Commonly Used Wool Care Terms and Jargon:
Felting: a process of tightly binding together wool fibers using heat. With regards to wool covers, felting refers to shrinking. Most wool is felted to some extent, but wool can always be shrunk more. Never dry your wool in the dryer!
Lanolin: a waxy substance found on sheep's wool and extracted from shorn wool.
In nature, lanolin protects the skin and wool of the animal. Lanolin can be reintroduced to wool items to help make them waterproof and protect against dirt.
Longies: long wool pants used a cloth diaper cover
Shorties: shorts made of wool that are used as a cloth diaper cover
Soaker: a wool diaper cover. Can also refer to the absorbent material in the middle of a cloth diaper.
Tepid water: lukewarm or room temperature
Wicking: to absorb or draw off liquid. In the case of wool covers, wicking can be a good thing. Wool has the amazing ability to be water resistant and to absorb up to 30% of its weight in liquid. You want your wool to wick the moisture from the diaper underneath into the wool cover. However, if you find your wool cover wicking through onto clothes, you may want to add additional absorbency to the diaper and/or lanolize your wool cover.
