Cotton
Fire point: 210 °C (410 °F)
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective capsule, around the seeds of cotton plants of the genus Gossypium. The fiber is almost pure cellulose. Under natural condition, the cotton balls will tend to increase the dispersion of the seeds.
Cotton is somewhat flammable, especially lighter ones that hold a lot of air. Some is chemically treated to reduce flammability. Many cottons are also blended with other natural fibers, such as linen, for particular properties, or to add texture and strength to the fiber.

Wool
Wool is the dense, warm coat of sheep, also called a fleece. Wool is used in a variety of textiles and can be found woven or knitted.This material is highly flame resistant, it is also highly durable, able to stretch up to 50% when wet and 30% when dry. In addition, wool has great moisture wicking properties, pulling moisture into the core of the fiber so that it doesn't feel wet or soggy to the wearer. It pulls moisture away from the skin, as well, and is worn by people in a wide variety of situations who prefer the feeling of dry air next to the skin to the clammy sense of perspiration.
