool in hot weather. Cotton is also softer and more comfortable to wear than wool, which makes it a better choice for some clothing items, such as t-shirts and underwear.

Now that we’ve compared wool to cotton, let’s talk about wool prices. Wool is generally more expensive than cotton, although the price can vary depending on the type of wool and the quality of the fibers. Regular sheep wool is the most common type of wool and is usually the least expensive option. It is strong, durable, and versatile, making it suitable for a wide range of applications.

More Expensive Wool Variations

There are also other types of wool that are more expensive, such as merino wool and Kashmir goat wool. Merino wool is a type of fine, soft wool that comes from merino sheep, a breed that is known for producing high-quality wool. It is often used for clothing and is known for its comfort and breathability.

Kashmir goat wool, also known as pashmina, is a type of fine, soft wool that comes from the Cashmere goat, a breed that is native to the Kashmir region of India. It is known for its luxurious feel and is often used for high-end clothing and accessories. Kashmir goat wool is typically more expensive than regular sheep wool and other types of wool due to its rarity and the fact that it is more labor-intensive to produce.


In conclusion, wool is a natural and renewable fiber that is highly prized for its warmth, softness, and versatility. It is produced by various mammals, including sheep, goats, and rabbits, and is used in the production of a wide range of clothing and home textiles. The price of wool can vary based on a number of factors, including the type of wool, the location and method of production, and the quality of the fiber. Whether you are looking for a warm and durable fabric for your winter coat or a soft and luxurious fabric for a special occasion, wool is a great choice that is sure to meet your needs.
