A plus that is closely linked to its structure: the threads that compose it, in fact, intertwined with each other in a similar way to a vine, after having swelled to different levels when the humidity is absorbed and released, produce a movement of the fiber capable of to repel dirt particles that are on the surface. Result? Wool gets dirty very slowly. But there is even more: the physical and chemical structure of a wool fiber allows it to absorb or neutralize even multiple chemicals.
