There are a few differences between virgin wool and regular wool. However, the main difference is that virgin wool has not been treated, processed or woven before and is in its raw state.
The term virgin wool may also be used to identify the wool one gets from shearing a lamb for the first time. This wool is known to be very soft and fine. Both types of wool provide exceptional protection from the elements and are water resistant. Wool is naturally absorbent and is able to absorb almost 20 percent of its weight in liquid. This property also makes it very easy to dye.
