Mostly good heat insulation properties.
Wool is known for its excellent thermal properties as it insulates well, keeping the body warm in cold weather. It is also breathable, allowing moisture to escape, which helps regulate body temperature. Additionally, wool can retain its insulating properties even when wet.

One of the properties of wool is that it does not burn easily.When subjected to flames, it will smoulder instead.
Alpaca wool is fine, soft, and generally comes in 8-12 inch long fibers. It has a good luster and is an extremely good insulative wool.
Physical properties of wool are the following; it is resistant to dirt and wear and tear, does not wrinkle easily, lightweight and versatile, smolders over flame instead of burning, hard wearing and absorbs moisture.
Hemp is more sustainable than wool because it requires less water and pesticides to grow. Hemp is also more durable and has better moisture-wicking properties compared to wool. Wool, on the other hand, is better at regulating temperature and has natural fire-retardant properties.
Sheep's wool is unique for its lanolin, the soft, waxy substance taken from the wool and used as a softening agent and in ointments.Sheep's wool is also fire-resistent. Unlike cotton and other fibres which burn readily, wool will only smoulder, and not catch fire easily.
Wool fabrics are made from wool -- as are some wool blend fabrics, which contain less than 100% wool.
Acrylic socks are generally softer and more comfortable than wool socks, but wool socks are more durable and have better moisture-wicking properties. Wool socks are better at keeping your feet dry and warm, while acrylic socks may feel more cozy and cushioned.
When wool is dipped in sulphuric acid, it undergoes a process called sulfonation. The acid reacts with the wool fibers, breaking down the protein structure and causing them to dissolve. This process can be used to modify the properties of wool for various industrial applications.
Wool can absorb up to 30% of its weight in water without feeling damp. Wool fibers have a natural resistance to absorbing moisture, which allows for efficient moisture management properties.
