To put it simply, the characteristics of wool fabrics are good drape, increased glossiness, and less pleated, while pure wool fabrics have good air permeability, elasticity and stretchability, more texture, and more natural and soft gloss of the fabric.
1. The hygroscopicity of wool. Wool is a natural fiber with good hygroscopicity. Studies have shown that its hygroscopicity is better than conventional synthetic fibers and natural fibers such as cotton and silk under any temperature and humidity conditions.
2. The coolness of wool. When the human body sweats, because wool has high moisture absorption, it can maintain the humidity of the air around the skin in a lower range. This is one of the reasons why wool fabrics are comfortable and dry in summer.

3. High water absorption: Wool is a very good hydrophilic fiber and is very comfortable to wear.
4. Warmth retention: Because wool is naturally curled, many stagnant air areas can be formed as a barrier.
5. Durability: Wool has very good stretchability and elastic recovery, and has a special hair scale structure and excellent flexibility zd, so it also has good appearance retention.
Shortcoming:
Felting reaction: a unique and important feature of wool, which is a phenomenon caused by the scales on the surface of the wool fiber. When the hair scales on the surface of the wool encounter mechanical forces (vibration friction and pressure, etc.), heat and water, the wool sinks to its roots. As the wool sinks, the edges of the hair scales are hooked and entangled to the point where it cannot be restored to its original length. As a result, the shrinkage is severe. Under extreme conditions, wool can be collected to half of its original size (in clothing, it is normal to shrink by 80%).
