To make wool, producers harvest the hairs of animals and spin them into yarn. They then weave this yarn into garments or other forms of textiles. Wool is known for its durability and thermally insulating properties; depending on the type of hair that producers use to make wool, this fabric may benefit from the natural insulative effects that keep the animal that produced the hair warm throughout the winter.
While finer types of wool might be used to make garments that directly contact the skin, it’s much more common to find wool used for outerwear or other types of garments that don’t make direct bodily contact. For instance, most of the world’s formal suits consist of wool fibers, and this textile is also commonly used to make sweaters, hats, gloves, and other types of accessories and apparel.
