Polywool is a mixture of two fibers.

Polywool is a blend of two fibers - polyester and wool. It is made by combining polyester fibers with wool fibers to create a fabric that exhibits the properties of both materials. This combination results in a textile that is durable, easy to care for, and provides the warmth and softness of wool.

Polyester is a synthetic fiber that is known for its strength, durability, and resistance to wrinkles and shrinkage. It is often used in the production of clothing, upholstery, and other textiles. Polyester fibers are made from a petroleum-based polymer that is extruded and spun into yarn.

Wool, on the other hand, is a natural fiber that is derived from the fleece of sheep or other animals. It is known for its excellent insulation properties, as well as its softness and comfort. Wool fibers are made up of protein molecules that have a unique structure, allowing them to trap air and retain heat.

When polyester and wool fibers are combined to create polywool, the resulting fabric benefits from the best qualities of both materials. The polyester fibers provide strength and durability, making the fabric resistant to wear and tear. They also contribute to the fabric's ability to retain its shape and resist wrinkles.

The wool fibers, on the other hand, contribute to the fabric's warmth and softness. Wool is a natural insulator, trapping air within its fibers to provide thermal insulation. This makes polywool a suitable choice for clothing and other textiles that require both warmth and durability.

In conclusion, polywool is a mixture of two fibers - polyester and wool. This combination results in a fabric that is both durable and warm, making it suitable for a variety of applications.
