What common property of wool is beneficial for clothing?

The beneficial property of wool for clothing is flame resistance. Wool has a natural structure that makes it inherently more flame-resistant compared to many synthetic fibers and even some other natural fibers. When exposed to flame, wool tends to self-extinguish rather than burning readily, which can provide an added layer of safety in certain clothing applications, especially in workwear or situations where there may be exposure to heat or flames.

Additionally, this flame-resistant quality is due to the unique chemical composition and physical structure of wool fibers, which helps it maintain its integrity and reduce the risk of ignition. Other properties of wool, such as its ability to wick away moisture and provide insulation, also contribute to its popularity in clothing; however, flame resistance is specifically a key attribute for safety in various settings.
