Woolen items made from thick, tough fibers are more likely to itch your skin when worn. Soft wool does not have such a pronounced “piercing” ability. Ingun Grimstad Klepp, ethnologist and clothing history expert from the University of Oslo in Norway, explains this topic said Live Science.
The expert explained that thick wool fiber is generally stiff and inflexible. Such things can cause discomfort and itching when rubbed against the skin. At the same time, wool clothing made from finer, softer fibers such as merino wool or alpaca fleece can help relieve irritation.
Another important factor that determines the “spikiness” of a sweater is the presence of lanolin in the raw material (wool), a waxy substance secreted by the sebaceous glands of sheep, camels and other animals. Lanolin as a single product is suitable for many people as a skin moisturizer, but some may experience allergic reactions to it. At the same time, wool itself is not allergenic.
